I had an idea by the cylinder drive. I would have a small pipe that is above the front axle, and would be powered by a motor width wise in the engine. By doing that, the rubber band would always say vertical. Although it would take some time to build, I think that is the best bet. I have pulled apart both a VCR and a R.C. Car, but I don't think either have a good gear system.

Have you looked at all the drive parts available for RC cars?
