How long are you wanting the runtime? A 12ah sealed lead acid should get you by for most scenarios.

Definitely! That was actually one of the inspirations for mine. I found that link shortly after starting my own. It is a great read.

you should check out this project http://members.shaw.ca/sonde/
the guy has some useful experience in this,

the issue of gliders going over there VNE is about flutter, normally this is an issue with the ailerons and the twisting action they impose on the wing resulting in the oscillation you saw above, but any flexibility in the structure will eventually lead to flutter, can have some impressive effects in armature rocketry though these guys are probably also encounter compressibility http://www.youtube.com/watch?v=D-d_tN5NNPM

Though these dynamic soaring gliders seem to go pretty fast without such problem sttp://www.youtube.com/watch?v=S0gnnBGlTdI

additionally at 60,000ft the air is about 1/10th of the density at sea level, so your stall speed will have increased by a factor of 3-4 you just have to make sure this doesn’t exceed your VNE, Spead of sound at 60,000fh 295m/s so your unlikely to encounter any compressibility issues…

Im building one of theseand am curious how big of a battery i will need. Im skipping the head unit and just using a 400 watt Fosgate amp that ill jack directly into with my iPod. Any ideas?

You’re a hero, what you’ve done is beyond impressive. Respect.

Dude, from the report i have of your actions on that day, seems to me that you are in fact, one of the most badass people I have ever heard of.

I can only hope that should I ever be in such a situation, I would act with even a quarter of the caring, expertise and levelheadedness that you did then.

Someone needs to invent a website i can send you beer via the internet with already.

Much respect from York, UK.

Hey there: the narwhal bacons at midnight. And the narwhal says you did real well in that tornado.
PS: good luck in the competition.

I am building one of these and would like to keep the car receiver I am using as the source/amp completely inside the enclosure. The receiver I have came with a remote. Does anyone know of a IR extender that could be used with a car stereo receiver to allow me to use the remote with the extender “poked” through the outside of the cooler?
thank you in advance!

Nice Job! My friends and I wanted to do a project like tis for the 4th of July. Could you please forward the details of the project? Thanks!

Awesome! I just started laying out a project like this the other day and figured I’d Google just in case anyone else had built one. Very cool! I think I’ll incorporate your idea of using the covered switches, that’s a nice touch. I’m also going to attempt to put in a small speaker and Arduino sound board to incorporate sound effects from the Apollo missions, complete with the Apollo 11 count down and “We have lift off” clip. My young cousins will love it. :)
