I'm using HS-225's on my ailerons and agree with the others that stated the HS-85's are not the best choice. I'm using HS-605's for rudder and elevator (they work great!) and HS-425's on the throttle and flap.

I do use the flaps for every landing. They are fun, but probably not needed. I would not use the HS-85's on the flap either... you need to be able to move it manually (power off) and the 85's I've had are prone to bind when unpowered.
