    Treated wood could be as strong as CF?

    Sounds exciting. The downside of this is that its going to cost more than either CF or steel. It's the way of the world I guess...

    The JK-2 Nano

    Hi guys, Have you seen this one? The JK-2 Nano. Beautiful little thing. Almost makes me want to have one. The only real thing that bothers me is the high thrust line. From the manufacturer's FAQ: Can you tell me why I shouldn’t be concerned about the high thrust line? We have done in...

    The AFB (Amazing FleaBike)

    Topped it off with my wife's hairdryer. Five minutes and the ply was completely dry. I'll leave it in the former overnight though.

    The AFB (Amazing FleaBike)

    I think I've nailed it. I built a D-tube bending jig yesterday, and bent my first D-tube this morning. Worked like a charm! LOTS of boiling water painted on (mainly on the outside surface) with a broad paintbrush. Then gently pulled the ply into the former, while painting on hot water. In...

    For those with an interest in the Goodyear inflatoplane.

    Hi, Why use Yahoo? I followed your link and got pages and pages of bogus news stories - nothing about your plane. Yahoo is a terrible choice for a platform. Even Facebook is better. Best of all, why not create a dedicated thread right here on HBA? Duncan

    Aaargh! This CAD stuff is doing my head in! I think what I'm going to do is to cut the formers as drawn by DevWing, and then overlay a strip of 1.5mm ply on the aft section when I need it. Easy Peasy. I've just wasted a pertfectly good morning slaving over a hat laptop when I should have...

    This is what I'm thinking also. I'd use Sketchup's offset function, which easily would do this, except that Sketchup doesn't do curves - it approximates curves with multiple straight lines - some of them quite long. I'll see if one of the other 2D CAD applications might help... Cheers Duncan

    OK, I need some advice. Here is the supporting structure to ensure alignment as well as the 1 deg dihedral for the centre section and the 3 deg dihedral for the outer panels. All this was produced by DevWing CAM (very nice software, by the way). But my problem is this: The ribs have a 16mm...

    What Did You Do To Save General Aviation Today?

    I've not been following this thread, but it seems to me that the best way to "save" general aviation, is to (1) produce a plane which any wage-earning guy can afford and (2) market the hell out of it. Price-wise - the cost of a 2nd hand family car. Marketing-wise, social media blitz. Spend a...

    Took the boss' daughter for a flight. Yeah, right. Had a good time, did you? Ha ha.

    From the title of this post, I thought you might be delving into James Joyce's Ulysses... Thankfully not.

    Hi, No worries at all. A digital HM293 is indeed an enticing idea, and certainly doable. And potentially profitable, given the popularity of the design. Well, "popularity" is relative, of course - the Flea segment is tiny within a very small segment after all. Everything from "The outer wing...

    The AFB (Amazing FleaBike)

    Finally, I spent the rest of the morning making the jig for the wing panels. Each panel is only 1250mm wide (front wing) and 1000mm wide (rear wing). I've built in two aligning holes in each rib so that I can thread the ribs onto 25mm stainless pipes, which will be held in place by the jigs...
