    Dear Oh Dear , Mr Turbo planner. what were you thinking when you wrote that?......... I was a little bit on your side for a while there, well, sympathetic to your situation anyway....... Here comes Mr. Completeaero geek, trampling all over your beliefs and theories, Then you go and drop a howler as bad as ever I've seen. Quote" That's what he said, and a sprint car wing is curved on the bottom and flat on the top, so the resulting force is down, not up." What Resulting force? Set the cord centre line level with the ground, where's your lift now? Did you ever take a look at the angle those "wings" are held at? It's like, 30 degrees! It's the ANGLE OF ATTACK that gives them the (Down)thrust. I wouldn't mind betting that the downforce would be almost the same were the "wing" a flat plate. Just a whole lot draggier......Please continue the debate, But don't post in anger....it's not helping you....Cheers, and good luck....

    Check with FGI on Centre road, Clayton.... I think I bought some there a while ago ( I thinned epoxy with it I believe) .......

    For my part (however small) I think that it is critical that pilots know how a wing works, how lift is "generated" (actually, it's not generated as such, is it? but is a by-product of AOA )...I learned to fly very late in life, but had an enormous advantage in having flown contest FAI glider (and some power) for 30 years...I already knew what happened. I believe if people KNEW what was happening as they were flying along or in a circuit then the incidence of stall/ spin accidents would be considerably lessened. ......

    Dr Mr Completeaerogee, Please don't stop posting, I'm certain there are other principals that you can shoot down. I have been vindicated in what I have thought for many years....This all both entertaining and instructive, no matter what detractors say....By the way , Do you know Richard Dawkins, from your posts you may well be family?

    thanks for the posts Completeaeroge, very informative and educational.....

    the Mornington Peninsular is 2 hrs from Albury. Try Tyabb or Tooraddin( Great Restaurant) or Lilydale which is not so far . Although I see that it depends how fast you fly! Less Far? Benalla or Mangalore.....

    I was having some Bundy tubing bent for fitting a new fuel line forward of the firewall. The existing one was copper, which, apparently, is a no-no. NZ hoses made such a balls up of the job I bought more tubing (NZ Hoses didn't try to charge me , Thank you!) and made my own tube bender. I rolled the tubing in a 3" dia circle without crushing or kinking it. Should anybody feel the need to bend 3/8" tubing, you can borrow it for the price of the postage....................Plus I also made the 37 degree flare tool

    ? creeped you out or crept you out?

    Airquip used to sell it, now a wholesaler in Oakleigh (Melbourne) sells it. I paid $170 for a length of 2 1/4" that was 10ft I believe. I can look up the receipt if you like. I tried NZ hoses but they wanted $ 344 for 10ft......I'd try Skyshop first....

    sorry , not illegal, just ill advised, My POH says 12 knots @ 90 degrees. I have landed at that, but it was very exciting!
  11. geoffreywh
    a 15 knot crosswind would be beyond many taildraggers recommended (POH) crosswind max. Thus illegal!....If I were confronted with a crosswind like that I may well go somewhere else!
  12. geoffreywh
    where do you live? I'm sure there is a ( retired ?) fitter/turner/machinist that will throw an hour or two your way?

    I have left (this year ) mogas in my tank for 16 weeks with no ill effects. ( BUT not in the carb!) If you care to check, Japanese motorcycle fuel lines are ok at 20 years plus. No hardening , no cracking. It's available from wholesalers. BUT it's black.......

    Jabiru USA video

    geoffreywh replied to jetjr's topic in Jabiru

    last time I looked the pistons were cast. being holden parts. forged pistons would go a long way to reducing piston problems! neither have I ever seen forged piston pins! machined from drawn round at best...

    That's probably what I would do!!! There's a video of a turbo Viking on you tube in a Ch701 seems to be operating fine....I know he made a complete cock-up of the Subaru conversion and did bad things financially. But I would still do a Viking conversion if I could. $US 13800 ( plus gst/freight ) is just unbeatable

    some people are not getting the intended irony in my post. I said that the 230 MUST have had at least 15 ltrs left (otherwise he would have been operating illegally) -- You should have 45 minutes reserve in the tank when you land...... For all I know he had none, very little or lots, probably NOT exactly 15 litres!!!
  18. geoffreywh
    Bugger. The solid state sensor does not work with earlier gauges. and 10 x 1 thread , so remove oil pump housing tap hole to 10 x 1 and refit. Now I have to find a correct gauge... A modern stepper motor type I'll be bound.......Also expensive... Why O why can't I fit a mechanical gauge. Job finished in 20 minutes. $fifty bucks..... At this rate the job will cost more than a $1000 (really, no kidding!)
  19. geoffreywh
    Scary! at least 15 litres+ left ( 45 minute reserve ) and not knowing you are not gonna be able to use it. I'm so glad it wasn't me Well done the PIC.................right?
  20. geoffreywh
    How about fitting a known mechanical gauge and testing? That should do it.......................................... The new sender( sensor, engine mounted) appears to be a Honeywell product and is very expensive. It has a 10 x 1 thread , so will require surgery to fit earlier models...If it stops the problem then OK.....
  21. geoffreywh
    Er ??? Anyway, I visited Bert Flood's and they have an alternate type for the 912

    Sorry it's a 24 reg certified aeroplane. I can't move anything without manufacturers permission and they're not talking....................

    Servicing a Rotax engine, noticing low oil pressure...Seems I need to fit another oil pressure sensor. That's got to be the third one in a year or so. Does anybody know of a better version? The damn VDO ones are just so prone to failure...Even on their website they say "Not suitable for aircraft engines. Due to pulsing oil pressure which leads to contacts wearing out " ....Surely someone makes a better mousetrap....(and don't call me shirley)
  24. geoffreywh
    How does that work? I thought that there was only the fuel switch on the centre console......Don't both tanks feed the header with no switches....
  25. geoffreywh
    i reckon it's the same one
