I have a futaba 9c super that when atached to an electric motor seems to be going past the proper rpm because I can only go to half throtle before things get scary. I have blown out and edf fan unit because of it and I don't want to wreck any more parts till I get it figured out. I have tryed moving my end points put that has not helped is there something I am missing on my radio or somthing that I have not done?.

Re: Futaba 9c super throtle problems

Not usually a radio problem. More likely the batt, ESC, motor, rotor problem. What is the component makeup of what you have?? Makes etc?

Re: Futaba 9c super throtle problems

Hi there. I don't have this radio, but most high end radios will have a throttle curve. Can you adjust the throttle curve to bring it down to a lower point. You mentioned adjusted the endpoints, but try playing around with the throttle curve and see if it helps. Just a thought.

Re: Futaba 9c super throtle problems

I would put a spare servo or one in the plane on the throttle channel, and exercise it. If it behaves normally (ie mive to expected throw, no jitter or jump), then look to the esc. Do you have a ferrite choke on the esc cable to the rx? What esc, motor, battery setup are you using?
