i am attempting to make a R/C blimp. i don't know what to cover it with. would like to have some help for making the frame. i was thinking about making it out of screen but I'm not sure. suggestions?

I'm tring to build a blimp that will retain it's helium for a few days. It won't need to hold a gondola or anything. It will tied down.

just use a mylar balloon and strap on the motors.

use chicken wire and some screen it has worked for me in the past
use piano wire for the frame. glue it together with a soldering iron. you can bend it into perfect circles. for the covering, you'll need something airtight to hold the helium (or whatever you use). try canvas, and seal it with a thin layer of flexible epoxy.
another thing to remember. the helium is NOT under pressure. it basically has helium inside the tank rather than air.

the blimp/dirigible is almost complete
Instructable? I hope so...

could screening (used for windows) be a good frame?

You can go to an aviation store and they have a paper material that would be perfect for this. Sorry I dont know what it is called.

Didn't I see PSci do something along these lines recently (or am I delusional again?) ?

. I'd use Mylar for the covering. Not sure about the frame.
Definitely mylar for the skin (it's one of the few membranes that will retain helium for more than an hour or so), and if it's a blimp it won't need a frame - gas pressure should hold it in shape. (If you mean the frame of the gondola, though, I would either use bamboo for cheapness, or most R/C modelling shops will sell thin carbon-fibre or plastic tubes suitable for the job.)
