I have a trex 700e F3C Stock motor and CC 120HV speed control. When I get about 40% throttle the motor speed starts changing (pulsing) with tail jumping. Can anyone tell me what I should check. I'm Guessing its the speed control.

What is your voltage cut off set at? What about current limiting? What size batterys and how old are they?

Are the blades on the heli or just testing on bench? Gov mode can do this and testing without blades

Cut off set at 3.2, voltage limit can't remember, Blades are on, Volts 5100 35c x2, 5-7 cycles on batteries and charged them an hour before with hyperion charger. I have about 30-40 flights on this heli with out any problems.

I had just flown it 10 minutes before with no problems hovering w/some forward flight (not much).

Is it in gov mode? If so set it to flat curves and see if it is still there, may be the gov acting up for some reason. Maybe check the logs and see if anything looks out of place.

I had similar problems some time ago, downgraded the ESC firmware and problem solved.
