The CS3 kit has a 0.25" Polycarbonate chassis and is powered by two Speed 550 motors that power all four wheels. It was developed as a 12lb Hobbyweight fighting wedge/brick
and had some success cumulating in the prototype CheepShot 3.0 winning the 2006 national championship. A local high school bought three of the kits to use for a "Real Fighting Robots"
summer camp. The original investment was recovered in less than two weeks of half day classes. The Schools kits are now in their sixth year of use and showing little signs of wear.
When the kit was
developed back in 2004 it was more than capable of facing any of the weaponed bots around at that time. The sport has moved on and the rapid increase in effectiveness of Drum and Bar spinners has meant that it no longer
is tough enough for combat but it is still plenty tough enough for use in "Bot Hockey" and Sumo applications
