at its price I'm guessing 35A
the motor cans that come with them also look like the 35A EZ-runs just re-colored

Possible causes: Improper gearing, improper soldering, faulty battery, factory defect.

He means if your motor is geared to high it will let out all of its magical smoke.

well overgearing usually burns out the motor before the esc undergearing kills the esc tho

I have run Mamba Max 6900 & 5700 setups off road without any issues. Most likely it was a defective ESC but when you buy cheap RC's you get what you pay for.
