I just happened on this post doing a google search. I also was sponsored by Tom. I raced in mostly Michigan sponsored by him and Riders Hobby Shop. Raced 10L and 12L on carpet and of course dirt in the summer. That was the big deal up North waaay back then. I would let Tom know what type of track, gearing etc. and he would make me a motor. Usually we would give it away as a door prize after the race. It was great advertisement. I still have a few in storage. He was a great guy, but sadly passed away of a heart attack. Dang I miss racing R/C cars. I sold parts at the races and have tons of stuff in storage, some day I'll drag it all out and have some fun with em.
