Speed passion gt2.0 pro and 7.5v3 motor

[alex007]

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?


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