For the small ones there are several companys with kits, altho most of them are autonomous.

I'd recommend starting with a basic R/C "flight kit" (on the ground frequency of course). That would be a transmitter, receiver, battery pack, and 2 or 4 servos. Servos are easy to "hack" and make into strong pushing gearmotors.

For example, Servo City on line sells a full kit for about $115 that would get you going.

Also wanted to post a great link from Pete Smith, of Team Rolling Thunder, who sells combat kits and also has a tutorial on hacking drill motors.

Missed your post until now, sorry.

I'd go to either robotcombat.com or inertialabs.com and check them out. For speed you need to figure out how fast you want to go (I usually design 1.5 seconds to cross the arena) and torque depends on if you are a pusher or weapon platform. Pusher = 7x torque for the weight class, weapon platform about 2-3x torque.

Example a 1 lb antweight should "push" 7 pounds (assuming perfect traction which you'll never get).

More help if you post some more info on your design. Also, we can hook you up with a local builder or event to provide even more help.
