Well this was the grand project for my class this year. 30 percent of the mark. Make a sled puller to pull 35+ lbs. The sled had a rubber bottom at the front, and a wheel and axle at the back, and had a small motor to drive the weight forward just like the normal scaled ones.

After we are done with it at school, were sticking a chair on it and riding it around!
My parnter and I, spent about 100 bucks on bearings, 5/8 axle, starter motor off a V6, tires and a few other things.

She tops out at about 35-40 KM/H or about 21-25 MPH. She pulls real good too
And I had to make it a TRIKE! :TrikesOwn
My teacher got vids as well. We pulled it inside on a cemnet floor and it ripped, then we took it outside on rough ashphalt and ice. She killed it there too.
BURNOUT!! She lights em up real good, esp. with weight on her.
P.S notice the black marks! lol

Thats awesome! :TrikesOwn


Is there a remote mechanism to start/stop the starter? Or do you squat on it while it pulls?

We got her wired up so theres 2 wires about 3-4 feet away. Then you just cross them and off she goes, Brakes? pfft brakes are not touching the wires and letting friction take over.
Need to operate that far away for safety purposes! damn school! lol Or else there would be a seat on it!
