rc motor for gocart

[Sinewave]

anyone know how much torque these big outrunner rc motors can put out?

if i were to make a go cart with four 12 volt 100ah car batteries, would there be enough torque to push it or would it burn up?

id aim for a top speed of around 45 mph with reasonable acceleration, doesnt have to be neck snapping...but a bit of oomph to it would be nice.

thanx!

Sure. Google "RC motor go kart"

This has been done before and it works well. The motor and controller would cost a bundle, though. I bet $800 for mtoro and ESC would be the minimum to drive a kart decently. There is a guy on youtube that has 3 outrunners with 3 ESCs that runs awesome!

If you gear them down enough, the big ones should be fine.
This guy used three Turnigy 80-100 motors on a common shaft, and it definitely looks like he's got more than enough power.

sorry for my slow reply guys.

thanks for the links and reassurance that the motor will be powerful enough...

i was just a bit hesitant because of the extreme weight of four 12 volt 100ah batteries.

the link that was given appears to be using litium batteries, anyone have a link with someone using regular old heavy lead batteries? 4-8 of them?

thanks again.
