alteration would have accomplished same thing rate gyro will stabilize model flight causing actual control surface movement se lected servo example aircraft deviates its course result turbu lence

flight since rate gyros can directly affect quality flight pilot input transmitter possible fact probable higher scores some maven ners could awarded usa result something other piloting skill rate

ability make corrections rapidly precisely contributes toward first place trophies during competition Mr Myers comments directed mainly RC-B4-t applies rate gyros also makes unjustifiable comments regard ing use push buttons todays trans mitters stases Push button maneuver happens - thats definition addition erroneously referring tu push button automatic pilot Mr Myers blames RC-94-t
