BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.
13
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

I/C FLIGHT GUIDELINES
Always operate in open areas, away from factories, hospitals, schools, buildings and houses etc. NEVER fly your aircraft close to people or built up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt sleeves, scarves) or any other loose objects that could be caught or drawn in, away from the propeller. Take care at ALL times.
Keep all onlookers (especially small children and animals) well back from the area of operation. This is a flying aircraft, which will cause serious injury in case of impact with a person or animal.
NEVER fly near power lines, aerials or other dangerous areas including airports, motorways etc.
NEVER use damaged or deformed propellers or spinners.
DO NOT dispose of empty fuel containers on a fire, this can lead to an explosion.
NEVER fly in wet conditions or on windy or stormy days.
ALWAYS adjust the engine from behind the propeller, and do not allow any part of your body to be in line with the propeller.

When ready to fly, first extend the transmitter aerial.
Operate the control sticks on the transmitter and check that the control surfaces move freely and in the
CORRECT directions.
ALWAYS land the model INTO the wind, this ensures that the model lands at the slowest possible speed.
Switch on the transmitter.
Check that the transmitter batteries have adequate power.
Switch off the receiver.
Switch on the receiver.
ALWAYS take off into the wind.
Switch off the transmitter.
Check that the wings are correctly fitted to the fuselage.
If the model does not respond correctly to the controls, land it as soon as possible and correct the fault.
Empty the fuel tank after flying, fuel left in the tank can cause corrosion and lead to engine problems.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.
13
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.
13
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.
13
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

· (1) 165mm x 250mm foam.
INSTALLING THE STOPPER ASSEMBLY
1. The stopper has been pre-assembled at the factory.
2. Using a modeling knife, cut one length of silicon fuel line (the length of silicon fuel line is calculated by how the weighted clunk should rest about 8mm away from the rear of the tank and move freely inside the tank). Connect one end of the line to the weighted clunk and the other end to the nylon pick up tube in the stopper.
3. Carefully bend the second nylon tube up at a
45 degree angle (using a cigarette lighter). This tube will be the vent tube to the muffler.
4. Carefully bend the third nylon tube down at a
45 degree angle (using a cigarette lighter). This tube will be vent tube to the fueling valve
!
When the stopper assembly is installed in the tank, the top of the vent tube should rest just below the top surface of the tank. It should not touch the top of the tank.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

I/C FLIGHT GUIDELINES
Always operate in open areas, away from factories, hospitals, schools, buildings and houses etc. NEVER fly your aircraft close to people or built up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt sleeves, scarves) or any other loose objects that could be caught or drawn in, away from the propeller. Take care at ALL times.
Keep all onlookers (especially small children and animals) well back from the area of operation. This is a flying aircraft, which will cause serious injury in case of impact with a person or animal.
NEVER fly near power lines, aerials or other dangerous areas including airports, motorways etc.
NEVER use damaged or deformed propellers or spinners.
DO NOT dispose of empty fuel containers on a fire, this can lead to an explosion.
NEVER fly in wet conditions or on windy or stormy days.
ALWAYS adjust the engine from behind the propeller, and do not allow any part of your body to be in line with the propeller.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.
13
FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

BALANCING
1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash.
THE CENTER OF GRAVITY IS LOCATED
150mm BACK FROM THE LEADING EDGE
OF THE WING, AT THE FUSELAGE. This location is recommended for initial test flying and trimming. There is a 10mm margin forward and aft. BALANCE A PLANE UPSIDE DOWN
WITH THE FUEL TANK EMPTY.
2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 150mm back from the leading edge, at the fuselage sides.
3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane .
4. If the nose of the plane falls, the plane is nose heavy. To correct this first move the battery pack further back in the fuselage. If this is not possible or does not correct it, stick small amounts of lead weight on the fuselage under the horizontal stabilizer. If the tail of the plane falls, the plane is tail heavy. To correct this, move the battery and receiver forward or if this is not possible, stick weight into the firewall. When balanced correctly, the airplane should sit level or slightly nose down when you lift it up with your fingers.
150mm
2. The control throws should be measured at the widest point of each control surface.
3. Check to be sure the control surfaces move in the correct directions.

LATERAL BALANCE
!
After you have balanced a plane on the C.G. You should laterally balance it. Doing this will help the airplane track straighter.
1. Turn the airplane upside down. Attach one loop of heavy string to the engine crankshaft and one to the tail wheel wire. With the wings level, carefully lift the airplane by the string. This may require two people to make it easier.
2. If one side of the wing fall, that side is heavier than the opposite. Add small amounts of lead weight to the bottom side of the lighter wing half's wing tip.
Follow this procedure until the wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using the control throws listed.

FLIGHT PREPARATION
PRE FLIGHT CHECK
1. Completely charge your transmitter and receiver batteries before your first day of flying.
2. Check every bolt and every glue joint in your plane to ensure that everything is tight and well bonded.
3. Double check the balance of the airplane
4. Check the control surface
5. Check the receiver antenna . It should be fully extended and not coiled up inside the fuselage.
6. Properly balance the propeller.
7. Use at least 5 rubber bands per side to hold the wing onto the fuselage.
We wish you many enjoyable flights with your plane and once again thank you for your choosing a Phoenix Model's product.

I/C FLIGHT GUIDELINES
Always operate in open areas, away from factories, hospitals, schools, buildings and houses etc. NEVER fly your aircraft close to people or built up areas.
THE PROPELLER IS DANGEROUS
Keep fingers, clothing (ties, shirt sleeves, scarves) or any other loose objects that could be caught or drawn in, away from the propeller. Take care at ALL times.
Keep all onlookers (especially small children and animals) well back from the area of operation. This is a flying aircraft, which will cause serious injury in case of impact with a person or animal.
NEVER fly near power lines, aerials or other dangerous areas including airports, motorways etc.
NEVER use damaged or deformed propellers or spinners.
DO NOT dispose of empty fuel containers on a fire, this can lead to an explosion.
NEVER fly in wet conditions or on windy or stormy days.
ALWAYS adjust the engine from behind the propeller, and do not allow any part of your body to be in line with the propeller.
14
When ready to fly, first extend the transmitter aerial.
Operate the control sticks on the transmitter and check that the control surfaces move freely and in the
CORRECT directions.
ALWAYS land the model INTO the wind, this ensures that the model lands at the slowest possible speed.
Switch on the transmitter.
Check that the transmitter batteries have adequate power.
Switch off the receiver.
Switch on the receiver.
ALWAYS take off into the wind.
Switch off the transmitter.
Check that the wings are correctly fitted to the fuselage.
