It keeps up fairly well, though the motors being variable speed will never be perfect.

The variable speed motors are the weak point in the system.

I have however cut my prop down by about 3/8' on each side, I did it from something I read about better response.

I forget where I read about doing it, but it seems to help, I may try cutting it even more, say another 3/8" for 3/4" in total.


Just FYI the tail on a T-Rex is variable pitch and that system is incredible, like a rock.


That new Heli-Max Axe looks pretty good, I want a barebones one so I can put the DX6 and a brushless motor in it.
