I wouldn't use the HS85's for aileron servos. The servos only have one mounting screw per side and tends to want to move back and forth because of this. They may have the torque but the gears are tiny and I won't trust them on a control surface. The servo arms are tiny and short. This makes it harder to setup controls because you have less throw to work with. I bought some a while back based on the specs. Because of these differences in them, I only trust them to for the throttle. Bigben is right about the flaps, forget them. It just adds more servos that drain your battery and adds more weight. I have a 60 sized warbird and it lands as slow as my original LT40 without flaps, only better because wind doesn't bother it.
