I've been watching the show for awhile and recently decided to try and make my own. On doing research on their site, i saw they reccomend getting boards/chips and all this other electrical equipment. The handyboard that one site is offering looks promising, but is like 300 bucks. Then i thought about all the old r/c racecars i have laying around. I was wondering if anyone made a battlebot out of an old race car board? I would change the motor to a stronger one, and if i need a second board to control something else (i.e. a weapon system) i could use a different controller/board from another r/c car i have laying around. makes sense in my head but wanted to know if this was tried before i get all deep in it and find out my plan was stupid to begin with. Thanks!
