    As to experience counting, I took a mate of mine up in a Tiger Moth at Broadmeadows (District Park) Newcastle and he was a very accomplished Model plane Builder and flyer and I reckon I could have soloed him in about ONE hour..Nev

    The state Police in the location of the crash have the authority to investigate and always have. AUF or RAAus have never had such authority. ATSB can elect to but have limited funding so only get involved in the ones they give priority to. ATSB and the Police are INDEPENDANT. The CASA and RAAus aren't as they are major Participants in the "Game". THAT Report misrepresents the situation. Nev

    The position of the diaphragm is controlled by the throttle position AND the engines ability to pump air.( LESS at high altitudes) IF you load the engine and thereby reduce the revs it will be very limited in the POWER it can produce. Look at any Torque, RPM and HP chart produced on a dynamometer. There will be a MAX torque RPM and well above it a max SHP RPM as well as a never exceed RPM. Nev

    IF the system includes a governor It will maintain a SET RPM regardless of the Airspeed of the aircraft. The pitch will adjust to keep the RPM constant.. In a dive as the speed increases the pitch will become coarser. In a climb as the speed reduces the pitch will fine off. In Flight adjustable is when you decide what the pitch will be.. Nev

    PSSst He hasn't lifted the Lid. Nev

    Be OK when you get the Hang of it. Single Pisstin and flies? Nev

    I think HE posted here a few times. RAAus doesn't Investigate RAAus planes. The relevant STATE police do. Nev

    You sure Ain't going anywhere without a TAIL ROTOR.. Nev
  9. facthunter
    Drive and control mechanisms for tail rotors are complex. Nev
  10. facthunter
    That's probably AFTER it contacted something. Nev
  11. facthunter
    Move to Cowra? Nev
  12. facthunter
    They never DIE gracefully.. That could have had something amiss with the tail rotor. We always assume the pilot mucked up.. Nev

    I'm only talking about Saphire's. I have NO knowledge of the Streak shadows etc. Nev

    A stepladder with a cushion on it would be more appropriate.. Nev

    Read it on one of the expanded sites. Nev

    I think he was seriously injured. Lucky it wasn't worse.. Nev

    The performance chart above has all the information you need to know about the effect of varying RPMs. Nev

    Very clean and efficient and a bit elevator sensitive. Everyone I knew has passed on. Fan cooled 447 Rotax. 2 different versions of the plane as I recall. Worth having one in my opinion. Nev

    Same in-principle issue with anything other than a jet. Even then cruise climb is a faster way to get there.( where you are going) Sometimes there is a definite "inversion Layer" which rises until mid afternoon where it is smoother above. Often around 10-12,000 ft. in central Australia. Nev

    I don't think they were ever strengthened but that doesn't stop it from being a good idea. Like a strutless wing the most bending stress in near the root.. Nev

    The dashpot is only elevated by the pressure difference across it. As atmospheric pressure drops the difference does also. This is how the taper of the needle adjusts the carburettor for altitude mixture. (stops it being too rich). The fuel is always sucked out of the needle jet. It's NOT an injector. Nev
  22. facthunter
    With no prop at all you'll get destructive revs with about 1/8th throttle. Like running a car in neutral. . A CV carb is different to all others and there's always some pressure drop across it. At higher altitudes the dashpot doesn't fully open. At lower revs your engine doesn't Pump as much air. so won't make as much Horsepower.. I also understand Rotax's don't like over propping. . Nev
  23. facthunter
    That's an absolute necessity. Nev

    A fast plane gives you a rough ride on a hot thermally day. Nev

    Some forecast winds are such that you just don't go. Nev
