nope i dont know how to weld at all steel ladder frame? polycarbonate would be no good?

i thought a Sabertooth dual 25A speed controller, would that be able to supply 2 drill motors each side, so 4 all together. i was planning to build it on plywood or something first before i built it properly.

no youve been very helpfull thanks for your help

the drills from argos would be more than powerfull enough. either get them or the identical motors from robochallenge,depends if you want to save time ripping the drill apart.
building it on plywood is a great idea, done something simular with mine (although i did it because i was bored waiting for parts).

also as relentless said, check build diarys and threads in the featherweight section, you will learn alot from other people asking the same questions that you are.
