I have an Aerohawk Electric heli and have been training through approx. 10 battery packs. Have used it for almost a week.
I have recently startad in small attempts to put it in the air for a couple of seconds.

When the heli lifts to the air the heli is stable but the tail rotates anti-clockwise, and I have to put it down???

I am pushing the rudder to the max to compensate this but there is not enough power?? , the tail just start moving gradually faster and when it has rotated 90 degrees I put it down when I cannot correct this?

One the ground, the tail rotor seems to need different trim at different main rotor speeds?
This is probably correct, but from far left to far right???

Happy for any suggestion, testing again tonight
