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. 90 CONTROL THROWS 1. We highly recommend setting up a plane using the control throws listed. 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. Glue the belly pan. BALANCING Ailerons : 12mm up Elevator : 12mm up Rudder : 15mm right 1. It is critical that your airplane be balanced correctly. Improper balance will cause your plane to lose control and crash. 12mm down 12mm down 15mm left 12mm 12mm THE CENTER OF GRAVITY IS LOCATED 95mm BACK FROM THE LEADING EDGE OF THE WING, AT THE FUSELAGE. Aileron Control 2. Mount the wing to the fuselage. Using a couple of pieces of masking tape, place them on the top side of the wing 95mm back from the leading edge, at the fuselage sides. 12mm 12mm 3. Turn the airplane upside down. Place your fingers on the masking tape and carefully lift the plane. Elevator Control 4. If the nose of the plane falls, the plane is heavy nose. 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. 15mm 15mm Rudder Control 95mm FLIGHT PREPARATION PRE FLIGHT CHECK LATERAL BALANCE! 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. 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. 14
I/C FLIGHT GUIDELINES When ready to fly, first extend the transmitter aerial. Switch on the transmitter. 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. Check that the transmitter batteries have adequate power. Switch off the receiver. Switch on the receiver. Check that the wings are correctly fitted to the fuselage. ALWAYS take off into the wind. Switch off the transmitter. 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. Made in Vietnam
