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 A B Coat one half of the dihedral brace with epoxy up to the center line.

These value will be suitable for average flight requirements. Adjust the values to suit your particular needs. 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.
