This is my beetleweight:


And the scorpion motors would be for my featherweight. I will plan to use 75mm Robochallenge wheels, a gearbox made by erm...me, and it will be controlled by an Arduino Uno and an Arduino Proto board onto which i will solder my own motor control circuit. I know you keep saying to go brushed, but only 2 brushed motors i know of will do the job: ampflow motor (too big and expensive), and 2 Astroflight 40 cobalt motors (extremely expensive). If you have any ideas of any brushed motors, please tell me.
