    Of course I forgot to mention we are talking about the spark plugs in case anyone is wondering 😄

    Spark plug debate here: https://www.recreationalflying.com/forums/topic/39835-rotax-9-series-engines-anti-seize-thermal-paste-nothing/

    Here you can debate the merits. Personally, I think Rotax should know what's good for their engines. They designed them. They have by now tens of thousands of hours of data on them. To me the only thing to debate is WHICH thermal paste is a good alternative to the apparent hens teeth Rotax recommend.

    Damn, big jump in price 😲

    If you have the chute, and there's some chance you'll crash trying to land it, you might as well pull the chute. Very high survival rate and besides the airplane now belongs to the insurance company in any case.

    Who knows? It has silver in it, conducts heat and electricity. Just like in heatsinks, it doesn't conduct heat nearly as well as metal to metal, but it does conduct way better than air. You are only filling in the tiny air gaps that appear between the threads. Much of the heat, and probably all of the electrical current is being conducted metal to metal.

    I just went to Jaycar

    We don't know who's right yet 😄 But in the world of starters it's unusual to have basically the same starter built for two directions. Definitely can occur, most obvious example I remember is the Bosch car starter motor. They built a version that ran the other way for air cooled VW's. Every other one spun the same way as virtually any other car starter. But we are talking hundreds of thousands, and then millions of VW's versus a few thousand 912s. With something niche, normally you work around what's readily available. We've seen that with other peripheral parts of that engine, including the fuel pump. I wish I'd thought of all this before I put my engine in, I would have tested the starter on the bench. Now the engine is in, it's a real pain to get to. Maybe the mount was designed by someone from Alfa Romeo 😄

    Don't forget the Rotax 912 starter sticks out of the crankcase, and the f650 nestles above the crank case, effectively changing which way it turns the sprag clutch. Does that come into it? I get dyslexic looking at gears 😄 What's disappointing, if it spins the wrong way is that the f650 starters are listed as ccw. Do we know which way the Rotax starter spins? Is there no one here with a loose Rotax 912 starter they can test?

    Before you pull apart the aftermarket starter, can you check to see it's spinning the same direction as the Rotax one? I would be surprised if the aftermarket one isn't pretty much exactly the same, other than the possible direction of rotation. So it should have an oil seal, since the engines these starters go on have the same set up as the 912. That is, sprag clutch in the crankcase or gearbox, running in oil. Looking forward to more news 🙂

    Whatever the details, people smashed their heads on the ceiling. Lesson? Stay buckled up, no matter what the sign says.
  12. danny_galaga
    Yes, one guy observed that no one who was buckled in was injured. Not surprising. Like you say, every single passenger from that flight is going to remain buckled in during flights from now on...
  13. danny_galaga
    Deceased possibly due to heart attack. 6 or 7 severely injured. I ALWAYS have my seatbelt on when seated. Even loosened off a bit for comfort it's going to prevent you from smashing your head. I'm sure pretty much everyone here would too. https://amp.9news.com.au/article/7e6480ac-852c-4ca4-ae03-c58cd0cbeb25

    But back to the original question, yes Holden was definitely better than Ford 😎
  15. danny_galaga
    You missed skippys point. I almost did too. If you have exactly the same engine in two very different aircraft (say a Zenith 701 and a Sling, both with Rotax 912uls), then if one aircraft is just much more streamlined it will go faster for the same fuel consumption per hour. Then if it's going faster for the same fuel consumption, you are flying for a shorter period, so total consumption is lower for the faster plane.

    What was the question again? 😄

    I actually think he deliberately slowed down for the shit. A friend of mine regularly posts 4k footage from his racing drone, and I think that goes over 200km/h. Not saying this particular drone is capable of those speeds, but if you wanted more close footage you could use a faster drone for the takeoff sequence, and something else for other footage. You'd need to, racing drones don't run for all that long 😄
  18. danny_galaga
    I guess you didn't. A Sim would have all shadows in the right place though, they use realistic physics. If your PC isn't the latest and greatest, shadows is one of the first things to turn off.

    Yes and No. The journalist reported the correct thing, right? And then an interviewee voiced an opinion which is incorrect. Perhaps the only thing might have been to reiterate that the journalists statement was correct not the bystanders.
  20. danny_galaga
    What on earth are you guys smoking? It's not a flight sim 😆 Just some very nice footage, using drones
  21. danny_galaga
    Your ebay listing says CCW. If you are careful you can put some jumper leads on it and see which way it spins. Be careful though as it will jump when it spins. Unless you carefully mount the lugs in a vice. But don't clamp the carcass (body) in a vice since I think it is permanent magnet, you don't want to crack them. Does your old starter work at all? You can do the same with that and see if they both spin in the same direction.

    Maybe think of what things people might need in a pinch. Tyre patch kits, cable ties etc? But definitely snacks and drinks! And a toilet. If oil filters, then oil too.
  24. danny_galaga
    I have imagine this is not their first rodeo, and anything that has crossed your mind, will have crossed theirs too...

    Apparently snap vents are getting hard to get. This supplier does them https://www.plastics4performance.com/snap-vents-pop-it-vents?fbclid=IwZXh0bgNhZW0CMTEAAR0VNwzHvoAdOi7g5c3l2edpvi7nveAE7Knh_t3GNufXDM98cgnv8KoLPk0_aem_AfrUOBPFubMkDXaOb15b16WnLb0a7RWPMCarHliNi651_a-SUE-6qnePpD6paCLSYXJQR9g5JotV1BnOpXId1Hck
