I am about to setup my first fuel plane after flying electric for a couple of years. With electric, the throttle is controled thru the ESC, and channel 3 on the receiver. With fuel, channel 3 controls the throttle servo. Does this eliminate my using a 4 channel receiver? I am using the normal air, elev, throttle, and rudder contrrols. Is a duplex connector used to combine one of the channels with the battery input?
Or is the normal fuel setup to use a least a 5 channel receiver?
