That's because you are in division B.

I lost my rules for B division MagLev vehicle. (2010) Just one question, what is the maximum hight and width (if there is one) of the vehicle? Thanks a bunch.

Anyone have suggestions for propellors?

Right, I was hoping for a little more detail . There's a lot of plastic propellers out there, and anything aerodynamics is way over my head.

We're trying to experiment now but the propellers we have don't all have the same hub size, which is slowing us down quite a bit.

I would use three blade plastic propellers, and try to glue more plastic pieces to them to increase surface area.

The cheap little 2" plastic props seem woefully inadequate for accomplishing anything useful. Speaking of which, anyone have a reliable method of attaching a prop to a shaft that's too small? I tried some adhesive stuff that seems to be holding, but it probably wouldn't survive transportation.

I haven't tried it yet, but I think you could do it with some rubber tubing that just fits over your axle. It's elastic, so it wouldn't have to fit perfectly.

Where did you get your cheap plastic props?
