The Viper Combat Robot Kit comes with everything you need to get started in combat robotics.
- The custom-formed 6061-T6 Aluminum chassis has plenty of strength and space for additional components and upgrades.
- A 6-Channel radio transmitter and receiver pair leaves four channels free to add any active devices you desire. (Optional, in case you already have a radio.)
- Two FingerTech "Silver Spark" 33.3:1 ratio gearmotors with 2.25" Snap Wheels provide both speed and pushing power.
- Two FingerTech "tinyESC" speed controllers translate the radio receiver commands into motor movement and provide 5V power to the radio.
- Polycarbonate combat armor keeps the components safe.

The Viper kit is fully intended to be sawed, drilled, modified, and upgraded. Recommended for ages 10+ (6+ with a parent).
Its base weight is only 313grams (11.0oz) leaving:
• 141grams (4.97oz) for additional parts if entering the Antweight (1lb) weight class
• 1049g (37.0oz) if entering the Beetleweight (3lb) weight class. (The Viper is mainly run in the Antweight 1lb class)

-One or two 9V batteries (two doubles run-time). We recommend Duracell Procell (PC1604) for over two hours of run time and bursts of 12A (using 2 batteries). Procell's can run a HXT12K servo at 1.5A continuous (while driving) for well over 15 minutes.  (Robot matches are 3 minutes each.)
July 17, 2015 Upgrade: The Viper Combat Robot Kit now comes standard with a rechargeable 7.4V Lipoly battery! This changes some of the kit specs, so old specs will be shown in (red).  We have a few of the 9V version left - make a note if you would like this version.
