    Oh nooo!!! Now the internet has provided two different answers to the question! But someone on our forum has gone to great lengths to assure me that the internet is a great source of fast, accurate research! Maybe I'm better off going back to sitting around the campfire debating our own theories, and drinking (good) wine. The old way was good enough to arrive at the same possibilities as the internet experts did.

    So, Marty. You're implying that the advent of the internet would have led to a responsible reduction in my alcohol intake, but also hampered my ability to respond to a debate. If that happened, I would have had to wait until I got married to learn the art of debate. Bah, I think it was more fun without Google. Sitting around a campfire comparing Google searches just isn't very challenging. BTW, thanks for the answer.

    Quote/"Does a fly do a half loop or a half roll to land on the ceiling? " When I was a young impressionable bloke, that very question caused a group of us to spend an entire long weekend consuming excessive amounts of alcoholic voice lubricants, in order to solve this important aviation conundrum. We never did come up with the answer.

    In Ross's case, I believe the post crash fire had prevented a meaningful investigation into the cause of power loss.. We will never know what the cause was.

    If, as was suggested at the time, there was initially a partial loss of owner before the engine failed, it may have caused Maj to hesitate before taking action. That would explain a loss of airspeed before he attempted any manoeuvre. I had a GA912 Lightwing . I once took off with both fuel taps turned off. I till can't believe my mistake. I am not suggesting for a moment that Maj did this. However, my experience is that my aircraft had sufficient fuel to climb on full noise to a height of about 200 ' before faltering, spooling down, then shortly after that going quiet. In my case, I put the nose down instantly and maintained flying speed until landing in the crop off the end of the strip. I did have that option. To lose our good friend after similar circumstances shook my confidence totally. I haven't got over it. I didn't really know Ross well but I felt closely connected to him. When I sold my a/C it had dashboard labels that he gave me. Ross, you are greatly missed by all of us, not just your immediate loved ones, but also your extended aviating family.

    OME, what activity would you like to see? If you like I'll post something contentious, to get the ball rolling. Maybe Ian could have renamed it "Let's start an argument"

    It'd be nice to see somebody challenge the coppers. They sometimes seem to put themselves above the law.

    Some Aborigines are drone commanders. I've heard!

    Do police drones have wings?

    When Boeing say "Trust me!" No wonder QANTAS engineers are a bit skeptical. And no wonder QANTAS (to their credit) started inspections early!

    Merkans don't speak English, old mate.

    Does anyone remember Col Paye? It seems he ran a crop duster back in the sixties. This pic was titled 'Col Paye loading his crop duster.'

    Do you mean to say that you are down under downunder.........?

    The complaints sound just like the noise we used to hear, years ago, about 'those mad clowns who fly ultralights'. Out in the boonies, no danger to the public, taking a calculated personal risk, under 300' altitude. Probably safer than early ultralights because test flights were undoubtedly undertaken without a person attached.

    In the January fires we watched a N.S.W fire 737 make two runs, water bombing just west of our home. The fire had crowned and the police had visited us to ask us to evacuate. There was a small twin turboprop spotter plane circling above, a Hercules, a couple of helicopters, and the 737. A busy time indeed. The 737 came in low, maybe 500', slow, and all flaps clearly hanging out. Hardly any noise (not that it would have bothered anyone). It disappeared over the trees before the drop so we didn't see that. All in all, quite a sight. Our personal airshow.

    There is one little trap to watch out for with polycarbonate, as I discovered after replacing my aircraft windscreen. When the Lightwing factory built the aircraft, they sprayed about an inch wide strip of white paint around the perimeter of the screen, on the inside. It does look neat. So I copied this, only to find that spray paint can cause shallow crazing of the plastic. This showed up after I fitted the screen. I don't think it is affecting the structural quality of the plastic, as there have been no actual cracks anywhere. Just that annoying slight sparkle in a couple of places.

    Be Careful. Lightwings can be addictive!

    There's nothing wrong with "crappy" permanent magnet alternators. Unfortunately at this stage there seems to be nobody making a good regulator for them.

    Just to add my limited experience here: My Rotax 912 powered aircraft was equipped with a fuel pressure gauge and I noted that the Facet pump only raised the fuel delivery pressure by one psi. The pressure remained well below the Rotax recommended Max pressure. So far, so good. However my fuel flow gauge showed a significant increase in fuel flow when the Facet pump was on. This remained unchanged after replacement of the float valves. I mention this for the benefit of pilots who may desire to run the Facet boost pump continuously, without pressure and flow monitoring. The increased fuel consumption could cause flight planning problems when the tanks go dry a bit early.

    Cherk, If you happen to be on that 'other forum', Please let Bex know that he has a whole bunch of mates over here, wishing him well, and eagerly waiting to heap shyt on him whenever he's ready. Oh, and there is also a whole bunch of us who are also members of the 'zipper club'. We know how it is. And many of us have been through the hoops in the process, too.

    Way back when I worked for Telecom Aust, they had that motto. As they madly "resource rebalanced". (That means getting rid of as much of that greatest asset as they can)
  23. nomadpete
    I am worried. Until now, nothing has successfully silenced our mate like this has.

    The "crowbar" is simply like a switch in between the alternator supply and the battery. (There are two types of scr regulator, the most common is series type) When the regulator senses 14.2volts at the battery, it open circuits the path. In that way, it functions as a simple "overvoltage cutout". When this happens, your electrics are expected to run off the battery. The big electrolytic capacitor (as recommended by Rotax, not sure if Jab have), is important to smooth out the spikes that the regulator produces as it transitions from "switch closed" (direct connection between alternator and battery), and "switch open", (fully charged). That phase is characterised by continuous short spikes of full charge voltage. None of these circuits I have seen are capable of providing any charge unless the battery voltage falls below a threshold. Usually internally fixed at about 14.2 volts.

    Having said all the above, I feel that you have a wiring problem, rather than a regulator one. After all, the regulator shouldn't cause total loss of electrics.
