COMPETITIVE OUT OF THE BOX

Unlike our SSP kit, this bot doesn't pull its punches. Weapon first, aggressive, hard hitting, and fast. The DRV kit is easy to repair, but a challenge to master. Soldering skills are a must, and common sense safety is paramount. This is no toy, it can cause serious injury if mishandled.

Support our small business, and American manufacturing!

DRV kit frames are CNC Machined in-house in New Hampshire using U.S. sourced materials, and American machines. We use an AvidCNC Router from Washington and Airweights vacuum table from Colorado. 100% of all design work is done right here in the USA.

The SCARAB Drum
S7 Tool Steel Teeth

Hardened S7 tool steel teeth take the hits and keep biting. Built to survive impact after impact.

Aerospace Aluminum Hub

A machined aerospace-grade aluminum hub keeps the drum light and rigid.

Integrated 2222 Brushless

A powerful 2222 brushless motor lives inside the drum itself. Direct drive, maximum spinning energy, no belts.

260 MPH Tip Speed
260 mph

All that energy spun up to weapon-class velocity for the concussive hits that decide matches.

Peak Weapon Energy
>950 Joules

Roughly equal to a 10-pound bowling ball thrown at 46 mph, or a 256 mph baseball pitch.

Drum Dimensions
65 × 100 mm

65 mm diameter (2.6 in) and 100 mm wide (3.9 in) for a wide, hard-hitting contact face.

Precise Low-Speed Control

AM32 ESC firmware on drive gives smooth, precise control at low speeds, so you can line up the perfect hit instead of fighting the throttle.

4S Power System
4S

A 4S (14.8V nominal) architecture feeds both the weapon and drive with the headroom to push hard, match after match.

Built To Take A Hit

The DRV is built to survive the worst the box can throw at it. Tough where it absorbs impact, stiff in the frame.

CNC Machined UHMW Frame

The frame is machined from solid UHMW for maximum toughness. It flexes, absorbs impact, and shrugs off hits that crack rigid materials.

SRPP Composite Plates

The lid and base plates are high-strength SRPP composite, better known as Tegris, for an exceptional strength-to-weight ratio and serious impact resistance.
