    The Outboard Motorglider

    I had a ridiculous idea the other day. I was thinking about the ever increasing cost of general aviation, and what would be the cheapest way to get in the air. Ultralights were the obvious answer, but those have there own issues. Many of them aren’t trailerable, so you need to either rent a...

    Airplane Wanted Hang glider wanted

    I've been on the lookout for a hang glider, or even parts to one, preferably anything that still has a sail. Any type is fine. If anyone has one they'd want too sell let me know, thanks!

    Build plans for GOAT or other similar Sailplanes

    Hello, I am here to query whether any specific build plans or part listings have been created for the GOAT ultralight sailplane besides the technical drawings by Mike Sandlin. I have asked a similar question before but figured i needed to specify more on this topic. Besides that, I was also...

    Part 103 low speed ultralight glider design (wing)

    I need ideas of wing system for ultralight glider (such as Chanute, EasyRiser or Primary Instruction Glider) (may be biplane) low speed (25 - 40 hm/h) , weight of glider < 40 kg). My idea is next: biplane (wingspan - 6m, wing chord - 1.2m), S1210 airfoill...

    Ideas for joining UL tube ladder wing spars at splices.

    I'm drawing up a fat guy Sandlin glider in SW. This will be what I call the "BUG 5" as it is a derivative of the BUG4. Sandlin's drawings call out the main spar tubes as having a splice at the outer flying wire location (1 inch OUTBD of that location to be exact.) He carries the bending and...

    Improving VNE of a glider for high altitude flight?

    Hi! So I have this idea of building an electric motorglider and flying it very high (75-90000 ft) at very high TAS (about 300 kts). At the current stage, I am thinking to retrofit an existing high-performance glider with an electric motor and batteries. While researching the feasibility of...

    3D printed fuselage exterior surface, reinforced with CF inside

    Dears, i do not know if that topic has been touched before, and i would appreciate your thoughts/suggestions. My apologies as well if this is OT. I'm here talking about a tailless glider project, but at the moment, i'm concentrating on a RC scale version. I'm on my way to finalize the design...

    Greetings from an aspiring designer!

    Hello everyone! :) I have scored thousands of hours in WWII aviation combat games over a past few years and I got hooked forever... Since then I've been learning, building and flying model airplanes (crashed a lot of them) and now comes the moment of truth: can I build a real airplane? I'm on...

    Hello Everybody

    I'm a hang glider pilot. It's what I can afford for flying.Wanna build a Ligeti Stratos-based footlaunch soaring platform. Wortmann airfoil has too high of a stall speed for safe footlaunch. HELP?! I'd remove the powerplant, shroud, tank, most of the landing gear (go to single wheel with a...

    Howdy! Building a Primary Glider

    Hello! I've got a group together that's just purchased the plan set for the Sands 1929 replica Primary Glider and the materials for the wing ribs and tails. All of us have various building skills, but this will be our first full sized aircraft project. Has anyone here had any experience...

    Basic Aerodynamics Question

    Looking at Gottingen 535 airfoil data: There is data point for C.P. (Center of pressure?) at 92% of chord from leading edge at -6 deg, and the C.P. curve is extended to -150% of chord from leading edge. So how is the center of pressure not on the wing, off in space so to speak, or what does...

    Another Air Loads Question Wing Drag/Stress

    All the wing loading calculations for stressing the wing (at least those I have found) do not figure the wing drag as a loading condition. Is this because it is less than torque loading, or in the case of the glider wing tip landing forces? Am I just not finding it or is it not done for...
