    The AFB (Amazing FleaBike)

    I'm no engineer, but this seems like the best solution as it follows the basic rule of making stuff thickest where it needs to be strongest.

    The 'daydreamers' thread...post your craziest designs and concepts here

    Something like that already exists.

    Bourke engine viability?

    Right, that's why I have the oil flow inside the piston and crosshead rod to get to the rings.

    Scratch Built Radials

    Consider that a radial two-stroke that uses a simple crank-mounted blower for scavenging doesn't need to run the fuel through the crankcase, so it can use conventional lubrication. If done with ports for both intake and exhaust, there will be some oil consumption, but it cuts down on the number...

    Scratch Built Radials

    What method of induction and scavenging does it use?

    Bourke engine viability?

    I've seen a guy on youtube doing a test run of his bourke. That sucker sounded ANGRY, but it ran quite well as far as I could see. As Topaz has pointed out here and other places, You also have to be a good businessman to set up production of a new engine, which has tons of overhead costs just to...

    Very low aspect ratio planes?

    Well, prone pilots are like pusher props in that they do great if you get them just right, but suck if you don't, and getting them right involves compromises that may be impractical depending on the airframe. Anyhow, twin facetmobile. Though this one one is technically a smoothmobile. Forward...

    No wonder it’s called a Flea

    I guess this is why some of the guys here prefer motorcycle-type aircraft seating. He's one missing panel away from Flintstoning that thing.

    Looks a little nose heavy. I'd stick a canard on that. Everyone remember this bad boy.

    A FrankenFour Inline?

    Good. Needing belts or gears would defeat the goal of simplicity. Stick 6-8 cheap little cylinders on there and oh sweet lord all that blessed torque.

    Pop over to Luft '46 - WWII German aircraft projects All the weird WWII designs that were never made.

    A FrankenFour Inline?

    If it were driven directly by the crank, would it deliver enough air?

    Very low aspect ratio planes?

    In some cases yes, but remember you also get a light cantilever wing with plenty of internal volume to put stuff in to reduce parasite drag.

    A FrankenFour Inline?

    I'm thinking a radial two-stroke with a positive displacement pump to create crankcase pressure would be the ticket because you could use a lot of small cheap cylinders from yard equipment.
