    Concepts only: Doodles without numbers

    I have an account with X-Plane. Over my head, but I with I could use it. I use MS Paint because I was fairly well skilled at it before my strokes, which screwed up my short-term memory. That, in turn, makes it difficult to learn new-to-me stuff.

    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...

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

    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.

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

    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.

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

    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.

    Old-school Ball Magnetic Compass Question

    Only if it needs to know its own location. As a means of scanning ahead and using the Imaging for a display, there is no need for the gyro. My goal is something simpler that can merely display the area forward, including any detectable horizon. Like watching TV, I can look and see the horizon...

    Old-school Ball Magnetic Compass Question

    So, a pleasure craft, according to you is local flight only. If you're enjoying the ride you have to be stressed-out about everything every second of the flight and so forth. Yet people have made incredible journeys in ultralights without following your advice. Uhmm... Sailplanes don't...

    Old-school Ball Magnetic Compass Question

    Weather prediction is tricky enough subject that some of the best are wrong only 20% of the time. I've been driving by a decent weather service, in a downpour, when they announced there would be no rain. Being friends with the fella, I called him and suggested he look out the window... In a...
