Note that the propeller shaft is cylindrical, not "x" axle-shape, so
friction is much greater than standard axle.
It worked reasonably well, even with no lubrication and old batteries. I
reckon with some lube, and maybe even a more powerful motor, it would work
really well.
Oh, and running the axle vertically runs better than horizontally, so even
better for hovercraft 8?)
