Hi everyone, I’m having some problems setting up the ESC for my e-foil.
I have a FSESC 200A 60V for a 65161 / 120KV motor (all flipsky) with a Maytech remote controler.
12S 10P Li-ion battery.
With firmware ‘VESC_default_no_hw_limits’ I configured the motor as FOC, everything works fine but the motor does not exceed 2500 RPM, I think it should go faster.
I hope I was able to explain the problem, thanks in advance for your help, and sorry for my English.

</motor_quality_description>Try this thread. I haven’t updated it like I promised but it’s still good.
thanks I do some tests, I’ll let you know
Look at your erpm , here you enter 6 poles , calculation are made usually on pair pole , so you may have 5000rpm actually
