If you are geared to the moon you will burn up brushes and the springs will weaken to the point they break. I used to run 8 turn single motor and would go through a set of brushes in about 2 battery packs (6 cell NiMh). Since you are using Lipo your burst currents will be a lot higher and you are probably eating brushes and overheating the springs causing them to sag which reduces the pressure on the brush, not to mention heating of the plastic endbell.

yes it will run, if its not worn out.

87/17=5.12:1 what is the gear ratio in the diffs?
