I used to have ailevators on my TT 120 powered CG Extra. IMHO, about the only thing the ailevators were good for was being able to speed up, stop, or even reverse a torque roll. Other than that, I kept the aileron mix turned off.

I'm building my UCD now. I'll probably try the ailevators on the UCD simply because the Extra program is still in my 8UAF, but the Extra has long gone to balsa heaven.
