Vipers will be shipping with 0.50" thick wheels/hubs until the 0.75" thick ones arrive late November.
If you've added the Charger option, we will hold the order until chargers arrive late November.
Once this batch runs out more will arrive sometime in December.
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.
- 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.

-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.
