    Should i run my battery till its completely dry?

    I run my batteries till the car stops moving.
    Is this harmful to the motor or the battery?
    Currently i am driving a rustler with a brushed motor.

    NiMH batteries should be used until they're dead.

    Stop as soon as you notice that the acceleration gets sluggish otherwise the battery will heat up a lot which is not good for the battery. Even better if you stop a bit earlier since the deeper the discharge the shorter the overall battery life will be ( that goes for all rechargeable batteries )

    DO NOT DISCHARGE A NIMH BATTERY PACK ALL THE WAY TO EMPTY!

    Can you ellaborate a little bit on that? Should you immediately fully recharge the NiMH's? Let them cool off for a little while? Put a half charge on them? Leave them completely discharged? TIA

    Let it cool down. Put a full charge. Leave them charged. Heck I'll be wrong probably so...

    Let it rest and cool, then put on a full charge. If they sit for a bit without use, occasionally top them off or cycle them.
    You don't want to run them down till they die, the lowest I take them down is around 1.0v per cell. 0.9v/cell is the lowest and any lower will cause damage. Plus they don't have the "memory effect" like nicd batteries do so you can charge them at any point.

    If you discharge a NIMH till dead you are in danger of the cells going to reverse polarity. I have a pack where one of the cells went reverse.

    In furtherance to a cell going to reverse polarity, the affected cell will not except a charge, it will get really hot and will start to vent.
