I am a newcomer to RC powered fixed wing but have a military fixed wing and rotary flying background. I would appreciate feedback on how a model reacts to flight both in to wind and downwind. To put it into context in a full size machine if I execute a 360 deg turn at a constant angle of bank - say 20 degs - I do not have to change the attitude or power of the aircraft to compensate for wind and my indicated airspeed does not vary. I know that to an observer on the ground my flight path is biased downwind and that my groundspeed changes relative to the wind. Flying a model I make far more power and pitch attitude adjustments to maintain level flight than I can explain. I would appreciate some insight in to this phenonima. Happy to receive answers based on the experience of fliers in addition to those which contain fundamental Principles of Flight.
