    Is there a cheapest/lightest/simplest wing structure other than aluminium tube and fabric?

    FWIW - Over half of the lines do not have turnbuckles.

    Yellow Pine, for the most part. I grew up with a guy whose family ran a creosote plant, Most folks call then telephone poles, or utility poles. The originals were alongside railroad tracks with telegraph lines. Funny how that works...

    @Rhino "No trees were harmed in the transmission of this message. However, a rather large number of electrons were temporarily inconvenienced." I call BS... Trees were slaughtered and cooked in Creosote for the sole purpose of electronic communications...

    Chihuahua is too lean and stringy...

    Not foldable, as far as I know. Just keeps the solid pieces in compression and the cables in tension. Has been tested at something like +1-2G and -1G. I'd have to test it way beyond that, but schools have tiny budgets for experimentation.

    Even worse... They didn't use locking nuts, or pre-stretched leader, so they played Hell keeping tight. They thought they had "turnbuckle creep" but testing the turnbuckles didn't show that. smdh Some people don't have the sense to come in out of the rain, or ask for help. I could've told...

    Beer is a solution... and that's a scientific fact.

    Tensegrity wing with cap-strips as formers weighs about half what a normal wing does. Instead of steel cables, use an Aramid Fiber 'rope'* for tension (~15X stronger and lighter), then use wooden dowels as the strut pieces, or (even better) possibly CF wrapped wooden dowels... *UHMWPE (ultra...

    Howdy and welcome. I prefer Brisket, but it sure is getting expensive, these days... @Victor Bravo Diabetus! New diagnosis for me. Had me in the hospital for a few days. Now I'm Type II with insulin injectors.

    Old-school Ball Magnetic Compass Question

    Thank you. Hadn't thought of that. Your observation has made the difference.

    Old-school Ball Magnetic Compass Question

    I did say I could use a refresher course. I'm quite certain things have changed considerably in 40 years. That said, down here, the rule of thumb is: A: How's the weather? B: ____________________ (current weather report) C: Wait a while, it'll change. If weather was really so predictable...

    Thank you. I have never heard of Stratux, or the Avare app.
