Too much torque?

[Ctrl Alt Delete]

How much torque can we have on the motors? I'm looking for a specific gear ratio here. We keeping burning out our clutches. Is there any suggestions?

Just from experience a gear ratio of 1:3 is enough to round out the clutches in a drive if your drive has some momentum behind it, and you try to reverse it. I also made an arm with a 1:5 gear reduction, and I broke the gear teeth before the clutch rounded out, so it kinda depends more on the amount of momentum your mechanism has.

From my experience the clutches really don't work like they're designed. While they typically fail before the internal motor gears strip, they fail by rounding out (not how a clutch is designed to work). I've found a decent workaround. If you put a drop of super-glue in the clutch connection that takes the short axle, you can reduce the strength of the spring (by either cutting it down or weakening it by over-compressing it) so that the clutch will actually slip internally. I realize none of this answers the original question, but at least when the clutch slips internally, it doesn't lead to failure of the part.
