Does anybody have guess about that come-along handle under the wheel? Was it an oval racer, and that is a left turn aid?
I doubt it would be fast ,unless it was on ice or hard packed snow ,and that prop looks like the lift prop I had on a racing hovercraft ,not much shape to it probably moves a relatively high volume of air .It does not look like there is a reduction unit on it and I doubt there is enough engine power to really get that thing moving .
if you guys are a little interested in small airboat drives ,have a look at the “Bandit” air drives made for Jon boats .
