My mrt speedo seemed a bit temperamental tonight, for no apparant reason during a race it would seem to go into a 'safe' mode whereby I had no steering or throttle. The lights were still lit on the speedo and if you turned it off then back on it was fine again, after another couple of minutes the same thing would happen again. Anyone any ideas on why this would happen and how to correct it.

I am running a 19t modified brushed motor in my cyclone moorespeed.
