It was -30 out, so I only ran for a little over 6 minutes, but I'm confident that lipos are just fine in the cold and the MMM's conformal coating over the PCBs is adequate enough protection. A body helps keep the snow down a lot, but my mounts are all broken. A bit tough to steer with your chin, but this thing is a BLAST to drive on the ice!
All I ever wanted was an honest weeks pay for an honest days work.
