After the last thread, I deduced that I wanted to use drill motors. After experimenting with woodys calculator, and deciding that I want to use 7mm blue wheels, I hit a problem. My little combat robot would be relying on speed and pushing power. With 750 rpm drill the top speed was 30 mph - and anyway the drill was £49.99 - and I need four! So, somehow I need a way to keep the wheels the same size, but I need a cheap drill (£20 or under) with an rpm of about 1000 per minuite (planning to overvolt it by 50% on Woodys instruction).

Im not just looking to you lot because I cant be bothered to look - I have done it to death on the internet, but I was wondering if there was something I am missing, or a website that you have used before in building.

Thanks,

Alex R
