Not knowing what the game will call for this year, I'm just hoping to see how flexible our motor usage can be. Any general, or specific, comments on the big CIM will be greatly appreciated.

Thanks,

Ben, as I'm sure you are familiar with our bot's setup I'll leave out some details but attach this pic.

Anyways, we used 2 of the big Cim's on the shooter wheel mechanism for the sole purpose to get the wheel to have less time before it was back up to speed.

It worked out great, and we blew one motor at Battlecry, and you could definitely tell the difference when we went up one match with only one.

The time in between going from post-shoot speed to gaining full momentum in the shooter wheel was dramatically reduced with both motors.

As far as drive, we used the regular Cim's this year so I'm not sure how the new larger mini-bike motor Cim's would have worked.
