You're allowed to mount them on the siderails, but I'm not sure about the actual outside of the track.

Not sure about the benefit but I don't see anything in the rules that would prohibit it.

Actually, I would be careful about doing this - the rules say that you can only let propellers and their casing extend outside the rails, so putting magnets on the outside would probably be a violation.

3.e refers only to the vehicle not the track.

Excuse me, I misunderstood the question...then, I would assume that you be allowed to do this, but as joeyjoejoe said, there wouldn't really be any benefit, so far as i can see. You can't have any part of the vehicle on the outside of the track that external magnets would react with, so...

I wonder if it is an attempt to prevent/limit side rail contact? If so, I'll save you some time.... It won't work.

But, who knows, it might be some clever idea borne out of a need many of us have had. I'd hate to stifle any creativity. I think it is probably too late to get a clarification on this though.

Does the Cage around the propeller count towards the 20 cm max height?

Our B team used side magnets on the track and they didn't get penalized. The only effect it had was to speed up the maglev. I think they got like 2 seconds with that on their runs with a 1.955 kg vehicle. And also, the vehicle itself could move without using the propeller, it just needed a small boost at the beginning. If you're good at the test, you can get away with a 2 second run with a near 2k vehicle mass, but a terrible time score, and still place, just that you wouldn't place 1st.

Wouldn't it probably be safer to make a cart that clocks in at ~10 seconds?

To anyone using ducted fans in their vehicles this year, where are you purchasing the fans from? My teammate and I have found that ducted fans are sold out, discontinued, or simply unavailable from almost all retailers.
