    Tandemwings and CG range

    Focussing on tandemwings lately. And ... it still puzzles me. Tandemwings are labeled as being able to take more CG range, but ... Flying Fleas are very sensitive to CG placement. A bit too much backwards and you get in trouble. The Stileto by Ligetti also dropped due a CG too far backwards and...

    Tools for easier building

    I added a page with some homemade tools i thought to be too cool not to show. I recall that lining up the wing under a drilling machine took me a long time to get those long holes in the spar perfect. Aleksey showed me a tool that can do it in minutes. WHY DIDN'T I KNOW IT Clever tools - Nest...

    WIG (Wing In Groundeffect) without the need for large engine. My proposal. Too crazy ??

    I am thinking a lot about WIG lately. And i noticed that a commercial WIG is still not going to happen. One of the reason is the need for a large engine to generate enough thrust to get the WIG out of the water. Once in the air it needs less power to stay in the air in ground effect. But it...

    any single surface BSLD wings known?

    Hello, i was wondering ... did anybody ever think about single surface BSLD flying wings? A friend is trying to create a nano-trike (below 70 kg) in Spain. Could i suggest a very low weight BSLD by using a single surface (as many nano-trikes are single surface)? And ... how can one create...

    BEACHDRAGON, a fun project. Low aspect ratio-BSLD-ridge soaring.

    My mind connected a few ideas. Might be fun. Fun on the beach while ridge soaring the dunes. Not a paraglider, but a inflatable hangglider with stick control. What if we combine a rather low aspect ratio with a thick root chord with the technology used in recent surf kites? And using a BSLD...

    Two engines close to each other = still possible as "single engine" regulation?

    Been tinkering on a idea. Was starting to think about something similar to the Cri-Cri engine layout. Two tiny engines very close to each other. My idea might even be closer to each other than Cri-Cri. Left and right of vertical fin. My question: you need twin-engine license to proof that you...

    a worldwide event just for ultralights. THIS WEEKEND.

    If you have a ultralight airplane and can fly this weekend. You can be part of the WUFI-event by just taking a picture airborn. Read more about it in the article of Dan Johnson. You can read the entire article at : WEBSITE DAN JOHNSON click EXPAND POST to read the entire post and to see where...

    Dan Johnson writes: WUFI this weekend. Worldwide Ultralight Fly In.

    This weekend, if you have a lightweight airplane, go fly and join the WUFI-event. Dan Johnson writes about it. I am super pride to be one of the "inventors" of this event. I stopped active aviation a few years ago. But WUFI still carries on. Might be that this year ... it will be MUCH larger...

    Easier mould-making for a ultralight Low Aspect Ratio

    Just trying to find a way to make a wing in composites for a motorized, ultralight low aspect ratio. My goal of this discussion here: finding a way to make the composite wing with as easy to make moulds. I had very bad experiences with endless sanding of moulds that start with hotwired or CNC...

    PAL-V. The flying car. Progress towards testflight.

    The PAL-V project. I have been following this project from the first testflight of the prototype. I am a supporter. I still am. But i saw some negative comments lately from non-believers. “It is a scam, it hadn’t flow yet.” “Those specifications are bullsh@@.” “Two engines and one prop. Yeah...

    Super basic retracting front wheel

    I am in search of similar systems. Something super basic and light to have a retracting front wheel. Steering is not needed. This example came from the Facet Opal, a very light but speedy flying wing. Extra difficulty: It has to fit in between the legs of the pilot. So ... compact too. Mission...

    Flight stick mixer of Little Bird by Milt Hatfield

    Who has more clear pictures of the mixer Milt Hatfield used in his Little Bird. It is a low aspect ratio airplane with elevons. I see the mixer at 08:18 in the next video, but i cannot see any details. Would like to know more about how it works. Looks really really very basic. that is why it...

    Flying wings / The importance of where to place rotation point of the airfoils

    Yesterday i was mailing with another member about hinge lines in projects. And he had a problem in the past. He designed a BSLD* flying wing with a straight leading edge, but he noticed that it was hard to place control surfaces because there were no straight lines at the trailing edge. He made...

    How to hinge and seal a elevon in a very thick airfoil of a ultralight

    Been thinking lately about a low aspect ratio like Arup, but a really small version. I hope to get it stored sideways in a garagebox due to a rotating elevon which flips the entire trailing edge over the wing. Installing a hinge at the topline seems like easy to do. But ... i will get a huge gap...

    Car-stuff to create lighter skins for composite wings

    I had this idea for a loooong time (wanted to use it on the DragonWing), but i never used it for real. Now i want to know what you are thinking about it. Problem was: how to keep the skin of composite wings as light as possible. Aeriane made the SWIFT composite hangglider have a white skin...

    Choucas, a modern evolution of the Fauvel unswept flying wing

    This French site shows a lot of nice info of how they made this composite flying wing in unswept configuration. Looks a lot like a design by Fauvel. Choucas Here a few pictures of that website.

    My old drafts for inspiration / Flying Wings

    I added a page in my website. I might trigger the creative minds. It are old to very old drafts of me. To see the page go to Draftbook / Flying wings - Nest of Dragons Here a few previews. Some are using controlsurfaces like the Mitchellwing U2.

    FLYING WINGS / Tractor VS pusher / Marko's vision

    Hello, i just want to share why i once changed my own project from Pusher to Tractor. The reason was this reasoning of Marko Stamenovic, a rising star in flying wing world in my point of view (just ask Albion Bowers to say i am right) Moving engine to tractor position -> Engine mass is at...

    Honeycomb structures. How to do it?

    Hallo, i am trying to find as much as possible info about this building technique. It kind of sounds like building a airplane LEGO-style if the parts are CNC-cut. But ... i guess there is more to it. I am trying to collect as much info as possible about it. The good stuff and the mistakes...
