Do you have a website link for those drone fans, in regards to where to buy them?Birdmusic wrote:We're using drone fans for both lift and thrust, works pretty well, but i recommend you experiment.geniusjohn5 wrote:What type of fans should I use for each lift and thrust? If possible, can anyone provide examples of those certain fans(like pictures, websties, etc.)?

The biologist speculates, "What's the meaning of life?"
The physicist asks, "In the universe, does matter really matter?"
The chemist replies, "I shall find solutions to both questions."

Are these types of fans ok? If they are, are they effective?

Re: Are these types of fans ok? If they are, are they effective?
I think the static pressure for the fan you linked is about 3.19 mmH2O, which is about 31 Pascals. If you're looking for a fan that can lift the hovercraft, these'll be too weak (pressure-wise)geniusjohn5 wrote:Are these types of fans ok? If they are, are they effective?

Re: Wood or metal studs for the track?
At every competition I went to last year, the same metal studs were used. We ended up buying the same ones for practice.DrDaveV wrote:The rules state "standard 2x4 framing studs recommended." I see a lot of metal studs in pictures from other competitions.
Which is most common at competitions, metal or wood?
What are most people using in practice?
You should ask people on your team who competed last year. I doubt proctors would change the boundaries if they already had materials from last year.

Re: Hovercraft B/C
Which batteries are better to use? Double AA or 9v?

Questions about wires
What type of wires should I use for building the Hovercraft?

Re: Questions about wires
Depends on the batteries you're using. Just match the gauge of wire to your batteries and motors and you should be fine.geniusjohn5 wrote:What type of wires should I use for building the Hovercraft?

Question about Lift fans
According the Science Olympiad website for Hovercraft, it says centrifugal blower fans should be used for Lift. Can anybody show or describe what is a centrifugal blower fan? I Googled it but they were not was I looking for a Hovercraft.

Something like this, obviously with better pressure ratings.
