I'm not a tech head when it comes to electrical motors, but others on here are. I do know that if you attach the leads of the mechbox on reversed, you'll instantly blow your fuse (or heat up your motor if you're not running a fuse). Heating up your motor that way can't be good. ***I can only recall getting the wires reversed in while the AR latch was in place...so I can't say 100% that an AEG motor won't run in reverse. I'll try later if I remember, I'll have 3 rifles on the bench tonight.
Some MOSFET units have Active Braking, where a very short reverse pulse is sent to the motor after the shooting cycle is complete. It's not long enough to reverse the direction of the motor, but it is strong enough to "freeze" any overspin.
www.extreme-fire.com has a video of this (or at least they used to).
