Thanks for your answers!

I have a probleme with my setup, the motor over heat and the controller cut after 5 min of run.

My motor Feigao 540c 9L it's a 3345kv and in 14,4V the rpm goes up 50000tr/min

Does the controller have a adjustment to limit the rpm?? what i have to do for decrease the temperature??

I use a 13t pinions and a 46 T spur.

Thanks and sorry for my bad language:005:
