    Also on the Bing, you may want to check the idle throttle stop and idle jet settings. These are very simple static settings, just so many turns of a screw in each case. One of mine was out on a new Rotax, I think one idle jet, but I'm not now sure.

    Hi Lyle, if the Bing is the same as on the Rotax, the 'choke' does nothing unless the throttle is fully closed. The reason is that it's not really a choke in the conventional sense, but a separate fuel circuit that delivers through a port only when the butterfly is closed. I had thought this would be common knowledge for Rotax owners, but you can still fish up 'how to start a Rotax' stuff on Youtube, from supposedly knowledgeable operators, where they crack the throttle open then pull on the choke...

    If something went wrong with the aircraft..........let us hope not, but if.........whoever has those recordings is sitting on dynamite............(

    If there's a loud hissing too, it probably means your coffee is ready???

    Question: who has possession of the flight recorders, and who gets to extract and analyse the data? Okay, that's 2 questions.......

    This has K thermocouple temperature/voltage tables. You may be able to check at ambient with a good voltmeter: https://www.thermocoupleinfo.com/type-k-thermocouple.htm

    I don't have much experience of other aircraft, but it seems to me the Savannah, basic as it is, is very well thought out in various ways. A credit to the original designers of the Zenith 701 and those who have developed and modified it since.

    Hi Mark, I'm pretty sure that ICP made a similar adjustment to the stick pivot point. I think the problem emerged with the adjustable seats, not only can we sit further forward, but we are now sitting higher. My kit was dated Dec 2014. Here is a pic of my ICP handle, and beside it the ICP bracket that came with my kit. And the full flap position appears to have their stick vertical.

    So far as I know, not yet, Skippy. But, given his history of providing solutions and improvements..................

    I bought the excellent Kyle Communications 3 position brackets (above) and fitted this:

    Skippy, it's not so much strength as the position of the flap handle now that we have adjustable seats that some of us have set forward. The earlier Savannahs had fixed seating, fully back, so it wouldn't have been an issue. As for how much flaps: the Savannah is pretty much a STOL aircraft if you want it to be. So it depends whether you're STOLing or not...........)

    Interesting! 2030: I'll set my alarm (by the rocking chair......)

    Someone has been trying to sell a couple of these here for a while. NZ$50 or 60K each, with very much to be done......

    They're not shouldered...and it's a sh*t of a job. I cleaned the old sealant out of the thread in the head using a shotgun cleaning brush and acetone (I think that's right?) And initially I misread the manual and used the wrong sealant......so I did it twice. I don't know why Rotax don't do the same as the upper elbows, which just clamp down onto an o-ring, but I expect there's a reason...........(

    There are online models for calculating the flow. Yes, the joints seem a bit clumsy, but they are a very simple, economical and reliable way to do the join. And the 'rubber' end may serve to buffer vibration. It's not too hard to support or secure it all to avoid major vibration.

    aviatorpl I have messaged you.

    Hi PeterB, ICP who manufacture the Savannah have been supplying the metal hose with their kits since 2014, perhaps earlier. So far as I know there have been no problems with it, and I would think we would have heard if there was. As you can see in the pic, it is terminated with short lengths of 'rubber' hose. It certainly allows for a very compact installation.

    I wouldn't conflate the service style with the product. My position would be that you're wanting to buy a good product to do the job reliably: if that comes via a less polished sales outlet, yes that's pesky, but does that effect the product?
  19. IBob
    Yep, it's a nono..........but can happen......

    Curious. I asked because, thinking of the various Rotax powered aircraft at our airfield, I'm not aware of any having that failure. No doubt there will be a limit to the design output: I see 13.5A quoted. There is also a potential problem (no pun intended) with turning off the master switch with the engine still running, in which case the DC output spikes. Or that's my understanding, hence the fitting of the external capacitor, to take the edge off that. Will that damage the regulator, or is that principally to protect avionics etc?
  21. IBob
    Is it a common problem, though???
  22. IBob
    I would just go with the sheet metal: a simple job with material at hand and quickly shaped to bring the switch up to the right height.
  23. IBob
    Skippy, when you say 'extra careful grounding', presumably that includes the metal body of the regulator? I ask because I'm aware of one that appeared to fail (it hadn't) because the body wasn't well grounded.
  24. IBob
    sfG I cut a little disk to fit in the top of the tube (from one of the 6061 offcuts), with a little tab on each side going down into the tube, riveted these in place. Drilled hole for switch. It may have been raised in the centre to get the switch high enough, can't recall. Was a quick job.

    Yep, horses go nuts with parachutes overhead. As do sheep: I had my legs taken out from under me by one just as my feet touched the ground. Nothing broken but it was like being hit by a small woolly train. I also once saw a fox running in panicked circles......
