Scratch-Built RC Hovercraft

RC Hovercraft built from scratch, mostly of spare pieces of foam. The skirt is made from garbage bags. It has 14 one-inch diameter holes around the bottom. The lift fan is actually the case and fan from a computer box fan, with the original motor and wiring torn out. The fan's shaft is attached to a 7.2V motor that supposedly was for a cordless drill. Lift is powered by two 7.2V NiCads and the rest runs off a LiPoly.

My apologies if the music scares you. :/

ok but what exactly did u use for the remote control and fan system

[highnoon3777]

It's in the specs at the end and in "more info." I was extremely cheap and still have over $200 in the electronics. If you must build your own, go to bphobbies and look at the airplane kits. Then buy everything but the airplane and put it on a hovercraft instead.

Scratch is a rare commodity, and building a hovercraft from it tends to get expensive!

hi what other materials can i use instead of the ones listed and what would be the most cheapest option cause im planning to build 3+ for testing purposes and science fair

[highnoon3777]

Cheaper than garbage bags, foam, and duct tape?

J/K. Depends on what you're testing. Really cheap would be no thrust (lift only) and using a wire to transmit all the power and control inputs.

How is your skirt attached (Is it a solid bag that covers the whole underside, or is it just a ring around the outside), and what does the underside of your hull look like?

[highnoon3777]

Duct tape. :D The underside is solid (no holes) and matches the top, except it's smaller so the top overhangs about 2in all the way around. The skirt is a ring with holes on the bottom and fills with air from between the top and bottom.

It might work better to have holes in the bottom instead of the skirt though.

I built an rc hovercraft for a school project, see it on my channel...

Sweet music

Parallel. Lift is a 7.2V drill motor. One battery lasted 4min and got hot. Two bumped it up to 8min and only got warm.
