I have put the 2nd aileron on a separate channel so that I can have differential (defiantly makes my plane fly better). It was working fine with the APM not connected. I have set it up with the wiki brief.
What happens with mine is, all though both ailerons work correctly in all modes, differential will limit the roll in one direction, eg full left roll (both ailerons), half right roll (both ailerons). I cant see any other way to set it up.
Just discovered another disadvantage of having 2 aileron channels. If the APM resets (dont know why it should) then most of the controls are available in manual after about 3sec but the 2nd aileron remains in its deflected state for about 12sec.
I may just use a ‘Y’ lead UFN.

I tried dual ailerons last summer but every time I activated the "CROW" switch to reduce lift for landing it would go into a hard roll. I could never figure it out.
I have not tried the latest firmware with dual ailerons. It was very dangerous so I don’t want to try that again it it’s going to go hard over when I am trying to land. Apparently the developers don’t bother to test this configuration. Has anyone been able to figure out the CROW landing mode – maybe some code modification?

I tried setting up a second aileron a few days ago because I wanted to use spoilerons but while I could get the dual aileron setup to work reasonably well the spoileron would never work correctly. The impression I got was that what had been setup in the software was just a mirror of channel 1, not a true dual aileron with dual inputs from the Rx allowing differential and flaperons/spoilerons. I stand to be corrected but I suspect this just hasn't been developed/honed properly in the software.
