Note on Lithium Polymer Batteries
Lithium Polymer batteries are significantly more volatile than alkaline or Ni-Cd/
Ni-MH batteries used in RC applications.
All manufacturer’s instructions and warnings must be followed closely. Mishandling of
Li-Po batteries can result in fire. Always follow the manufacturer’s instructions when disposing of Lithium Polymer batteries.
During the course of building your model we suggest that you use a soft base for the building surface.
Such things as a foam stand, large piece of bedding foam or a thick bath towel will work well and help protect the model from damage during assembly.
The most important part of building your model is guaranteeing that it is straight when completed. A flat work surface and square will be the most important items during this build.

If you lay the fuselage on the edge of a flat surface so that the landing gear doubler is hanging off of the edge and just the top half above that is on the table it will allow you to keep the fuselage very straight during the first steps.
1. Locate the left horizontal fuselage and main fuselage. The left horizontal fuselage will be printed on top and white on the bottom. Test fit the horizontal fuselage to the main fuselage. Check that the horizontal fuselage lines up at the front with the main fuselage.
2. When gluing the horizontal fuselage to the main fuselage, do not apply glue toward the tail after the last tab. This is necessary to properly install the horizontal stabilizer.
3. Remove the horizontal fuselage from the main fuselage. Apply a bead of foam-safe CA to the left horizontal fuselage where it contact the main fuselage. Do not apply CA to the rear section of the horizontal fuselage as noted in the previous step.

4. Position the horizontal fuselage on the main fuselage, again making sure that they line up at the front. Use a square at multiple points on the fuselage from nose to tail to guarantee the horizontal fuselage is square to the main fuselage.
Check square from both the top and bottom side of the fuselage. Allow the CA to fully cure before proceeding.
5. Position the left upper diagonal brace as shown.
Use the alignment point in the photo to properly position the brace.
The brace will just cover the
holes when aligned properly. Also make sure it is aligned at the front of the fuselage. The angle of the brace will be 45° to the fuselage sides and will be equal distance on both the horizontal and vertical fuselage. Use foam-safe CA to glue the diagonal brace to the main and horizontal fuselage. Do not apply CA to the rear section of the diagonal brace, similar to that of the horizontal fuselage.
Make sure that while you are gluing the diagonal brace to the fuselage you do not put a lot of pressure on the assembly. You could create a warp in the fuselage assembly.
6. Use foam-safe CA to glue the left lower diagonal brace as shown.
You can temporarily use the foam firewall to locate and mark the angle of the diagonal brace at the front of the fuselage.
Make sure to use a square on the bottom side of the horizontal fuselage when gluing the diagonal brace to the vertical and horizontal fuselage.

7. Locate the horizontal stabilizer. Note the coloring scheme on the top of the stabilizer. Carefully fold the elevator on the stabilizer as shown so it can be installed into the fuselage.
8. Slide the folded horizontal stabilizer into the fuselage. Unfold the elevator and position the stabilizer, but do not apply any glue to the stabilizer at this time.
9. Repeat Steps 1 though 5 to install the right upper diagonal fuselage brace with foam-safe CA.
Again, make sure to work slowly and use a square to keep the alignment of your fuselage in check.
You will not glue the lower right diagonal brace until later in the build.
10. Locate the Depron firewall. Note the alignment points on the firewall and how they relate to fuselage. The alignment points are located on the top and left (as viewed from the front of the fuselage) as up and right thrust are built into your model. Use foam-safe CA to install the Depron firewall in the fuselage.

1. Locate the bottom wing.
2. Test fit the fuselage into the bottom wing as shown. Make sure the tabs from the fuselage are flat when inserted into the bottom wing. If not, you may induce an airfoil resulting in unwanted flight characteristics.
3. After confirming the fit between the fuselage and bottom wing, use foam-safe CA to glue the bottom wing to the fuselage. Use a square between the fuselage and bottom wing to keep them in alignment while the CA fully cures.
4. Locate the two outer struts. There is not a left or right strut, but you will want to match the trim scheme from right to left for aesthetics.
If the tail of your airplane is hanging off of the table when you are mounting the bottom and top wing it will allow the assembly to lay perfectly flat against the joint.
E-flite 4-Site Assembly Manual 7
5. Test fit the outer strut into the bottom wing as shown. Make sure the tab is flat when inserted into the bottom wing. If not, you may induce an airfoil resulting in unwanted flight characteristics.
8. Locate the top wing. The bottom side of the top wing is white with no trim scheme.
10. Remove the top wing and place it upside down on your flat work surface. Use foam-safe CA to glue the top wing to the fuselage and outer struts.
Make sure to use a square at both the struts and fuselage to keep things in alignment while the CA cures.
6. After confirming the fit between the outer strut and bottom wing, use foam-safe CA to glue the outer strut to the wing. Use a square between the outer strut and bottom wing to keep them in alignment while the CA fully cures.
9. Test fit the top wing to the fuselage and outer struts. The tab on the struts and fuselage will be flat in the top wing. If not, it may induce an unwanted airfoil that could result in unwanted flight characteristics.

