In '98, the last year we ran without gear change, we ran 4 wheel drive with about 1:5 ratio in high gear driving the 6 inch wheels. We had Skyway wheels on the rear and home made "easy side slip" wheels on the front. That gearing was about as high as would work reliably, but we were still using Tekin speed controls that would sometimes shut down temporarilly due to built in overcurrent protection.

If you are running 4WD with four Skyway wheels, and are near max weight, probably 1:6 in high or 1:2 in low would be as tall as you should go. If you are transferring a lot of goal weight to the robot, that might be pushing things.

This info pertains to using drill motors only. Also, other posters may have different opinions.
