I'm trying to program the setup in my new Sheek's Me 109. I am using a Turnigy 4250, 650 Kv with an Ice 50 and a Hubin timer. I have set it up per the Norm Whittle instructions, i.e. control line, governer high, set the cell count (6), etc. and the timer set for Phoenex RPM high. The problem is no matter what I set the RPM in the timer when the motor starts it revs up to about 6000 on the tack and then backs off to about 5500. I have changed motors and timers, and it is a new ESC. Any suggestions?
I also tried compensated throttle and set rpm with set head speeds with the same result
