June 16: All Viper pre-orders up to June 12 have shipped!
Now two components are out of stock:
1. tinyESC motor controllers - A new batch is scheduled to arrive in 1~2 weeks.
2. The 33:1 ratio drive motors are also out of stock now and expected early August (no promises). By default, pre-orders will be held until the 33:1 ratio restock has arrived. If you would like your Viper sent with 22:1 ratio motors instead (50% more drive speed), add that note to your Additional Comments during checkout and they will be sent as soon as tinyESCs have arrived.
We will continue to allow pre-orders on the next batch of Viper kits. The dates given are best estimate, not guaranteed! (Last time the pcbs needed rework and were delayed two weeks. Unfortunately this is out of our control.) Vipers will be shipped out in the order that pre-orders were received. Purchasing this pre-order means you understand and accept delays.


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.

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. (We don't recommend running the Viper in the Beetleweight class versus 3x larger opponents!)


Dimensions:
Body Width: 16.5cm (6.5in)
Length: 14cm (5.5in)
Body Height: 3cm (1.18in)
Weight: 313grams (11.04oz)

*Transmitter and receiver are required. See the "Radio Option" notes in the Contents tab for more info.
*Battery required. The Viper can run off a 9V (disposable or rechargeable) or lipoly battery packs. See the "Battery Option" notes in the Contents tab for more info.


Add-ons:
These add-ons fit right onto the existing Viper robot chassis - no machining or soldering required!

Viper Kit Spare Parts

If the Viper is out of stock, it might be just because of one or two parts.
You can use the Spare Parts page to get everything and substitute missing parts with others.
Kit Includes:
Chassis:15gauge (1.45mm / 0.057in) 6061-T6 alloy Aluminum stamped and formed baseplate. Has mounting holes for motors, armor and add-on kits.
Motors:2x 33.3:1 Silver Spark Gearmotors
Motor Controllers:2x tinyESCs translate the radio commands into motor movement and power the receiver.
Wheels:2x 2.25x0.75" Foam Wheels are soft and grippy.  A direct hit will be absorbed and won't destroy your motors!  Includes 3mm x 0.75" Lightweight Twist Hubs and Twist Hub Key.
Power Switch:A Charge Switch that you unplug to turn on. Comes pre-soldered with a female JST connector and includes a pair of Mini Terminal Blocks for making wiring connections.
Plug has male JST end for easily recharging the lipoly battery. (Do not attempt to recharge a 9V alkaline battery.)
A JST-to-9V Battery Adapter is included for operating the Viper with a 9V battery. (Recommended during testing.)
Armor:3mm (0.12in) thick front wedge and 1.5mm (0.063in) top armor made of high-strength polycarbonate.
Screws:Four 0.125" 2-56 screws for mounting the motors. Four 0.50" 6-32 screws and six 0.375" 6-32 screws for fastening armor.
0.050" and 5/64" hex wrenches included for tightening screws and setscrews.
Instructions:Detailed instructions with many pictures and tips for getting more from your robot. (Download V4.0 here)


Controller Option:
• Transmitter and receiver are required. If you don't have them already, you can add them with the option above. "Radio Option" includes: T6A Radio Transmitter, TR6A receiver (Transmitter requires 8 AA batteries.)

Battery Option:
It is highly recommended that the first time you turn on your Viper robot is with a 9V battery. They are much more forgiving than lipoly batteries. If there is something plugged in wrong, a lipoly's power might be catastrophic, but a 9V can't put out enough current to melt anything.
• The most economical solution is our Rechargeable 9V Battery. They can be recharged hundreds of times! Make sure to grab a 9V Charger Adapter Cable so you can recharge without removing the battery from the robot!
• If you choose to run your Viper on a disposable 9V battery, we recommend Duracell Procell (PC1604) for over an hour of run time - better than every other 9V we've tested.
Your Viper includes a JST-to-9V Battery Adapter for running the Viper on a 9V battery.
[Or, a JST to Dual 9V Battery Adapter can double run-time and available amperage by using two 9V batteries.]
For maximum power density, you can't beat a rechargeable 7.4V 300mAh "Galaxy" lipoly pack. If you are planning to add a spinning weapon, you will need the amperage that lipoly batteries can supply. Lipoly Battery and Charger are available as an option above. "Lipoly Option" includes: Lipoly charger, 300mAh 7.4V "Galaxy" lipoly battery

Worth Every Penny
- 05th June 2024
The perfect kit to get started with robots. Easy to build, great instructions, and the potential upgrades are easy to find to make your bot even badder! Bought one so far for my son, probably buy another kit for myself right away.

It's a little expensive but, it is very good way to get your kid or loved one into robot combat.
Cool kit
- 17th December 2023
this kit looks awesome, but outclassed by today's kits
[FTR: Vipers continue to place at events worldwide. Just takes a bit of upgrading and lots of driving practice!]
fun

I like it because it fun
Amazing kit
- 06th March 2023
Without a doubt the best way to get started in combat robotics. It gives you a starting point to make it your own and it helps teach you about how the robots work. If you are on the fence about this kit then absolutely get it.
Looks fun
- 04th February 2023
It's expensive
Will buy eventually
- 05th June 2022
When they're back in stock I'll buy one
Great but expensive
- 02nd June 2022
This is great quality but super expensive. It worked perfectly but for $266 us is excessive.
Great way to get introduced to Combat Robotics, or RC in general
- 31st May 2022
To be honest, I've always been daunted by building a robot, even though it's been a dream since seeing battlebots on TV. I have tried building one of those kit robots as a kid that follows lines and I couldn't even turn the thing on. However, I can confidently say this kit has been easy to build and figure out. The parts I got were high quality and easy to assemble. While the controls were scrambled, I was able to figure it out with a mixer and some basic trial and error. I did have some issues fitting the wheels to the bot, but it's much easier once the foam wheels form to the hubs. Overall, this is the best and simplest way to get into combat robotics.
Unkillable

So i brought this kit to school to show off to my friends the first day i got it and i was driving around and some one landed on it after a layup and it didnt break except for the polycarbonate front armour peice on tiny peice brok

really good spinner, and highly effective
So easy, so fun!
- 21st October 2021
After attending a local event my roommates and I picked up a pair of Viper kits, with lipo and transimiter. The kit comes super well packaged with everything nicely wrapped up to avoid damage in shipping. The instruction sheets are very well printed and printed in color. (With the lipo and charger add on you get an extra sheet that shows how to set up the charger)I was able to get my bot up and running in 30 minutes. And from there I've been practicing my driving. I cant wait to go to my first competition with my little Viper!
Would recommend this product, costumer service is great
- 02nd March 2021
This guy's customer service is unparallel to anything I've ever experienced, he is willing to send free parts to fix problems walks you through what's wrong and how to fix it just all around a good guy.

The kit itself is pretty easy to put together and adding a weapon add-on is just as simple. 11/10 would buy/recommend fingertech products.
Amazing!!!
- 17th December 2020
Bought this for my sons. They play with it all the time. They've built it and rebuilt many times. The quality is outstanding. FingerTech customer service always goes above and beyond.
Great
