It puts out 3HP at 24V but weighs less than 4 lbs. The price reflects the CNC aluminum can and the use of Neodymium magnets. My BattleBots team used them for a spinner-type robot back in high school. These motors rock! The downside- your batteries will need to supply 100A to realise the 3HP rating. I suppose you could mount a 3F car audio capacitor in there to help with acceleration....

How I'd love that motor.
It spends at 6k rpm though, so I'd need this too.

And that I most definitely can't afford!

3HP @ 6K is too fast???!!??

You could go the cheap route and use a couple 750 sized boat motors. A significant gear reduction would be necessary, but I'm pretty sure planetary gear boxes are available.

Have you seen these? ScooterSupport.com They have 36/48V 1000W models; 4" diameter, 6" long, 11 lbs. , ~$160.

That would be nice. I'm tryin to go really easy on the wallet though. Over the last 2 months ive spent about $2000 on rc's and when you're 15 that's a bit too much. :)
