2. 4 Channel Radio  This is your basic non-computerized 4 channel radio - Trainer Switch Throttle/Rudder Nosewheel Trims Control direction of servo movement On/Off Switch Aileron/Elevator

3. 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

4. Definitions  Rudder – controls the yaw of the aircraft, or more simply its side to side movement

5. Definitions  Elevator – Controls the pitch of the aircraft

6. Definitions  Ailerons – Control the roll of the aircraft

7. Quiz time…  What would this do to the aircraft?

8. Answer…  This would move the elevator down, thus pitching the aircraft down.

9. Quiz time…  What would this do to the aircraft?

10. Answer…  This would increase the throttle, speeding up the aircraft.

11. Quiz time…  What would this do to the aircraft?

12. Answer…  This would move the right aileron up, the left aileron down, and start a turn to the right.

13. Quiz time  What would this do to the aircraft?

14. 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.

15. 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
