    What the feeling locally in Goulburn ? Burn him at the stake or a tragic accident ?
  2. FlyBoy1960
    Please say hello to Richard for me !

    it's what 99.999999% of Australia knows as "Fraser Island" before we became politically correct

    there are lots of differences in the fuel numbers in the way they are measured around the world and many people get confused 1. RON (Research Octane Number) Mild test conditions Higher number 2. MON (Motor Octane Number) More severe test (high speed, load, temperature) Always lower than RON 3. AKI (Anti-Knock Index) — used in the USA This is the average: AKI=RON+MON2AKI = \frac{RON + MON}{2}AKI=2RON+MON That’s why US fuel numbers look lower: US 87 ≈ Australia 91 RON US 91 ≈ Australia 95–98 RON this means when you look at a number in the manual you need to make very sure whether they are talking US numbers or Australian numbers! not being able to work this out properly could mean that you are using a lower fuel grade than your engine manufacturer stipulates
  5. FlyBoy1960
    you can further the grade the engine performance slightly in this situation by turning off one ignition circuit. It's not much but it helps

    Nice Drawing.
  7. FlyBoy1960
    Maybe Amp Meter ? How much power he is pulling from the system. Just a guess.
  8. FlyBoy1960
    warm it up (the thermostat) with a hairdryer/heat gun until it's nice and toasty and then add your oil ??
  9. FlyBoy1960
    no

    I don't think you are correct with the Woodcomp props, they are manufactured in the Czech Republic and I doubt they were ever fitted to the original gazelle aircraft in the 1980's. Woodcomp are still in business, so there should be no issues in getting them but I am 100% sure they were not fitted as standard equipment to the gazelle aircraft. WOODCOMP came into existence at the end of the year 2000 as a result of the merger of the two largest producers of aircraft propellers in Czech Republic having the rich and long-term tradition.

    I know this, but it came from their FAQ section
  12. FlyBoy1960
    (turbulence) It has to be if what you are balancing is vibrating. Changing pitch alters: Blade aerodynamic center of pressure Torsional load on crankshaft Gyroscopic forces Engine firing pulse coupling Blade flex characteristics So even though the mass imbalance doesn’t change, the way forces transmit into the airframe does. and for best results you must do the balance at cruise rpm AND cruise pitch, most probably while flying ? If you balance in fine pitch but fly mostly in coarse pitch: The aircraft will still vibrate in normal flight. From the Dynavibe manual FAQ's
  13. FlyBoy1960
    you need to think about a propeller flying through the air, much like a wing on an aircraft. If you increase the angle of attack on the blades by going to course pitch you are effectively doing what you would do by pulling the stick back and getting stall buffeting in an aircraft. That is probably whether vibration is coming from. It doesn't help that you are sitting on the ground just beating the air.
  14. FlyBoy1960
    more cavitation ? loosing the laminar flow because tha AOI is to high and your losing air in the boundary layer ?
  15. FlyBoy1960
    Single blade with counter ballance.
  16. FlyBoy1960
    any guesses on type ? Looks like a Cessna (i mean really, not a journalist's Cessna)
  17. FlyBoy1960
    Facthunter, the problem is in a cooling situation the pipes contain positive pressure. In the carburettor location they are in negative pressure, i.e. vacuum, so I don't get what you are saying ?
  18. FlyBoy1960
    Show me some that have run for 2,000 hours please. Everything works well in the first 200 hours, even a Jabiru
  19. FlyBoy1960
    Thanks - I will go and do it now.
  20. FlyBoy1960
    Is there a way to BLOCK a user/person when their contributions and comments are not worthwile ?
  21. FlyBoy1960
    It's ROLL out, not ROLE out. It's FLARE, not FLAIR. 💯 (Flyboy - The grammar Nazi)
  22. FlyBoy1960
    Measured with a surveyors wheel, meant to be accurate. Seen the video and hard to tell height, but very low and didnt climb.
  23. FlyBoy1960
    The idea was the GSCC (council) would cut the trees over a 2-6 month period for training, the club would remove the stumps. Just a shame it didnt happen when the committee changed a few years back, i will bring it up again in the next meeting.
  24. FlyBoy1960
    We extended all the way to the river several years ago and gained 100 meters extra, check the Google Maps and you will see what was gained. Just a little bit more for safety. They were also going to clear the tress that they crashed into several years ago but the committee changed and it was forgotten. If they did clear then we might have had a different outcome. The Gold Coast council agreed to use the area for chainsaw instruction for their parks people and we would have got the trees removed for free, shame it didnt happen.
  25. FlyBoy1960
    800 now, there were extensions
