RE: another newbie question
If you have a computer radio, there is an alternative to the y-cable. Computer radios have the ability to slave one channel to another. Using this technology you could plug one servo into the aileron channel and another into channel 6 (or another available channel). You would then go into the transmitter setup and define channel 6 to be slaved to the aileron channel. Once this is done, the transmitter sends the appropriate signal to both the aileron channel and channel 6 when you move the aileron control.
