Re: CIM Motor Sacrifice

Today we tested an RS 775 into a CIMulator with a 10 to 42 sprocket reduction (#25 chain) to 8 inch wheels. Gear ratio of 11.3, calculated free speed at tip of wheel of 40 ft/s. The wheels didn't appear to spin down very noticably on shooting the ball, but we don't know yet exactly what the exit velocity was or where we are for making some of the shots we need (top goal from key, half court, etc.). We are sticking with the FP/775 substitution plan, and at worst might need 4 of such motors. Hoping for only needing 2. It's too important to keep our CIMs in the drivetrain.
