    I suppose that depends on how we want to interpret the statistics. I would think not as you have averted failure. I had a C-150 tail dragger for several years and the 0200 often had what appeared to be 'soft' compression (hiss in exhaust on pull through) when cold and having sat for a while. I reckon pulling them through cold after sitting for a while is not an accurate way off assessing things as I'm sure if the exhaust valve is open for a while (parked) then exhaust byproducts/carbon etc can find it's way onto the seat showing up as poor compression on pull through. Give the engine a run briefly, stop it and try the pull through again, compression back and no hisses. No doubt it the hiss remains then it's time to look further. The LAME's often talk about doing the 'Indian rope trick' lapping in the valve to fix this issue. With the Jabi it's not necessary to to the rope trick as the heads are simple to remove and do the lap job properly.

    Unfortunately Alf we don't see much of you in our area! Sandra Lewis' and Nelson Smith's made it to over 1000 hours with routine servicing. I'm pretty sure Anthony Morrison had a good run with several in his school. My serial number 049 did between 500 and 600 hours without failure.

    I just sloshed my Jabbie UL450 fuel tank with Kreem which is supposed to make it compatible with mogas and even ethanol laced mogas should it ever find its way into the tank. Bought it from a motorbike shop. Not cheap at about $60 for a quart. It stinks to high heaven but seems to stick like you know what to a blanket.

    It's interesting that 65 knots is being used for the approach speed. I would have thought that you would be aiming for 1.3 times stall speed for any given configuration. Therefore with a full flap stall speed of 40 knots the approach speed should be stabilised on 50 knots. This buffer should be enough to provide the required energy for the round out/ flare and then there will be minimal float before landing.

    The Coroner's finding will be available to the public - the Inquest Brief may even be available after the Coroner makes a finding through FOI.

    And your point?

    I wonder if the use of a Spot Tracker would assist the searchers? I and many others use one for paragliding and we are able to monitor each others location in real time. They aren't that expensive to own or operate. It will certainly be an essential piece of equipment in my Jab UL 450 when I start travelling around. Regards, Laurie. http://highcloud.net/spot/ just click on the word SPOT on the line of any name and you'll see what I'm getting at.

    The 12 sided nuts you are looking at is the initial AD where the original reduced head nuts were replaced with these. Even though there is no lounger the required 1.5 threads showing through the grip length of these new nuts is greater than the original - by about 1.5 threads. The second part of the AD to be completed at top overhaul time was to replace the through bolts and studs with new longer ones that allowed the correct 1.5 threads to protrude. Unfortunately there is more to the problem than nuts or bolts/ studs - the source of the problem relates possibly to hydraulic lifters. It would be interesting to hear from someone who has converted their late model hydraulic lifter engine back to solids as to whether there have been subsequent through bolt issues....

    Huh?

    Well said Daryl. Good to see you popping up on this forum!

    MOTOW, I've got one and it works great :) http://www.ebay.com.au/itm/MO-TOW-MOTORBIKE-CARRIER-TRAILER-REPLACEMENT-MOTOW-/170946307199?pt=AU_Motorcycle_Parts_Accessories&hash=item27cd31a47f&_uhb=1

    Have you considered 'free flying' as in unpowered paragliding or hang gliding? You have some beautiful coastal flying sites in the Sydney region plus if you feel the need to be challenged a bit more, go inland. I started paragliding about 3.5 years ago and have almost 300 hours, including over 100 inland. Inland flying at over 8000', in excess of 6 hours and 100 km. It's a fantastic sport/hobby. Great fellowship too.

    Same here. Great service. I renewed my pilots certificate on line and bought an aircraft log book - they arrived within days. I also spoke to someone in the office about registering my project, a Jabiru UL450, and received a complete package very quickly along with helpful advice on the phone. Makes me wonder whose side the ex RAAus executive members now employed by the government are on. Or whether they actually do have the betterment of our organisation at heart.

    The cowl ducts are not 'half blocked off' - the idea is to direct air to the upper side of the cylinders and around them from above. This wont have much affect on oil temperature. You will need to block the air flow to the oil cooler - usually situated on the font face of the sump with its own air duct.

    Interesting maths. 200 hours at $450 per hour is $90,000. Are you sure about this statement?

    Thanks Mardy. It's just that I'm finishing off an 'old' Jabiru project too - a couple of years younger than yours I think. Looking forward to getting it going. Yours is looking very nice. Did you do the paint prep and painting yourself? Laurie

    Looks like a good bit of gear and reasonably priced. Pretty weighty aren't they at over half a kg.
  18. Keenaviator
    Thought I'd get a bite.

    Probably not so we'll need both. Maybe an old 121.5 epirb will cover the legal requirement. Maybe some of the forum's bush lawyers will add their two bob on this subject.
  20. Keenaviator
    I've gone for the SPOT 2 even though it may not be regarded an epirb/ plb. With this unit you can have many responsible people monitoring your SAR.
  21. Keenaviator
    What's the engine number Mardy?
  22. Keenaviator
    Thanks for posting the results Mardy.

    Sounds like experienced a low level inversion. The air within the first few hundred feet of the ground cools overnight but the air above is still hot. The wind you found above this is the 'real wind' and it will get to ground level as the ground warms up again matching the air temp above this inversion. This is very noticeable in trikes on summer mornings. Laurie.
  24. Keenaviator
    Trim works fine on those I've flown.

    Or even better as a retrieve vehicle from a 200 k flight! This is one of the reasons I let my Corby Starlet go and now building a Jabbie - the Starlet had no room for my paraglider and there are airstrips at so many good paragliding locations. Laurie.
