One of the racers at my local track stopped racing after last year so i bought his set up. it was a 1/8 scale buggy (the car). It had an older modified mamba max pro with a older what i was told was an older neu 1717 it has a teal can and is larger in diameter than my 1717 mamba.

Here is the issue if i go to full throttle i would lose power to servo and lose control of the motor it would run away for a quit second then come come right back. i thought it was the esc so i put a mmm esc on it and its doing the same thing. Can a motor cause this? if so can it be fixed?
