The center of gravity is located 2-3/8” back from the leading edge of the wing, at the fuselage sides. This location is recommended for initial test flying and...
25 q c) check the rudder. Looking from behind the airplane, move the rudder stick to the right. The rudder should move to the right. If it does not, flip the servo reversing switch on your transmitter to change the direction. Q d) check the throttle. Moving the throttle stick forward should turn on ...
26 if you decide you have no choice but to learn to fly on your own, choosing the right place to fly your whis- per is of the utmost importance. Select your potential flying field with the following considerations: 1) look for a site that has a soft landing area. The best sites are large grassy fiel...
27 fly the airplane level for about 30 feet and allow the speed to pick up. Use the rudder to keep the whis- per tracking straight. After the whisper has picked up some speed, begin a shallow climb-out by apply- ing a small amount of up elevator. Be gentle. You don't want to overcontrol the airplane...
28 3) overcontrolling. Most new pilots try to fly like they are playing a video game. Most likely, you will never need full stick movement for any correction. Typically, you will need very little down elevator as well. Remember to move the stick in only small amounts at a time. The radio control sys...
29 watch the tail of the airplane bounce up to see if you are hitting lift. When you fly into a thermal it kicks the tail up and thus points the nose down. Despite this “dive” position your plane may actu- ally be going up in the lift. It depends on the strength of the thermal. That “up tail” is a s...
