Are multiple switches allowed? One per motor?

As many switches as you want is fine

Looks like there's a FAQ for Hovercraft (pretty sure it's for Hovercraft) posted under Astronomy.

Has anyone taken a look at this website, or ordered anything from here? I just stumbled across it; haven't thoroughly checked it out yet.

Most of the axial fans that build a high pressure seem to be "Dual Fan" with 2 sets of fans. Is this allowed, or does it violate the one propeller rule? Are there better options?

Thanks.

This unit would be considered as 2 fans thus you would not be allowed any other fans. Yes there are better options and they aren't too difficult to find. Rather than looking for units, think about what application would need a fan with a pressure. I salvaged mine from a unit meant for a common purpose (which I will not reveal)

Hi..i am a new user here. As per my knowledge since that listing doesn't provide the important spec of static pressure. But you mentioned you were having trouble interpreting the clarification. I assume you are asking whether the example you found on Amazon would be allowed. While this is not the place for official clarifications, I can unofficially say that yes, those types of fans are exactly what the language in the clarification are referring to.

New user to this forum. Working to get ready to run this event at an invitational.

Can anyone provide info on how to economically buy or construct a photo-gate system (including related software that would work with a laptop or tablet) suitable for use with this event? The ones I see online are close to $200 with tax and shipping and that's not in the budget especially since I'll need 2 of them in order to run 2 simultaneous tracks.

Thanks for any help.

They are expensive! I'm sure someone can post a DIY guide on making your own with some inexpensive laser pointers and photoelectric components and programming skills, but, there's a good chance you're as short on time as money ... Suggestion: ask any physics teachers you can find if they know where you can borrow some. If you email the host school or coaches from participating schools, chances are high someone has a set sitting in a closet somewhere.
