We have a 25:1 gear ratio (two 5:1 stages) on a CIM for the flinger. We wanted to see what would happen if we use two CIMs with 20:1 for more speed and torque, but we didn't have any 4:1 planetary gearboxes.

We actually rebuilt the arm on the third day to be more rigid, but I suppose it could be damaged in a collision. We haven't tried.

The pressure to the pneumatics that raise the arm is limited by a regulator to around 30 psi or so to conserve air, but even at full pressure we don't tip when lifting the arm. Sudden acceleration with the arm raised makes us tip slightly, though.