x 1/32-inch (325mm x 1mm) carbon rod (two pieces on either side of the fuselage) that keep the top and bottom wings in alignment with the fuselage. Do not apply CA until instructed. The rod that runs from the top of the center cabane to the lower outer strut should be on the front of the cross.
When positioning the fuselage upside down on your work surface, the fin will need to hang off the edge of your work surface to keep the top wing perfectly flat.
2. With the top wing flat on your work surface, check that the struts and fuselage are square to the top and bottom wings. Apply a small amount of foam-safe CA at the points where the carbon rod are inserted in the top wing. The rod should be inserted completely through the wing but should not protrude past the top of the wing.
3. Make sure to keep the airframe very square while proceeding. Apply a few drops of foam-safe
CA to the carbon rods where they enter the bottom wing. Also apply CA to the junction between the carbon rods where they cross each other. You can trim off any excess rod from the bottom of the wing after all four rods have been glued at each joint.

2. Use medium grit sandpaper to lightly sand the back side of the firewall. The glue will be applied to this side of the firewall to attach it to the fuselage.
1. Locate the carbon firewall. There are four holes in the firewall: two large and two small.
The two smaller holes are the alignment points for positioning the firewall on the fuselage. These holes will be located just like the ones on the Depron firewall.
3. Match the two alignment points to those in the
Depron firewall (top and left as viewed from the front of the fuselage). Use foam-safe CA to secure the firewall to the fuselage.
4. It may be necessary to remove a small amount of material from behind the firewall to clear the motor shaft of your particular motor. You can use either a round file or hobby knife to accomplish this task.
5. Attach the motor mount to the motor following the instructions provided with the motor using a flat blade screwdriver. Note the position of the motor wires in relation to the motor, as they need to be positioned as such to connect to the speed control.

Important Information About Your Propeller
It is very important to check to be sure the propeller is balanced before installing onto the shaft. An unbalanced propeller may strip the gears or cause poor flight characteristics.
If it is necessary to enlarge the hole in the propeller or the spinner, make sure to check the balance of each afterwards.
1. Locate the propeller adapter (included with motor) that fits your particular model. Insert the adapter in the propeller, making sure it is installed in the backside of the propeller.
3. Foam-safe CA is used to glue the wheel pants to the wheel skids. A small notch in the wheel pant will align with the center ridge on the wheel skid.
Make sure there is clearance between your work surface and the wheel pants so they do not rub during take-off or landing.
5. The battery attaches roughly 25mm in front of the elevator servo. The exact position can be adjusted to correct the Center of Gravity if it is not correct according to this manual.

2. Use foam-safe CA to glue the air brake to the outer strut. Use a square to align the air brake with the outer strut as shown.
1. Locate the large and small air brakes. The air brakes are an optional part. There are two different size air brakes supplied with the 4-Site. If you are interested in flying more aggressive 3D style maneuvers you may want to leave these off. If you fly mainly in a large indoor facility, then you will want to use the smaller air brakes. If you fly in a smaller area like a one court size gym, then the larger air brakes will slow the 4-Site down more.
You may choose to try all three variations. Do this by just lightly tack gluing the air brakes on at first. Choose the set of air brakes that suits your particular flying location and flying style.
3. Use two 3

-inch (80mm) carbon rods to support the air brake and keep it from changing angle. The carbon rods are glued using foam-safe
CA. Use a square to check that the air brake is still square to the outer strut before the CA fully cures.
4. Repeat Steps 2 and 3 to install the remaining matching air brake.
E-flite 4-Site Assembly Manual
Control Throws
1. Turn on the transmitter and receiver of your model. Check the movement of the rudder using the transmitter. When the stick is moved right, the rudder should also move right. Reverse the direction of the servo at the transmitter if necessary.
2. Check the movement of the elevator with the radio system. Moving the elevator stick toward the bottom of the transmitter will make the airplane elevator move up.
3. Check the movement of the ailerons with the radio system. Moving the aileron stick right will make the right aileron move up and the left aileron move down.
4. Use a ruler to adjust the throw of the elevator, ailerons and rudder.

