Electric Flight

摘要

John Krouse has coined the term TCFF (Throttle Controlled Free Flight) to describe his use of a radio to control the electric motor on a freeflight with fixed control surfaces. When flying in a gym it's nice to be able to cut the motor before the model hits the rafters and possibly hangs up. It is also quite useful to adjust the throttle to limit excessive power and unstable flight. We have found that if the model is trimmed for a turn with side thrust adjustment, the size of the circle becomes a function of throttle setting. In the extreme case it can be made to turn one way under power, the opposite direction in glide, thus achieving a pseudo directional control.
