] I have a Cermark Pitts which requires 4 aileron servos. I have the bottom wing servos y'd into channel 1 and the top wing servos y'd into channel 8. I programmed the radio so that auxiliary 2 (channel 8) is slaved to channel 1 with 100% response and trim turned on. The servos function correctly; however, I discovered this morning that the electronic trim button only moves the channel 1 servos, the channel 8 servos do not follow. Is this normal? Is there something I am missing?
The way it works now, the plane is flyable, but I would like to have trim command over both channels. The programmed sub-trim control works separately for each of the two channels.
