What did you enter for voltage/current draw? The motor you want can only handle 350W. That's less than 1/2 HP. There's no way it will handle 4000W. 350W is in brushed 540 motor territory. I think you'd be lucky if you got 20 mph with that setup your looking at. I'm all for the conversion, but you need to do some more research before you buy. I would want at least 1000W in that truck to get good performance out of it. 1000W is easy: 20V @ 50A. etc. You should shoot Aqwut a PM. He has a lot of experience with big, powerful conversions. Good luck!

The thing I dont understand is. I own a currie 400w 24v scooter. I can wheelie with ease on a full battery and can hit 21mph. Im dropping 50w and upping the voltage by almost double. This would be plenty of power for my 1/5?
