So Ihave a split elevator on a super sportster and made it so there's one servo for each half. The gear channel is slaved to the elevator channel. Works perfect, but for some reason when I use the elevator trim, it only works for the one half driven by the elevator channel. Is there any wa to get it to work for both? I've read through the manual and messed with the setting on the radio and can't find anything. I can trim it out using the settings, digitally in the radio to match, but I can't really do that while in flight of course.

I'm about to hook up the aelerons in the same way... aux2 slaved to aelerons, and the same will probably happen there as well.

Any help?

Thanks!
