How long can you do this for without causing any damage?

You know, I've actually been trying to figure out why backdriving the motors generates current to turn the system on. I haven't been able to figure it out though. The MOSFETs have diodes, but they're reverse biased, so any current going through them would be in the wrong direction. The other thing is that at some point, the power has to get to the RC to turn it on.
But to answer your second question, we had someone pushing it through a parking lot one time. By the time it got to it's storage location, it had turned itself on. The backup battery was maintaining the RC. It also smelled funny, like burning electronics. But, it still worked fine. I wouldn't advise doing it though.
