Hi tifosi,
The Solarbotics motor that Ken is referring to you may know as the BWA/Beardog mini motor. It's the mabuchi 030 can motor. It just took the F-1 racers in the U.S. another 10 years to find them. They are still week on torque, but Al Penrose is doing some research on some with stronger magnets that should solve the problem. (yes Al's still doing things, just behind the scenes, with limited internet access).
Tony, how did I do the helmet? it's just a Beardog helmet hollowed-out with a LeMans Miniatures face, the secret is to use magnifying goggles so that I can see what I'm doing, and of course a great Yorkshire white rose decal.
