Hello

I have a strange issue with my esc motor.
Have uset this setup for 1year.

I have loaded the software to a 2.gen mod with turbo function
Have played with settings, no big diffrence noticed.
Now the issue, when i give full trothle from stand still, the motor makes a sound similar to a slipping diff. Also does this when car is at speed and i give full throtle.
Same issue when sensor cable is out.
Same thing is now gone wrong with my 6.5v3 motor.


I did the wiring wrong to the motors once, the b and c wire where switched. Is it possible that i fryed the sensor boards?
:cry:

Battery not able to deliver enough power?
Esc settings messed up?

Sounds like sensor board/cable.

Sounds like sensor board/cable.

But when sensor cable removed still same issue. Just tested the bearings and they where totaly shot! So ill try replacing them.

Anyone know where to get new bearings, and the dimensions of the bearings?

If the problem is still there with the cable removed, then that should tell you the cable isn't working

is there any drive or just a noise the slipper/diff slipping??
could be the rotor has debonded from the shaft,

when it happens the drive is reduced, but car accelerates very slow.
is it possible to super glue the rotor back?

Just buy a sintered rotor, it will run cooler, and not do that!

Please do not try and super glue or CA glue the rotor. It will not hold long after the motor heats up while running and can damage the rest of the motor.

It would be best to make sure your sensor board and bearings are working correctly and also use a new rotor.

nether sensor nor bearings will make a car look like its drive is reduced with a noise like diff slipping or slipper noise,if there defo tight it has to be the rotor
