    Yep, I found the stick very imprecise. I can't remember the exact number, but on the Sav with a blade horizontal, each degree of pitch is about 20mm on the floor, so you really can set up very accurately....though you do also have to check tracking (any difference in how far forward/back each blade tip is), as that can throw this method out. I'm pretty comfortable with the way I do it; however I'm sure there are inclinometers now available that would do just as good a job.

    Very nice, Marty: I've certainly been very happy with mine. I made a simple but effective laser pointer that hooks on a blade and projects onto the floor, used that to pitch all blades identical, have enjoyed super smooth running from day one.

    I believe they were used for navigation training out of Booker airfield near High Wycombe in the UK where I grew up. We saw (and heard) them overhead pretty much daily in the '50s.

    Seems I'm more than a little out of touch......there is a whole load of this stuff, done by the same people.

    All good. You'll also need something to strip the wire neatly and precisely: for the D sub pins, you're only taking about 4mm off. If you can find a well made version of this type, they are ideal: https://www.trademe.co.nz/a/marketplace/building-renovation/tools/hand-tools/pliers/listing/3524919310?bof=UX48xEQA I have the cheap knockoff version, and while I was able to adjust them to do the one job correctly, I wouldn't recommend them.

Does the job just fine. The 26-20 is the range of wire gauges. Part of the reason for the high price of the industry ones is that they have fittings for, and can be adjusted to work with a much wider range of wire sizes (and pins?) But you don't need that flexibilty: D-sub is one size and length of pin that accepts a small range of wire sizes.

    I've had nearly similar but could have been worse. And there is that pattern again: a set routine that is normally reliable........... is disrupted in some way part way through..........and so not reliably completed. What I have tried to take away from my own experience is this: if my routine is disrupted, go back and start over.

    Savannah POH calls for: 11.5 - 14.5psi for 6" and Tundra tyres. 29 - 36psi for 4' tyres.

    Looking again at that landing: The wishbone and wheel are hanging straight down under the aircraft, so on landing one of 3 things can happen with it: It remains vertical and digs in in some way, perhaps tearing off. It tracks left and folds under the aircraft. It tracks right, where it is out of harm's way. It looks very much as though the pilot deliberately sideslipped left all the way in, which would deflect the wheel to the right, out of harm's way.
  14. IBob
    Correction: Still don't know. But the way the damaged u/c tracks after he lands suggests that the wishbone and wheel assembly are intact?
  15. IBob
    Don't know yet. The wishbone with attached wheel was still there, something on the olio or spring assembly under the fuselage has parted company, allowing the wishbone and wheel to hang down unrestrained.

    Hey guys, enough of the unsolicited grammar lessons! I had no difficulty understanding what Tozza has posted, and surely it's the exercise here that matters? If you don't like his pitch, you're not obliged to engage.
  18. IBob
    Hi Tozza, just did your survey. I note there us no option for New Zealand (so I identified as Australia). There are a few Kiwis here, you may want to look into that? All the best with your survey. Bob

    But....apologies to F10 for the thread drift............(

    OK, I was born there.....we're fine people....just misunderstood.........) I can also tell you a difference between visiting Glasgow and Edinburgh people: The Glaswegians will say 'you'll have some tea', while the Edinburgh folk will say 'you'll have had your tea'.........)

    So. I'm not familiar with the internals of those engines: was the problem that someone did some disassembly and someone else did the assembly and missed something that had been disassembled?

    IBob commented on red750's aircraft in Unique Aircraft

    I saw a Trimotor at Strathallen in Scotland in the late '70s. We couldn't believe how slow the approach was, it seemed to take forever to come over the fence. Someone had found it in Spain, and it was on it's way to a collector in the Sates, flying 'over the top' which was probably the safest route. We tried to get a jump from the thing, but the ferry crew were understandably not interested. We later heard that it had struck head winds on the next leg and turned back, having burned a significant portion of available fuel without actually clearing the coast. No news after that, so no doubt they made it....eventually.

    Some nice low level footage.........followed by diligent effort to destroy the evidence.......... Note also second kea: these wee bastids often work in pairs or groups, with one or more providing a diversion while the crime unfolds behind you........

    Just removed old Becker (German) Xponder. Screws for that are 3mm.
