Trex 500 - Castle 75
Just installed my Castle 75 and changed at the same time to a 15 tooth pinion. Goverend IU 1 & 2 to 2700 but when flicking to IU I don`t that high headspeed.

Previously with my old ESC I used a 14T pinion and goverened to 2650 and then got much higher headpseed. I have set the endpoints so this can`t be it. Any suggestions?

My setup:

Futaba T8J
Castle 75
Turnigy 1600kv
Turnigy 3000mAh 30-40C

Change Info
You probably did this, but I have to ask, did you change the gear ratio info in the ESC for your pinion change??
Also, as you put in your HS's, did you read the info box so that you would know where to set your throttle curve points//

Yes, pinion ratio change (162/15)and TC set to 0,30,30,30,30,30 and 70,70,70,70,70 all acc to Castles instructions.

Could it have to do something with the settings like poles in the motor, PWM frequenz, timing?

I have set this to 8 poles and 12PWM and medium timing.

Does anyone know if this motor has 8 or 10 poles (Turnigy H3126, 1600kv)

Had To Ask..
Yes the pole count and timing are both important..
If you can see inside your motor you can count the magnets and that is your pole count...it would be much easier if they would all list this info.. also on the timing try the outrunner setting and drop your pwm to defalt for now and give that a try...

Are you using the Governor in the Castle ESC this time? Did you go through the TX to ESC calibration sequence for throttle?

What is the current limit set at? Should be Insensitive, or Disabled.
