The FingerTech 'Viper' Combat Robot Kit V2 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. 

The kit includes a JST-to-9V Adapter cable so you can power it with a 9V battery instead of a lipoly battery. Battery is not included!

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.

Great bot especially for someone just starting out in the hobby

Love the bot! I had no problem whatsoever (other than handling small parts) assembling it. Currently, I'm having to research how to get my controller to navigate the bot the way I want it to (right now it's not very intuitive), but it's fabulous.

Not bad, feels a bit underwhelming

It goes together well, metal and motors are good. The wheel and coupler mechanical system is weak though. They are designed to take hits, but are made of a soft foam. Also slides along the front lower face, no bearing or even plastic to minimize friction. Overall a low level design. I upgraded the wheels and threw on some UHMW, now its alright.
