    LiteFighters: P-40/P-36 and beyond

    Thanks much for sharing, Wil, really cool to see a pic like that with a personal connection. I’d love to do a replica of my grandfather’s WWII plane but even at reduced scale it would be a challenge. He was a U.S. Navy pilot flying a U.S. Coast Guard PBY Catalina. (This is not his actual...

    Cable-braced airframe design resources?

    Sorry but I don’t understand what you mean.

    Cable-braced airframe design resources?

    Does anyone have any suggestions for books (probably going back to the 1930s) that cover detail design of cable-braced airframes? Pros and cons of different cable bracing configurations, attachment fittings, carry-throughs, etc.? There must be documents out there but I can't recall seeing much...

    Lower rpm 2180

    I can't see that operating a VW engine at a lower cruise rpm with a larger prop is likely to do any harm to the engine though obviously the prop clearance could become an issue of the change is significant. Off the top of my head, the VP-2 specifies a 60 x 30" prop for an 1835cc engine and a...

    Flying wing

    I'll take Koen's seated approach with transparent covering and a bubble for your head over a prone pilot position every single time. I want to keep living and avoid paralysis.

    Burtz Engine

    Air-cooled?!? The traditional Pietenpol pilots wouldn't know what to do with all that visibility and their faces would be cold(er). ;-)

    thanks for adding me.

    Sorry, George, but who are you asking and specifications for what?

    1/2 scale warbirds

    Sorry to hear about your crash and injury, glad it wasn't worse, hope you're back to 100% soon.

    Burtz Engine

    Very cool, the engine conversion part always scared me a little on the Pietenpol, I may have to dust off my Air Camper plans and take another look!

    Concepts only: Doodles without numbers

    Koen, Going back to these sketches, I wonder if using elevons would make more sense, both because it would provide washout when needed to prevent top stall at low speeds and because I wonder about the effectiveness or responsiveness of spoilers. I really like the idea of lightweight low AR...

    Flying wing

    Check out posts by Koen (nestofdragons) in this group and visit his site. Concepts only: Doodles without numbers (and many more) https://www.nestofdragons.net/ Personally, I’d avoid prone pilot position as I’d much rather crash feet first than head first.

    In with a bang, out with a whimper

    Oddly enough for southern New England, I grew up shooting and my grandfather was a class III dealer. Fourth of July with the Thompson was a family tradition. I shot most U.S. rifles and carbines from the trap-door Springfield through WWII and today own an M1 Garand, M1 Carbine, M1917 Enfield...

    In with a bang, out with a whimper

    Sadly, no, not in over 20 years. We used to shoot one every July 4th but Gramps sold his M1A1. No kidding.

    Ah yes, pylon turns with purpose! “Any place. Any time. Anywhere.”

    In with a bang, out with a whimper

    Marc, are these comments based on some knowledge of the testing involved or just speculation? The video I have seen of gun runs showed accurate fire in short bursts, which seems to be how that sort of gun needs to be used given the rate of fire and light airframe. A production combat aircraft...

    VW Heads for Aircraft - Billet

    Is there some reason you couldn’t run side valves with straight pushrods acting on little bell cranks?

    Between-the-war aircraft replicas

    Personally I just have a thing for the interwar, fixed-gear light racer-based or racer-like fighters. Don't even get me started on the Caudrons. This, for everyone else since I know Svetlio knows it well, is the B.35/2.

    Between-the-war aircraft replicas

    Thanks, Svetlio, for your reply. Oh well, the fixed gear, elliptical wing B.35/2 was my favorite anyway, but it doesn't have Bulgarian connections.

    thanks for adding me.

    Welcom, Jan. I am a fan of the earlier Tips designs, so pretty!

    Between-the-war aircraft replicas

    My understanding was that the B.35 existed only in prototype form (three total) but twelve production Czech-built B.135 fighters were in service with the Bulgarian Air Force as advanced trainers and occasionally saw combat. The D.520 is also a great choice, quite pretty.
