OK this is my first forum. I have been following instructables for a year now but have never joined. I love DIY stuff and everything like it. I recently went to sacramento for thanksgiving. On the way back my faimly and i started to have one of those random road trip conversations. The topic of people who attach hellium ballons to lawn chairs came up. There was a movie about this a while back i dont know what its called but im not interested in that. I told my parents that i would have done it if i had the chance. Then my father and i came up with an idea to make an ellite hellium aircraft. We would take away the longchair and other variables. The end product would be somthing where i would have an oppen cockpit with hellium ballons tied to each corner and two 12inch fans in the back for sterring(the fan size may change) What im asking for is suggestions for ideas what type of materials the cockpit should be the list is endless im just asking for ideas Money is not a problem i have a finacial contributer that will pay for everything After i am finished with the prototype i will make another one and then post an instructable about thank you Public Enemy No.1

You'll want something light and strong for the frame, first thing that comes to mind is carbon fiber, or fiber glass. Trebuchet03 has some instructables on making large molds and such - he participated in a human powered vehicle contest. Keep in mind that you need the really large helium balloons, and a lot of them.

The mythbusters got latex balloons from the army surplus but they broke kind of randomly. I would recommend mylar balloons, they are stronger. You would need a lot of helium. It would be a lot cheaper to build your own ultra light.
