MajorB,
Probably sounds couter-intuitive, but . . . Stock Aero.
It was designed to run on that and you'll get more out of having the craft properly trimmed, balanced and serviced than you ever would out of any advanced heli settigns. Setting a dual rate on pitch/roll (right stick on Mode 2) to about 70-90% isn't a bad idea, though.
The only minor exception would be the heli mode can give you throttle curve settings, but in all fairness, it's almost better to learn to hold an altitude in hover the hard way on a linear throttle. That way, when you move up to something bigger and fancier, you're fingers instinctively counter momentum by overshooting, then back off to the sweet-spot, or in Fast Forward Flight (FFF), you balance throttle and pitch to maintain altitude and airspeed.
BTW, Welcome to the forum!
