Over the last week I've been working on a remote controlled hovercraft!
Today I took it to a duck pond to test it out and boy does it work!
It's 26 inches wide and made of a 1 inch thick styrofoam. When the lift fan turns on, it floats 4 inches off the ground! This is actually the 9th version, I've built four other smaller ones that didn't work right. All in all this thing has taken about 6 entire afternoons. It's been a long time but definately worth it!
Two side propellers move it and the lift fan is a 5 inch, 12 volt case fan i had lying around that i run off a 19.2 volt battery. It blows A WHOLE LOT of air!
It's an awesome thing! Finally I've spent a weekend doing something other than messing with my many PC's!
