Hey guys; When I was really young, I saw on a TV a guy who had a gas-powered fan mounted on to his back, and he could ontrol the throttle with somethin in his hand. He got on rollerblades and could zoom around a track at pretty decent speeds (30+ mph). There was no stopping mechanism.. I was wondering if I wanted to reproduce this, what would be a good motor to choose? I'm assuming some type of lawn equipment engine, perhaps a gas powered weed eater engine? And somehow mate it to a fan? But any suggestions?
