    fabric on ribs with huge spacing, doable?

    Indeed that was the first original plan, it is very tempting to have a circular planform as shown :): the superiority of the low weight structure is not matched by any other planform or construction method.

    fabric on ribs with huge spacing, doable?

    Thank you so much guys for your input. You are a gem of a community 🙌 It is amazing how much research & development and design is contained in an aircraft project. Design is like 95% of the aircraft. Building it is a childplay. People who know me ask me where is the project, where is the...

    fabric on ribs with huge spacing, doable?

    The 'daydreamers' thread...post your craziest designs and concepts here

    Indeed, the wasp was the first flying jet version. I believe Charles H. Zimmerman in the 1940s was the first ever ,in modern history at least, to conceive and test the idea of using your natural body kinesthetics to control, stabilize and fly any platform near effortlessly. As you can...

    The 'daydreamers' thread...post your craziest designs and concepts here

    It is real. My first impression ever was that it has to be a fake but looking at the water spray, the handling.. it is real. Physics, at least, allowed this creation all ever since the great Stanely Hiller came up with the idea. You can buy off the shelf rc jets that produce the...

    A question about this used 582,

    Yep, indeed, there are seemingly other cheaper in-good-shape 912 engines too for equal prices! However, it seems that my big fear has just became real & reinforced about buying used engines from overseas. I tried other listings on that same trusty http://www.aerosales.co.uk/website...
