    More information about "Beautiful wooden propeller to suit Rotax 912UL or man cave"
    For sale. I'm doing this for a really great price for forum members, but the proviso is that for that price it is definitely pick up only, southside Brisbane. This is a P prop. Made in South Africa. This is their website: http://www.p-propeller.co.za/ This is a beautiful wooden propeller. 72 X 48 two blade. This design was first tested on a different aircraft to mine but broadly similar to mine. Mine is a Bushcat. What I didn't realise though, is that the other aircraft must have been a 912UL with a 2.27:1 gearbox. Because when it came time test fly mine (2.43:1 gearbox) it could only manage 65 knots and the engine could redline on takeoff. I've since replaced it with a more suitable, but less elegant looking propeller. This prop was removed at 21.4 hours. It's a pity as it is really lovely. Comes with the spinner and front plate. And I'm throwing in a superfluous to me hub adaptor with one doover missing. So if you have a 2.27:1 gearbox or a mancave that needs jazzing up, pm me! Note: you will have to do your homework about whether this propeller suits your needs. Just in case I have trouble attaching pics, here's some links to pics of it installed on my Bushcat

    That was the point of that air duct. They had fitted a new induction system, presumably replacing the carby.

    Lycoming 0360. Not sure how you came up with Rotec 😄
  4. danny_galaga
    Yeah, I linked to a useful article, but its in the previous page. Here it is again https://hackaday.com/2025/12/10/failed-3d-printed-part-brings-down-small-plane/
  5. danny_galaga
    Probably.
  6. danny_galaga
    Not random at all. I wondered if there might have been a small engine fire

    Some good follow up info, from Hackaday, of all places! https://hackaday.com/2025/12/10/failed-3d-printed-part-brings-down-small-plane/

    Which is, of course the whole front end of my aircraft 😄

    Is that fibreglass?
  10. danny_galaga
    Good point. I'm pretty sure I've seen fibreglass (GRP) shrouds etc in engine bays. They are combustible. But would probably burn slowly, could be why fibreglass is allowed?

    If you've seen how course something like a pla print is, you'd see the resin will permanently bond to it. But if course you can do the other way and lay up INSIDE the print.
  12. danny_galaga
    Agreed. You could actually lay up on it, and just let it become part of the structure.
  13. danny_galaga
    Yes, I actually mentioned earlier I had made a pla part and painted it. Then thought leaving it in the sun would dry it faster. Warped in less than an hour 😄 And now for ultimate thread drift, the part in question, a custom controller for the Sega mega drive pinball game, Dragons Fury. The eyes are the flippers, 'nose bone' is PAUSE/START and you rattle his skull for tilt ☺️ The base plate warped in the sun, but I managed to straighten it up enough with a hair dryer.

    It's a little puzzling, isn't it? There's a lot of skill designing that. It seems incongruous that the same person didn't take into account the heat range. I can think of two scenarios. Either the file was sent off to somewhere to print and they misunderstood the brief, or else maybe there was an engine fire or something that heated it up way beyond reasonable, with fire somehow extinguishing itself when it crashed. Although having just said that, with engine stopped you'd think the fire would be less likely to go out, not more 🤔
  15. danny_galaga
    There are of course different materials and methods. So maybe a 3d metal print would work. No idea what that would cost though. I've only used pla and abs. I left a pla print id painted out in the sun to dry the paint faster. It warped within an hour 😄

    Plane totalled, landing short of runway.Pilot only minor injuries. A good reminder I guess that it gets toasty under the hood! https://www.bbc.com/news/articles/c1w932vqye0o
  17. danny_galaga
    I doubt that any B 17 has done 92,000 hours though. And it wasn't pressurised. Obviously you'd still have to watch for things like corrosion of course but in the grand scheme of things there's a lot less to catastrophically go wrong.
  18. danny_galaga
    I think the gist of it is that it's better those parts fail, than the whole wing snaps in half. Clearly, in this case it still ended in disaster but in general the idea makes sense. There's only so much you can plan for
  19. danny_galaga
    Totally. How many litres a minute would it be pumping? It's going to be an instant fireball with no damage to the tank.

    https://www.reuters.com/world/china/cargo-plane-engine-accelerated-before-fatal-hong-kong-crash-investigators-say-2025-11-19/ One thrust reverser not working, which apparently is allowed. But on landing, that engine accelerated. A question for all you big boy pilots, how much of the reverse thruster aspect is automated? From the view of an ignorant like me, it sounds like that engine was just doing its job, just that it didn't 'know' that the reverse thrust mechanisms weren't in play

    A brief video from Juan Brown, who coincidentally flew C130s in the National Guard. He points out it looks like the #2 engines propeller seems to be missing.

    I particularly love the 'fast forward ' feature that projects where they will land 🙂

    Analog nav computer for Soyuz missions. This is just fantastic 😊 Ken Shiriff does great write ups of interesting tech. I can't follow most of this, but I know some of you will. Follow it or not, this is EM porn 😊 https://www.righto.com/2023/03/reverse-engineering-globus-ink-soviet.html
  24. danny_galaga
    Exactly. In fact, we are slipping it into the SIDE the wind is coming from 🙂
  25. danny_galaga
    I don't know what that means. Like I say, the mnemonic works for me 🙂
