No mods on the ailerons, but i wished I had went full width of the wing. Mine will hover at half throttle, but torque rolls right away.

Positive on the 7C. It is one the biggest gripes about this radio. I think they added that feature to the FASST 7C, though.

My rear mounted servos are mounted on hard wood blocks. I had to do this to get the clearance inside the fuse for the servos.