You will notice that when you get to the full travel of high rates on the aileron servo you will see a slight difference in the travel amount from top to bottom due to the servo linkage offset. This does not affect the flight performance of the 4-Site.
Center of Gravity
An important part of preparing the aircraft for flight is properly balancing the model.
Caution: Do not inadvertently skip this step!
The recommended Center of Gravity (CG) location for your model is 2

inches (75–90mm) back from the leading edge of the top wing at the center. Make sure to measure from the farthest point forward for accuracy. Mark the location for the Center of Gravity on the bottom of the top wing next to the fuselage as shown.
Adjust components as necessary so the model hangs level or slightly nose down. This is the correct balance point for your model. You might find that you need to shift the battery slightly to either the front or back of the fuselage to achieve the correct balance.
E-flite 4-Site Assembly Manual
Measurements are taken at the inner or widest point on the control surface.
These are general guidelines measured from our own flight tests. You can experiment with higher rates to match your preferred style of flying.
After the first flights, the CG position can be adjusted for your personal preference.
You can use a small ball driver or pen to hold the 4-Site up during balancing.
Travel Adjust, Sub Trim and Dual Rates are not listed and should be adjusted according to each individual model and preference.

Preflight Range Test Your Radio
Check Your Radio
Before going to the field, be sure that your batteries are fully charged per the instructions included with your radio. Charge both the transmitter and receiver pack for your airplane. Use the recommended charger supplied with your particular radio system, following the instructions provided with the radio. In most cases, the radio should be charged the night before going out flying.
Before each flying session, be sure to range check your radio. See your radio manual for the recommended range and instructions for your radio system. Each radio manufacturer specifies different procedures for their radio systems. Next, start the motor. With the model securely anchored, check the range again.
The range test should not be significantly affected. If it is, don’t attempt to fly! Have your radio equipment checked out by the manufacturer.
Note: Keep loose items that can get entangled in the propeller away from the prop. These include loose clothing, or other objects such as pencils and screwdrivers. Especially keep your hands away from the propeller.
1. Before each flying session, be sure to range check your radio. This is accomplished by turning on your transmitter with the antenna collapsed.
Turn on the receiver in your airplane. With your airplane on the ground and the engine running, you should be able to walk 30 paces
(approximately 100 feet) away from your airplane and still have complete control of all functions.
If not, don’t attempt to fly! Have your radio equipment checked out by the manufacturer.
2. Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction.
3. Be sure that your transmitter batteries are fully charged, per the instructions included with your radio.
Double-check that all controls (aileron, elevator, rudder and throttle) move in the correct direction.
Check the radio installation and make sure all the control surfaces are moving correctly (i.e. the correct direction and with the recommended throws). Test run the motor and make sure it transitions smoothly from off to full throttle and back. Also ensure the engine is installed according to the manufacturer’s instructions, and it will operate consistently.
Check all the control horns, servo horns, and clevises to make sure they are secure and in good condition.
Repair or replace any items that would be considered questionable. Failure of any of these components in flight would mean the loss of your aircraft.
Flying Your 4-Site
Flying the 4-Site is about as fun as it can get. Very light wing loading and extreme control throws make for some precise F3P flying. Verify that your CG is at the correct location as per the manual and that you have your rates set up to your liking.
Verify all control throws are in the correct direction and the motor spins in the correct direction as well. Point the model into the wind and add some throttle trim until the motor begins to turn. This will be your flight idle. We recommend hand launching the model if you are flying from of a rough surface.
Apply power slowly. You will find the model will become airborne very quickly and at a low speed. This model excels at flying slow and easy. Trim the model for level flight at half throttle. Only use full throttle for maneuvering.
You will find you can adjust the CG to your liking by moving the battery pack fore or aft on the fuselage.
To land the 4-Site just reduce the throttle to idle and feed in up elevator until the model settles into a slightly nosehigh attitude.
Gently fly the model down to the landing spot with a final flair at touchdown.
We hope you enjoy the 4-Site as much as we do.
Happy landings.
