E-revo. Vxl instant thermal. Help?

[_paralyzed_]

if the motor gets too hot, the rotor will demagnetize. Then the motor has literally no power and it just stutters like you described.

Does it roll freely when pushed? If not there is binding somewhere, which can cause the same thing.

Does the nimh seem good otherwise? Maybe there is enough voltage drop to cause your symptoms.

Ah, gotcha, No binding, rolls fine. Ni-mh is good, just to make sure i plugged my 2s lipo in and it did the exact same thing.
