This is the second version of Total Recoil, which uses two powerful springs to flip its opponent into the air.  The springs are tensioned by a brushless skateboard motor driving a specially shaped cam through a 64:1 gearbox. Total Recoil gets around with a highly efficient brushless drive system. Its chassis was designed in CAD, laser cut from a special hard grade of steel called Hardox 450 and then welded together. Total Recoil was built and is driven by Richard Cartwright.
