Drills

Dont know if you have read this already but after skimming over the Mini EV Overvoltage topic on the US Robot Fighting League forum it confirms that Mini EVs dont like being overvolted and at 18v you would be pushing it because a hard impact at that voltage will break the brush holders on the motors unless they are well supported.

Also you might want to read up on the Mini-Walt its a Mini Ev combined with a 18v DeWalt drill transmission making a combo more faster, smoother and cooler drive with neutral timed and more torque compared to the 18v DeWalts running on 24v . The page also provides some good insight and modifications to improve the Mini Ev motor.

James Cooper sells some very grippy blue wheels, and modifys them to screw straight onto drills. Many roboteers have had these made for them and not a single one has been unhappy with their performance. these wheels are used by ploughbot, venom, micro-maul, razer, warhead and many more.

well worth checking out

I agree competely Grant.

I bought 4, cost Â£3 each for the wheel and a further Â£3 each to take their weight down to 140g.

Very grippy and good quality.

JH-Q ...... I bought some of those wheels from Clas ohlson in Sweden when I visited their store in Insjon earlier this year. They will fit straight on to your drill motor gearboxes. They are very grippy too.
