On another note, how does the CIM work? We built a transmission over the summer, where the CIM was drawing huge amounts of power, and ended up for this year with something similar to the two motor design in the white papers. Does a single CIM work? And if so, doesn't manual shifting get confusing during a fast paced match?

Back to the earlier SCS thing. It might be possible to design a "steptronic" type control that normally shifts automatically, but could be overidden for climbing, &c.

Have to check on the rotary pneum.'s thanks for the idea.

Yes, it probably is possible to shift with a servo but we wanted to get away from them. We had troubles on the drill transmisions with the number being in the right spot to tell the servos where to stop. They worked every match but they occasionaly caused us grief.

We checked the power curve for the CIM's to figure in on a good ratio.

I drive it and it isn't bad. I shoot over some where quickly and then just get into a lower gear to push, pull, climb. It really isn't bad. I was talking to our programmer about adding a new switch and a current sensor to make it auto. We might we might not. It isn't really neccesary for this game to much.(for us anyway). But back ont to topic, no it isn't hard on the driver (me).

I am lost with the whole SCS thing since I saw the first post about it.
