Crabfu: Kyosho made a snowcat-type vehicle called the Blizzard in both an electrical and nitro version. The electrical was either dual motored or single motored. I believe the singled motored one was clutch powered. It is no longer in production, but it and its parts occassionally come up on Ebay and some vendors may still have a few. Good Luck and keep up the great work!
