    Liquid cooled heads

    in Jabiru

    Posted

    I have removed the LCHeads from my Jab done a 2.5 hour flight temps where around 190 - 205 F on cruise I am happy with that.

    You are kidding right? 205F = 96 C. Mine don't go below 145C in cruise.......

     

     

    Mobiles.....

    Several men are in the locker room of a golf club when a mobile phone on a bench rings. A man engages the hands-free speaker function and begins to talk. Of course, everyone else in the room listens in.

     

    Man: "Hello."

     

    Woman: "Honey, it's me. Are you at the club?"

     

    Man: "Yes."

     

    Woman: "I'm at the mall and found this beautiful leather coat. It's only $1,000. Is it OK if I buy it?

     

    Man: "Sure, go ahead if you really like it."

     

    Woman: "I also stopped by the Mercedes dealership and saw the new 2015 models. I saw one I really liked."

     

    Man; "How much?"

     

    Woman: "$98,000."

     

    Man: "OK, but for that price make sure it comes with all options."

     

    Woman: "Great, I love you honey! Oh, and one more thing, the house I wanted last year is back on the market. They're only asking $950,000."

     

    Man: "Well, then go ahead and make an offer of $900,000. They will probably take it. If not, go the extra 50 thousand if you think it's really a good price."

     

    Woman: "OK, I will. I'll see you later! I love you so much! You're so generous!"

     

    Man: "You're worth every cent, darling. Bye!"

     

    The man hangs up. The other men in the locker room are staring at him in astonishment, with jaws hanging.

     

    The wonderful husband turns and laughs as he asks: "Anybody know whose phone this is?"

    TL Carbon Sting S3 Pros and Cons

    in AUS/NZ General Discussion

    Posted

    Be very wary of carbon fibre in any aircraft. In the event of a crash-fire carbon gives of noxious fumes and must be disposed of in a regulated manner (as asbestos does). An RV-6 had carbon parts fitted, crashed at Gatton and fire crews had to dispose of carbon parts. Could very well push up insurance or leave you with a large bill......

    Raizo, call things what you like: you made it:yes:

     

    Welcome to a very select club. Lots of people start building a plane but never finish. Life, or the magnitude of the job hits home and they give up.

     

    Congratulations, enjoy the flying and the years ahead.

    Retirement......

    in Aviation Laughter

    Posted

    After 35 years, mailman George decided to retire. On his last day, he makes his usual rounds.

     

    When he arrives at the first house, the whole family comes out, congratulates him, and sends him on his way with a tidy gift envelope.

     

    At the second house, they present him with a box of fine cigars. The folks at the third house hand him a selection of terrific fishing lures.

     

    At the next house, he is met at the door by a strikingly beautiful woman in a revealing negligee. She takes him by the hand and leads him up to the bedroom, where she blows his mind with the most passionate sex he has ever experienced.

     

    When done, they go downstairs, where she fixes him a giant breakfast. As she pours him a cup of coffee, he notices a dollar bill sticking out from under the cup's bottom edge.

     

    "All this is just too wonderful for words," he says, "but what's the dollar for?"

     

    "Well," she says, "last night, I told my husband that today would be your last day and that I wanted to do something special for you. I asked him what to give you. He said, 'Screw him. Give him a dollar.' But breakfast was my idea."

    Jabiru engine cooling

    in Jabiru

    Posted

    I found I had to disconnect naca duct on cowl to mixer box. With extra pressure the engine would run very rough at full revs. Runs fine now. Put a filter on naca to slow flow into cowl, but still plenty of fresh air to mixer box. Carb inlet temps also higher. Egt's much more even as a result. Full power climbs and middle cyls always run coolest egt.

    That fuel flow looks a tad low for a 3300 @ 2800 RPM.

    I read conflicting reports on recommended head temps for cruise....Jabiru don't publish a range to aim for, rather just a max to avoid.

     

    Limbach recommend cruising at between 150-170c , but to keep below 200c at all times, as per http://byrongliding.com/wp-content/themes/common/docs/Limbach_Tech_Bulletin_44.1.pdf

     

    That fuel flow is with standard jab bing and drops down to 17lph at 2750 rpm, goes up markedly above 2850. I presume the tapered needle is doing its job....

    [ATTACH]33111[/ATTACH] [ATTACH]33112[/ATTACH]This works a treat, I can maintain full power indefinitely, Max's to mid green, cruise sets at the bottom green. I've got the numbers somewhere.

    Full power, 250f = 121c

     

    Cruise........205f = 96c

     

    That's reading from LHR cyl head ( cyl 4 ...I think )

     

    Your figure 150......f.....or Celsius ?

    Celsius. Just how deep is that lip? Mine is 50mm but that looks to be more.
