Really need some help With robot

Hello i know what im making is not generally a fighting robot but im building it along the same grounds and using abit of rex's workshop tutorials to help me along my way abit. What im making is a heavyweight bot that im goign to attach a snow plow to the front and use as a robo plow when the weather gets bad. Rex show how to use windscreen wiper motors for the power but i dont think this will be up to the job for moving snow, what does anyone recomend. Also I need a speed controller that will go with my drive system can anyone point me in the right direction thanks for anyones help

You may need something a bit beefier that Wiper motor for a heavyweight, try getting hold of some wheelchair / invalid carrige motors. As for a speed controller a sidewinder would be good enough for the job or a wotty. Or for a cheaper option but less control which may be good enough for your application get some 4QDs.

I have 2 x 4qds for sale at a reasonable price !200 amp versions.
and an rc interface board to connect them to a reciever.
let me know if your interested.
