I fail to see how the size of the contact patch has anything to do with the ability to catch air. Bases on what i have learned in physics, the velocity (kinetic energy) of the robot would have the greatest effect on the robots ability to get catch air.

When we ran that system, we ran it at around 6-8 fps (and yes we had 4 CIMs) and there were a few robots that could push us around, gearing up the system anymore would would only increase the number of robots that could this system around.

I am very interested in what has been done to fix this problem, it originates from the track being pushed against and out of its groove, increasing the friction to far greater than the motors can overcome. There are no visible changes to the design that would help to overcome this problem.
