vq VQA048 Instruction manual
The vq VQA049 is a radio-controlled almost ready-to-fly engine powered all balsa plane, suitable for experienced modelers. With a wingspan of approximately 61.8 inches and a fuselage length of 48.8 inches, it is a substantial model that requires a minimum 6 channel radio for airplane with 6 servos (EP version) and 7 servos (GP version). It can be powered by a .60 - 2 cycle engine with 6 servos (EP version) and 7 servos (GP version), a .90 - 4 cycle engine with 6 servos, or an electric equivalent with a Quantum 4120/07 Brushless Motor.

2- Joining the wing
Before gluing:
- Draw the center line on the wing joiner.
- Trial fit each part before gluing . Be certain that there are no gaps.
If the parts will join, but with a gaps, sand or trim the parts a little at
a time until the parts meet exactly with no gaps.
- Check for the correct dihedral angle
Draw the center line on the wing joiner
Coat one half of the dihedral brace with epoxy up to the center line. Install the epoxy-coated side of the dihedral brace into the wing joiner cavity up to the center line.

There should be a minimal hinge gap and the end of the elevator should not rub against the horizontal stabilizer.
When satisfied with the and alignment, hinge the elevator to the horizontal stabilizer using 5 minute epoxy. Make sure to apply a thin layer of epoxy to the top and bottom of both hinges and to inside the hinge slots. Repeat the previous procedures to hinge the second elevator to the other side of the horizontal stabilizer.

IMPORTANT: Please do not clean your model with pure alcohol, only use liquid soap with water or use glass cleaner to clean on surface of your model to keep the colour not fade.
PRE-FLIGHT CHECKING AND ADJUSTING YOUR MODEL
It is almost impossible to fly your model without checking and adjusting your model. You can stop easily if your car is not running strait. But you cannot stop your airplane after take off. Your plane could go right or left. Or even go up or down. Without understanding these instruction before flying the Ki-61, you might otherwise have difficulty in flying, or crash the plane. If you are new to Radio Control flying, you should not fly the Ki-61 but have an expert fly it. Even if you are experienced pilot, read this before your first flight.
PRE-FLIGHT CHECK
1-Balance: There is very important relationship between the CG position and stall characteristic of an airplane
or knife-edge performance. An aft CG will make the plane snap roll instead of making a clean stall. And your
plane goes to down side at knife edge flying instead of strait. To measure the CG position, measure 4 ~ 4-1/8”
(100 ~ 105mm) from leading edge ( a + / - 13/64” = 5mm is fine).
2-Check the operation and direction of the elevator, rudder, ailerons and throttle:
ELEVATOR RUDDER AILERON
CAUTIONS FOR SAFETY
Ensure the airfield is spacious enough.
Ensure the spinner and propeller are securely attached. Immediately disure defective propeller as well as deformed spinners.
Adjust the engine always from behind, but never from infront or the sides as rotating propeller may badly injure you.
Do not allow watching people to get too close to a rotating propeller.
Fully extend the transmitter and receiver antenna.
Always take off and landing your airplane into the wind.
Switch off the transmitter and receiver after landing.
Do not fly your airplane above people standing around.
BEFORE FLYING CHECK EVERYTHING
Before each flight, inspect the airplane for any loose parts. Check the hinges, make sure the pushrods are still firmly attached, and check the engine mounting bolts. In general, check everything on the plane that might possibly come loose.
CHECK THE FREQUENCE BEFORE FLYING
DO NOT FLY NEAR A POWER LINE
The power lines cause radio interference, so avoid flying near them.
WARNING
Do not put in a large-than recommended engine. A bigger engine does not necessarily mean better performance.
