I really like Truglodite's summary of pitch & throttle curves.

My main question is about headspeed. Since my Blade CP Pro has more slop in the head than a trex, it seems to fly more predictably in hover with fairly low headspeed. The person at my local hobby shop said the stock motor may hover at something like 1100 rpm? Whereas a trex is more like 2000? How do we know how to set headspeed at hover at a good speed for Blade CP pro? Do you need some fancy optical tach? Do you suggest an rpm?

Second, I'm not into upside down heli flying yet, so not too experienced. But I'm finding it works pretty well if my headspeed actually increases when I need more upward thrust from hover (like in windy conditions). I'm using a razor brushless, so have a bit more main motor power than I think I need. Does that make any sense?

Do you think slower headspeed in hover is more predictable & controllable? And higher headspeed is more necessary to increase roll & pitch rates as we want to get more aerobatic?

Any guidance on suggested headspeed for hovering & FFF?
Any guidance on headspeed for aerobatics? (maybe higher?)
