Propeller or jet to push an in-line skater?
Orval Fairbairn o_r_fairbairn earth_link.net wrote:
.... The model airplane guys have a very small (about 15" long, 5" dia) turbojet that they use on scale jet R/C planes. It costs about $3000 US. How much for maintenance and fuel? Is it louder than a gas powered weedeater? Just curious.
