I have had a T-rex 600 for a while now but it seems to not feel as stable / powerful in the air anymore. I have resorted to pitch and throttle curve setpoint from the manual and still it seems a little week. I have toyed with the possibility that my flight power 6s2p 4900 is failing but would like to get some pit/curve data from some aged heli pilots.
I do not fly 3d however I have the selector switch armed and capable...just a heli that does not feel crisp enough.
