Hmm! Will have to try that on home turf, before running into the same situation in the wilds again!
Thanks!

So again, if you run out, shut everything off, turn it back on, and then trying moving at a very slow speed. You might be surprised how far you can go. Think of it as "limp home" mode. If you try going faster, the controller will just shut it down again.
