The drill we had was 30V from NuTool with 1.7Ah Nicads Very powerful drill.

Just been testing some cheap 18V drills (also NuTool) and stalling them on 12V gives 50Amps and we run them on 24V! Under stall it takes less than a second for smoke to start coming out of the motors. Another interesting point is the speed controller in the drill has 12-24V 8A printed on the side and testing it through the speed controller on stall gave 40Amps.

Problem with all drill motors is that they have too much power available for there size and can not dissipate the heat for long periods. When was the last time you ran a drill for 5 mins constantly reversing under load without burning it out? The trick is to make sure you dont use all that power usually by keeping your wheels spinning.

Thats right , i have a tight budget and have been thinking alot on a set of cheap 18V drills, i dont know the name of the company who made them but I will look that up.. Mark 40amp?! that sounds very much because i have been thinking on a set of electrolise speedcontrollers and they cant take that amout of amps for too long i think

Slight problem!!!!
One E-Tek...23 pounds in weight..Weight limit for feathers 12Kg (26 pounds)...Think about it!!!

Now if you want some SERIOUS drive for your feather..forget drill motors...

How about a LEM-2X2 in a walking featherweight?

How about a LEM 130 on 24v with a magnetic clutch drive system like Whipper

@ jeff - the thingaps do like nice on paper, but the only feather ive seen thingaps in had the gearboxes break and get beaten by a drill powered bot

Thin Gap..... Two x 340w(output) 12v winch motors on 24v = awesome! Only draw back is the 2.5kg each motor with the 9:1 steal planetary gearboxes.

Aaron, where did you find those winch motors? They could be quite useful to me.

Look around at your local automative stores that supply 4X4 vehicle accessories. The ones we managed to get are around $180 Aussie Brand New. They will easily drive 40-50kg around on 12v. You have to do a few mods like remove a gear reduction and make a shaft up to suit, but its simple if you know what your doing and have the tools
