ive got a similar problem. It reads zero rpm when it should, but ive been testing the electric motor and it will spoolup to 9000 rpm then when spooling down the rpm will jump around and even jump to 40000 just for half a second.

Ive tried deguassing it with a weak fridge magnet, but with the cowling on so im not sure how much effect it will have.

I dont have any servos attached so thats not it.

The transmitter is far enough away.

Ill try recharging the reciever battery and try again.

Any other suggestions???


PS it says in the instructions to do a manual start before attempting a full auto start. Can someone tell me what the harm in that would be given i can just shut it down with the throttle trim?
