* Requires modifying the original plastic armor, or buy a pre-cut set here: Vertical Spinner Top Armor / Front UHMW Armor

Specifications:
Weight: 124grams (4.37oz) - added to the base kit, the total weight is 419g (14.78oz) with a 2S 300mAh lipoly, or 426g (15.03oz) with a 3S 300mAh lipoly.
Drum diameter: 61.5mm (2.42in) tooth-to-tooth
Voltage: 7.4V - 11.1V. The 7.4V battery optional with the Viper base kit works great, but a 3S lipoly will give your weapon extra oomph! We don't recommend running this off a 9V battery, as it cannot supply the current needed for fast and repeated spin-ups.

Requires:
- Weapon Safety Lock
- Phillips screwdriver #2
- Threadlock liquid
- Electrical tape, zipties, or cable-ties

Safety:
- As with anything related to combat robots, it is potentially dangerous to add a spinning weapon to a robot. Never power up the robot outside of a safety enclosure. Always use a safety lock and follow proper activation procedure. Visit our Safety Information page for more information.
