I RapidShare'd the torque specs for the 2.5" cim. I'll see if i can dig up my copy of the 3" cim torque curve. Post with ?'s or //s.

Hmmm...

To make this whole process easier, I just use JVN's design calculator. Go under the simulator section, enter your motor specs and the robot stats (wheel size, friction, weight, etc...) and it will provide some wonderful graphs about the performance of your drivetrain.

It can also do a bunch of other cool things.

Check it out if you're ever designing ANYTHING on a FIRST robot that has a motor and reduction; it will help immensely.

Thanks JVN
