hey guys, im thinking of building my own petrol rc tank, im fine with all the servos etc... was thinking of using a lawn mower engine

the only thing i cant get my head round is power to the tracks, i cud easily make both or one work but i dno how about making them work independant

would it be a case of a limited slip diff? it seems a bit .... complicated

basicaly i just wanted to know if anybody had any ideas pictures or plans

thanks in advance
hope to see you on here, i will be documenting my build if i go ahead and will post
