Hey y'all, watch this!

DON'T BE STUPID!!! Use a vessel rated for the pressure and application. A commercially-made air tank isn't that expensive. Any vessel rated to hold air will have a coated or galvanized interior. This prevents the moisture in the air from rusting it out from the inside, eventually causing a failure. It will also be manufactured to more exacting standards than your average FDS can. In other words, IT WILL BE SAFE!!!

BillS, that's NOT a good idea. Pop bottles are not made to withstand the pressure, I don't care how much tape you wrap around them. They may have weak or thin spots that will blow out. An expolding pop bottle with 100 PSI in it will DESTROY the plane it's mounted in. I hope none of the pieces hit anyone. I hope the pilot is not bent over the plane when it happens. What's next, BillS, baling wire to hold the wings on?

People, Jeez............you spend hundreds, if not thousands, of dollars on a plane and want to penny-pinch the most important things. Things that may cost you the plane or your health.

Gasoline in pop bottles from pe, and now pressurized air in a Right Guard can...Gawd, I'm glad some of you guys don't fly ay MY clubs!!! Y'all keep this up and we'll find out just how good the AMA insurance really is.
