The Cyclone 2 was the design to commit to a small run of 500 units to donate to the First Robotics Challenge as a competing component. This design focused on eliminating common failure modes seen on the previous versions. Featuring a single motor, a simplistic gearbox, and the new anti-detensioning rail system that eliminated the de-spoiling problem when improperly handled.

The design was locked-in and local manufactures in Massachusetts were ready to initiate mass production but due to a skeptically high bill of materials price from the gearbox, plans were halted in fear of existential expenditures. Gears must be eliminated
