Electric motors will also act as a generator too if you spin the armature without applying power. It is normal. All moa's have done this. You will notice the lights on your esc light up as you do this also.

Not all MOA's will do this...Losi axles with the MOA kit comes to mind (this this is true of any worm driven MOA...)

Simply because the motors can't overcome the friction of the worm gears. Take one of the motors off and spin the wheels and it will turn.

Actually it's because you can't turn worm gear axles by hand.

...try that sometime and let me know how it goes (hint: it has nothing to do with friction)
