    Thruster 88 I suggested something like that what now seems ages ago. A design has to be practical or it's a gadget or contraption. Form follows Function. Nev

    You haven't listened to a word I've said. "Bow" anyhow. Nev

    Have either of you two ever operated planes with cowl gills? Nev

    Rubbish Geoff. My view is fully backed up by my explanations based on a lot of experience. Discipline is a vital part of aircraft design more than most other and I put safety at the top of the list and will continue to do so. I'm, NOT against cowl flaps and have pushed them for YEARS. Simplicity IS safety. I'm very open to GOOD practical ideas. Overcomplicating this actuation is certainly NOT one of them. ALSO you are not the only person with University engineering and materials and structural technology training. F me this shouldn't need to be said. "Fiddling" with things aeronautical is risky. Nev

    Entirely different aspect to the CASA request. Nev

    Cowl control is before the event as well as reactive to a condition. ie shock cooling on a Power off descent of significant duration Like after para drop or when an engine has been feathered. Gills to "Trail" in the circuit where you are busy and open on the ground after landing. Nev

    Now we are going Automatic.? .Totally unnecessary. A wax stat has very little actuating power and moves about 5/16 th of an inch. That Fiat is also fan cooled and operates under widely varying loads in a totally different environment to an aero engine, on the ground, where IF it fails you just stop and fix it. Nev

    They are looking for "More" video or information. NOT our opinion of what caused it, based on what is already available.. It SHOULD have had plenty of power.. Nev

    It looks like being too slow and getting above ground effect. There could have been windshear or a gust/ wind change. That's all it takes. Nev

    The answer/solution is worse than the original problem. Manual actuation gives you "Feel" so the linkage doesn't get destroyed by something getting misaligned etc. The controls on a DC-9 are manual by servo tabs. Ona DC 4 they are just manual Max wt 72,000 Lbs. You are talking about a single cowl flap on a very LIGHT plane. Introducing risks where none needs to be. Weight Costs Complexity and unreliability. BAD design and design philosophy. Nev

    We're flogging a dead horse here. Fairly large flaps are operated Manually and if you have a cowl flap (which is a good idea from engine management and drag advantages) why not make it adjustable in flight over the whole range? Nev

    Don't forget ANYONE can read this forum. Have a look sometime and see how many "guests" there are. Some of your Copy would make good fuel for the alarmist fire. Nev

    LAZY irresponsible reporting. No excuses really. ABC. Nev
  14. facthunter
    Get the REAL thing. Many were totally rebuilt at Luskintyre near West Maitland. They have a steel tube fuselage and many have brakes and radio. Aerobatic as well. Nev

    "Advanced" at the time. Near universal NOW.. The "Context" counts. Nev
  16. facthunter
    YOUR LOGIC is centred around cost. You are the one doing doing the cherry picking.. Nev

    The rocket is i in the "Dangerous goods" category. Nev
  18. facthunter
    I assumed it was only ambient air. If you're leaking oil, the engine may runaway. Not turn off. Nev

    Bugger Me Why START another thread on EXACTLY the same article as a recent existing one? Nev
  20. facthunter
    The smoother inner surface will flow better. Nev

    Can't hold the NEW GA back. Onward to the Moon and the Stars. Get with it ,or out. Nev

    The SAAA does a lot for the active builders, justifying the high? fees. but the discount to those not needing of that service is a Piddling amount so they are subsiding the others. That and leadership instability is the reason I left but that's a long time ago now. This one "sat' when I fed the dogs but here it is a bit late Spacey's Hummel bird gets a lot of action even if it doesn't fly..Nev
  23. facthunter
    Realistically, I don't think it will get a lot of support from the Current RAAus. but I wouldn't mind being proven wrong on that. We used to fly things like the quicksilver MX. and Winton grasshoppers. Nev
  24. facthunter
    Why "think" about IT then? Neither of those you mentioned would fit a Part 103. I say IF the USA can have it why not US eh!. Nev

    You're supposed to be able when VFR to navigate by features on a map WAC and derive tracks and calculate headings on the wind forecast and I also used goggle earth Prints of the destination and surrounds. You calculate track LSA's from Info on the WAC and get a good idea of the terrain and where high hills, powerlines and rivers etc are. Proper Planning Prevents Piss Poor Performance. You also get an idea where suitable alternates are and lower country if the cloud base lowers. Nev
