    Another Ultralight-ish High Wing Idea

    Thanks. I'll test one to see if it's adequate. If they're no good I'll use them on, well, my wheelbarrow. ;--) Rob

    Another Ultralight-ish High Wing Idea

    I ordered some $20 4.00-6 wheeliebarrow wheels and tires. They should be here in a few days. Thought I'd waste some time drawing them on the model to see how bad they look. They look kind of goofy but I like it. Had to get all three the same size because I'm cheap. They weigh 5 pounds each...

    Another Ultralight-ish High Wing Idea

    Over the holidays somebody broke into my shop and built this... Whoever it was, I hope they come back and finish up. Maybe they'll do the back half of the fuse too. Rob

    Another Ultralight-ish High Wing Idea

    Tacked up the cockpit floor yesterday. It doesn't look like much but I gotta start somewhere. I'll try to get the top stuck together today. Then I have to jig the top and bottom in 3 dimensions and tack the sides on. Rob

    What scale and composition of your favorite Warbird would you purchase?

    A lightened full-scale Me 109 with a LS motor could be built to weigh half of what, say, a G6 weighs, maybe less. It would have a landing speed much slower than the originals. I think this would mitigate the ground handling problems of the originals to some extent. Of Japanese fighters the...

    What scale and composition of your favorite Warbird would you purchase?

    Agree. The J22 is a beautiful airplane. I stumbled on it a few years ago when I was looking at a bunch of light fighters from WW2. A lot of these light fighters are really cool airplanes. Build a full-scale but lighter version of this airplane with a smaller motor and you'd have something...

    Raptor Composite Aircraft

    Wasn't it fore and aft flutter that ripped off the wings of early Grumman Avengers? I think it was due to the ailerons not being balanced vertically. It took them a long time to figure it out because nobody thought the wings could oscillate fore and aft. There is a video somewhere of it...

    Another Ultralight-ish High Wing Idea

    To be honest I'm not a big fan of high-wing airplanes. I prefer low-wing ships. But a low-wing airplane would be more complicated than this simple machine. Just building a wing with dihedral adds a bunch of work/parts. The main motivation for me is the simplicity of the concept. Also of...

    Another Ultralight-ish High Wing Idea

    Thanks. And you're right. There's a lot of curvature to the top of the wing. I haven't given any serious thought just yet to an actual hinge design. I'll think about it and look at what others have done in the next few days. It is nice to be able to sketch these ideas on the computer...

    Another Ultralight-ish High Wing Idea

    I really like the Sky Pup. But I live in North-Central Kansas apparently right where all the big weather fronts like to meet up and hang out. The wind never stops blowing pretty much from any direction it feels like. And rarely right down the runway. ;--) Rob

    Another Ultralight-ish High Wing Idea

    The Backyard Flyer has one additional small bolt about which the wing pivots. The 4 bolts that retain the wing on the Backyard Flyer are inserted vertically and are in tension rather then a more conventional setup where the bolts are in double shear. Very little difference in complexity...

    Another Ultralight-ish High Wing Idea

    What do folks think of this? I don't really need folding wings but it would be nice to fold it up and stick it in the corner when not flying it. Would make it easy to trailer too. All folded up it's 17.5 feet long and 8 feet wide. The "swing wing" center section (like the wing on the...

    Another Ultralight-ish High Wing Idea

    Not much to share about the wing right now. I'm not certain yet what it will be made of (metal or composite). If I go with metal it will be pretty standard--sheet spar web with extruded angles and flats to make up the spar caps and metal skin on the leading edge to make the d-tube. The aft...

    Another Ultralight-ish High Wing Idea

    Makes me wonder how women learn how to fly... ;--)

    Another Ultralight-ish High Wing Idea

    Good question. I wasted, er, I mean I very productively spent, a lot of time on this problem. It seems that unless there is some kind of pretty hefty beam connecting the nose, tail, landing gear, etc. that passes beneath or on either side of the pilot, there will be some members to be squirmed...
