    This is the sort of kit I was talking about. One side effect would have to be you've reduced road clearance but on a plane it wouldn't be such a big deal https://www.heritagepartscentre.com/au/ac1151792-maxi-pump-2-with-oil-filter-mount.html?gclid=CjwKCAjw44mlBhAQEiwAqP3eViRvfIRluPrzWk3rN6rRHJdlyQMGznrXgaTe0VMluyXo2ykVjE5eIxoCITUQAvD_BwE

    Yes, and you would remember that you had to use non modified/non detergent oil else small particles would just keep circulating the engine instead of building up in that screen. I only ever cleaned my screen once. Didn't look very grotty. That either means not much wear, or a whole bunch of crap just kept circulating, not fazed by the screen 😄 You could also get an aftermarket oil filter kit. Would they be using something similar in the Aero versions do you think?

    I also believe they weren't really meant to go beyond 50,000km . Which would take a long time for the average German family in the 1930s. Probably why even into the 70s the odometer clocked over after 99,999 😄

    That's the conclusion we have come to. My battery is on the inside of the firewall. Cables go through a fibreglass firewall with grommets. Even if it rubbed through nothing would happen. Negative goes straight to the back of the starter. Positive to the starter solenoid which is mounted on the outside of the firewall pretty close to the starter and battery. The kit has you put the solenoid WAAAY over on the left side- quite a long cable run and more chance of a short.

    Have I misremembered it? I wonder what I was thinking of...

    Like I say, you regulate the output instead. If it's some sort of linear regulator, it will dump excess energy as heat through diodes (not the rectifier)

    As the op I just of something that can be a pain with VW, but not sure about Rotax. That is, one of the crank bearings, might be centre, Is a ring rather than two halves. From memory it's so onerous to try and change (the crank is pressed together trapping the ring bearing in place) that virtually no one ever replaces them. So even the fanciest souped up VW might still have it's original ring bearing. I wonder if this is the case for any of the Aero VW jobbies?

    Slip ring is on a rotor. Yes, if you open circuit a rotor you stop making the electrickery. That is a powered rotor commonly seen on stand alone alternators. And the regulator only has to govern the rotor voltage to regulate total output.On a lot of lighter machines, and my Rotax the rotor is a permanent magnet. The regulator has to control the output voltage. Not ideal, but on the Rotax it's 17 amps instead of say 4 amps for a rotor. Which isn't leaps and bounds different. Only the stator side going open circuit is going to cause a problem. For instance, disconnecting the battery while the alternator is operating.

    The AC coil doesn't really 'know' where to stop with voltage. If open circuit, and therefore no load it tries for infinity.

    Well, I would rather not have anything at all but everyone insists that if I don't have an isolation solenoid/relay then I should have a mechanical isolator. Clearly it's not something you would disconnect while the engine is running. It's for emergency use only.
  11. danny_galaga
    The isolator I'm using, yet to be tested is a small motorcycle screw type. Winding the knob out disconnects, and if you really need to you can wind it all the way out until the lead falls off.

    I only ask because an LAME apprentice was in the hanger and we were talking about it. He was pretty confident you HAVE to have on in GA, but wasn't sure about 19 rego...
  13. danny_galaga
    If there is anything written about it, can anyone point me in the right direction? Ra Aus technical manual?
  14. danny_galaga
    My isolator as it happens is on the negative purely because it was easier to install on that side. For the purpose of this thread solenoid=relay. As a auto sparky we always referred to them as solenoids to differentiate from regular (30amp 70amp etc) relays. So long as I don't legally need an electrically operated isolation switch of any sort, I'm not going to install one. If it's a legal requirement I will of course.
  15. danny_galaga
    Thought I'd asked this before, but couldn't find the thread. As per title, do you legally need one? I have a basic mechanical battery isolator at the moment. If I don't legally require one, I'd rather save the weight and extra complexity. I think when I asked before you guys convinced me about the virtue of a starter solenoid warning light so I know if the starter is still engaged. So I have that and the mechanical battery isolator .

    Maybe, but the reg/rec is electronic so in that world everyone knows that it's a heat radiator but it's easier to say heat sink 🙂

    This is going to go off track very quickly, so before it all gets shut down may I point out that there is no prerequisite for refugee to be poor. If you are escaping a war or really dire circumstances, the first people to do so are going to have money/connections. What would YOU do to save your family, or better your life? Would you stay in a crappy situation and say 'oh no. You go first, you are poorer than me'? A sri Lankan friend of mine said to me once you would be forgiven for thinking most Sri Lankans are Catholics. Because most of them are in Australia. But he said that's because Catholics tended to be better educated and got better jobs and were generally richer. And of course better connections. If your country was about to turn to shit, what would YOU do with your money and connections? My father was a refugee. .

    In the electronics world, you just call them heat sinks
  19. danny_galaga
    This seems to be for a particular replacement reg/rec. Probably the same wiring, but also interesting since that's another source. Check out that heat sink!

    But they did all the testing they could at the time. This guy spent hardly any money on it, AND charged people to be test pilots with them. Anyway, my point still stands that Bloom was right to be wary of him, but wrong to assume anything about Rush flying an experimental plane
  21. danny_galaga
    Oh yeah? I wouldn't get in a helicopter! https://www.insider.com/titanic-sub-stockton-rush-flew-experimental-plane-visit-reluctant-passengers-2023-6?amp "Bloom said he understood that Rush had "a different risk appetite than I do. I'm a pilot, I have my helicopter pilot's license, I wouldn't get into an experimental aircraft," he said." Throwaway statement. Experimental aircraft are tested to accepted practices. This guy clearly was dodgy about his submersible and refused to test it to accepted practices but you can't surmise anything about his sub merely from the fact he flew an experimental aircraft. Wonder what he flew? Edit: he flew a Glasair 3

    I really feel it's too late in history to didn't too much time and money reinventing the wheel. Best thing is incremental improvements of reciprocal engines. The last bastion for them will be ships I reckon.

    Type 3 had a crank driven turbine instead of belt drive fan. I used to own a notchback. If you broke the fan belt you'd only end up with a flat battery.
  24. danny_galaga
    That's what made me say 'that figures' when I heard they overheat 😄 Mine is Dutch. They make lots of replacement motorcycle regulators and rectifiers. Australian supplier: vectriqparts.com.au
  25. danny_galaga
    I actually wouldn't be surprised! Funnily enough I went for an aftermarket reg/rec that costs MORE than the Rotax one 😄 . It's supposed to be more reliable, and has one less wire, the way it should be so I figured it was worth it in the long run 🙂
