    Varga RMI-1 X/H - almost the first production turboprop

    I wasn’t expecting the hopes of a production-ready turboprop to go back this far, and from Hungary of all places. To be fair, it wasn’t ready but you have to admire the ambition. I’d love to know more about that engine to see how it stacks up against future successful designs.

    A Fisher Koala and a Tall Pilot and a Four Stroke Engine and Cheap Fabric Covering Question(s)

    Hey all, a friend of mine is going to go look at a disassembled Koala in a couple weeks and because I made the mistake of saying another low power low buck flivver would be fun he asked if I wanted to go half in on it. Sure, I’m up for adventure, but… 1. Is there any hope for a tall guy to...

    The Legality of Logos?

    I know we have engineers in this group and literal rocket scientists, but what about lawyers? There’s something I’m curious about: if I were to have an antique airplane, or replica, or period correct home built, what happens if I put some still-existing company’s period logo on it? If I had a...

    Wood Monocoupe Replica?

    A friend sent me an ad for a wood Monocoupe replica project today. While the pictures and description are awful and there’s no way to tell scale, it’s clear that the structure is all wood and the tail feathers look to be the shape of a 90 or 110. Did anyone sell plans for such a thing (like...

    The Johnson Twin 60

    Who wouldn’t want an open cockpit, pusher, taildragger, biplane twin that can get away with 30hp a side? Jam on a couple modern V-twins and you’re in business!

    Just how fast was the SR-71?

    Somewhere I have a photocopy of the SR-71’s pilot manual and as mentioned in the video it does ask that you not regularly push it harder than Mach 3.3. What the video doesn’t say is the cryptic next line that goes something like: “Higher speeds are available on orders from the Commander in Chief.”

    Anyone know offhand what a Kawasaki 440 weighs as installed on an airplane?

    Britain's Top 10 Most Beautiful Aircraft

    Not my list, and I haven't even watched it through yet. I wonder what nine he puts up before the Spitfire... Edit: my blood ran cold for a second in that Hawker Hunter footage. The voiceover was talking about the Hunter’s unique “blue note” but I bet the pilot was experiencing a little brown

    Ross RS-1 and RS-2L

    I came across this today, a neat little pre-war two seat parasol. In a lot of ways it reminds me of the 40hp parasols that came before it (Eaglet, early Cub, Zephyr, etc.) and I suspect Ross was intending to refine their general concept to something lighter, simpler, and more compact. He got...

    Santos-Dumont Demoiselle

    The little Demoiselle has been on my mind for the last few days so I’ve been doing some reading. It’s not that I’d fly a faithful replica but I do find the early airplanes fascinating, especially how they were built at a time before things we take for granted like good glue. I don’t think the...

    I’ve got your container plane right here

    At the risk of reigniting discussion on how to cram too much airplane into a big tin box, here’s the pre-1910 version of a plane that would almost certainly fit in a 40’ can: Instead of folding the wings it folds the fuselage stuff that holds the front and back bits. Get a look at the way...

    What About Laser Cutting Other Materials?

    There’s been some discussion on the forum about potential issues in laser cutting plywood, and of course there’s the current thread on troubles with a laser on aluminum. What about 4130 steel? I understand there’s a heat affected zone but how’s it being affected? Sure would be handy to just...

    Gee Bee C-8: get there in style

    Sometimes I daydream about the best airplane to cart a bunch of friends to fly ins and such. "Best" being a sort of nebulous concept that includes style in a big way because if I were to just use my brain the answer would be to buy a minivan. Anyways, I want to pull up in one of these: a Gee...

    Whitley Bomber Repair

    A fascinating look at the inner workings of a less popular and now extinct British WWII bomber: ”Repair” is putting it lightly given how many trailers of parts arrive to be refurbished. Seeing the belly reskinning it gets under the nose at least, I wonder if it landed gear up or went through a...

    Blackburn H.S.T.10

    I’ve been really getting into this guy’s YouTube channel lately and this morning came across this obscure one-off Blackburn: What I think is fascinating about it is they never flew it. Not once. Blackburn got busy doing other programs and while not directly stated I think it was recognized...

    Models Begging to be Scaled Up

    I know these threads come around every so often but now that single cylinder four stroke aviation conversions are becoming a thing maybe it's time that the subject took another lap. What non-scale model airplanes seem like they want to be scaled up to carry a person and turn heads at next...
