I am attempting to build 5 aircraft flown by a local by the name of Art Hartman. This is the second. It is a 1907 dirigible and I only have 1 photo and 1 dimension to go by (approx. 38 feet length) Thought about vacuforming it, even made an attempt at it using a couple of sweet potatoes as a form, but didn't like the results. 2 - 1-litre soda bottles are the basis of the airbag. Building the framework out of .030 styrene. Will be rigging it with 2# test fishing line as with the flyer I built earlier (see separate post). The rope net will be made from plastic onion bag material sprayed with a couple different brown/tans.
