Firstly I appologise if this is seen as a silly question but I will ask it anyways.


I have run my x400 a few time now and I believe I am suffering from a motor which is running too hot.

My gear:

CC 35 ESC (none govenor mode)
AON 3500 (11 tooth pinion)
Futaba GY401
Woodies

My motor is running at 250F which I reckon is way to hot, it was hotter at 290F with a 13 tooth pinion on, which is has been changed to an 11 tooth one.

I have reduce the trottle curve down to the point where I have just enough head speed to control the tail and give me good lift (i.e at half stick 65%, 3/4 stick 75% and full stick 80%)

the pitch curve as also been reduced slightly to give me 8Deg at full stick and 5Deg at half stick.

All the gearing and shafts are free running with no binding.

Firstly is this too hot for my motor.
Secondly what else can I try to reduce the temp further.

I need to solve the problem before it damages my motor.

Thanks all

you MIGHT have already damaged it, but anyway...


try higher headspeed & less pitch.

also note that 10T pinion is recommended by x400tuning.com...i think your pinion is too big (i think this is your #1 problem)

with an 11T pinion youre doing a theoretical 3000+headspeed (efficiency not factored in)
