Hello everybody
I have tekin redline 21.5 motor with mamba max pro esc on my axial scx-10

once car stopped

shaft does not rotate, but twitches - more with sensor cable and less without it
I dissasembled motor and all looks ok inside

tried another sensorless motor and it works ok

what's wrong?

ps sorry for my english

Dial your throttle trim back a little bit. Sounds like your hitting the edge of the neutral width.

I got this problem during normal driving
now tried to move throttle trims, nothing changed

If you tried another motor and it was ok my guess is the sensor board on the gen1 is goosed.

replaced the Sensor PCB
no change
any ideas?

Sounds like either a sensor harness or esc setting.

Changed a harness, updated firmware on ESC and reseted settings to default ones.

Problem is still here

So I think the problem is in motor itself

How can I disassemble motor to check coils or with ohmmeter or somehow else?
