4 Channel Radio • This is your basic non-computerized 4 channel radio - Trainer Switch Aileron/Elevator Throttle/Rudder Nosewheel Trims On/Off Switch Control direction of servo movement
Definitions • Trainer switch – allows the instructor to take control of the aircraft for training • Trims – sets the neutral position of the control surfaces for straight and level flight • Throttle – controls the power developed by the engine
Definitions • Rudder – controls the yaw of the aircraft, or more simply its side to side movement
Definitions • Elevator – Controls the pitch of the aircraft
Definitions • Ailerons – Control the roll of the aircraft
Quiz time… • What would this do to the aircraft?
Answer… • This would move the elevator down, thus pitching the aircraft down.
Quiz time… • What would this do to the aircraft?
Answer… • This would increase the throttle, speeding up the aircraft.
Quiz time… • What would this do to the aircraft?
Answer… • This would move the right aileron up, the left aileron down, and start a turn to the right.
Quiz time • What would this do to the aircraft?
Answer… • Move the rudder to the left, thus moving the tail to the right and the nose to the left. It would also move the nosewheel to the left.
Practicing • Sitting with your transmitter and thinking through a flight can help quite a bit when it comes time for your next lesson. This is also known as “chair flying” • There are a number of flight simulators on the market that quite accurately recreate R/C flying
