For a system such as this, you really need to model and do the math for YOUR system.

The lever arms vary from team to team, the CG location varies, etc... For everything. To say team X had a ratio of 50:1 so we can use that is not going to work.

You need to look at your rotating joint, and figure out what torque the CG is causign around that. That number will vary throughout the rotation. For conservative gearing, through gearing have that equal 20% of the stall torque, that assures it'll be moving. If you gear it near stall, you'll just sit and pop breakers.
