I went on VEX to look at my options for gearboxes, and now I'm stuck. I found these gearboxes online, and I think they would work well. The only problem is that I have no idea what gear reductions I should buy. Basically, I want it to be two speeds, one for driving fast, and one (more importantly) with a lot of torque to push other bots around. What's your opinion on what I should get?
And thanks in advance to anyone who posts an answer
