blimp help Answered

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

i was thinking of using screen also but you might need something lighter but im not sure

I thought of that project too. My take on it was to use a balsa stick and hack apart servos as the motor and speed control. put a small prop on the servo motors. 1 to lift, 2 parallel on booms for forward and steering. Mount helium balloons on the balsa rail. cheapo blimpo. battery must be light. lipo are 4 volt. might work.

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.

the blimp/dirigible is almost complete

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.
