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" gearmotors with 2.25" Foam 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.

Required Items (Not included in kit):

These items are not included in the kit but are required for use.  They're optional as they transfer from bot to bot and some people already have them.  

If starting from scratch you'll need to order a Transmitter/Receiver and a battery option whether 9V or a lipoly and charger. 

  • Transmitter and Receiver: are required for operation.  If you do not have one Please add the T6A Transmitter/Receiver item to your cart. 
  • Battery:  The Viper kit can be run off either a 9V Battery or a Lipoly battery.  We recommend using a rechargeable lipoly but a JST to 9V adapter is included with the kit if you prefer to use 9V.  
  • Battery Charger: If using a lipoly battery pack a charger is needed.   We use the B6 50W Charger.  It's an all in one charger that charges up to 6S to grow with you as you build more bots.  

Optional Weapon Upgrades:

When you're ready to add a weapon the following upgrades pop right onto to your existing Viper chassis and require no machining or soldering.
