    You certainly can reduce the rpm to 5200 WOT using the prop control, however this will be a much higher power setting than the fixed propeller doing 5200. The difference will be the amount of manifold pressure which is controlled with throttle. This power chart for a lycoming shows multiple combinations of manifold pressure and rpm to get the same power and hence fuel flow. 3 fuel/power settings are shown in the chart. All piston engines behave the same way.

    Thrusters have a 4inch main tube, no doublers but it is well braced .

    I agree you can get 14 lph but don't call it 75% power. The rotax charts that Blue posted show the fuel consumption at 75% which rotax say is only 68hp, weird maths if you ask me but anyway that is 18.5lph. The altitude chart is very informative.

    Skippy you need to use a calculator. 75% of the 100% fuel flow will be 0.75x27 lph = 20.25. L 5000rpm will only be 75% power if the propeller loads the engine to 75% and this will only be correct for one altitude. 5000rpm at 2500 feet is much more power than 5000rpm at 7500 feet. Performance charts for any aircraft will only be correct if the factory propeller is fitted. If the propeller is ground adjustable all bets are off.

    Mike, I believe the aircraft above was bought by a guy in central West NSW. Was an un flown prototype?
  6. Thruster88
    You could drill a hole into which the plastic over flow tube would fit tightly. Can cut the tube at an angle so it can be pulled through then cut off. Some slack in the tube will allow the cap to be removed.

    Cross out "are trying to produce" and replace it with HAVE PRODUCED. Impediments to this, Lawyers, vested interests, useless government.

    Interesting to see the exhaust early in the vid. Looked stock Rotax, no dual expansion chambers. The exhaust was wrapped maybe to minimise cooling drag and maximise exhaust thrust, every bit helps. The 582 tuned up could produce 100hp given it's displacement.

    Would be nice if we could have something like this. Never happen in Australia. LA Special Flight Rules WWW.AOPA.ORG Want to fly over one of the world’s busiest airports without talking to ATC?

    This happened on the apron at cowra on a low wind day a few years ago. Pilots left the aircraft for a short time. Empty weight about 430kg for the piper colt.

    I guess the real question is if everything went to plan and the two aircraft missed by 100 feet would this be acceptable. No is the answer.

    Will you use ripper, the Gallion stallion in your gold prospecting after building the runway? I believe metal detection people use them to strip off the surface layer.
  13. Thruster88
    Interesting they had left and right handed heads. Most aero engines have only one type of cylinder.

    Bolly test their propellers with a V8 engine and spin them to well in excess of there design speed. I like by 2 blade bolly on the 582 rotax.

    JR rudys point 2 about ATC not providing the helicopter with traffic information is just plain wrong. Listen to the tape. Paraphrasing "Traffic is a rj700 at the bridge for runway 33" at the time of this transmission the helicopter was about same distance from the pinch point as the jet, both aircraft similar speed, what to do what to do, slow down maybe so the jet passes ahead?
  16. Thruster88
    We now know the helicopter was flying the 200ft or below route along the river. Looking at the chart, the passenger jet has to cross the helicopter route while descending, about 3/4 mile from the threshold of 33. 3/4 mile would put the jet at about 200ft yes? An accident waiting to happen.
  17. Thruster88
    Looking at the replay on fr24, runway 01 mostly and 33 occasionally were in use, this would have been on the Airport Terminal Information Service. The helicopter pilots having sighted the jet may have believed it was on approach to 01 thus placing it further away than it actually was on the 33 approach. Distance can be hard to judge at night.

    Is the security check a one off for a part 61 license holder or is there an on going requirement to hold either an asic or avid?
  19. Thruster88
    My guess is there would be a fair percentage of pilots of both types that have neither an asic or avid.
  20. Thruster88
    Why would the helicopter not cross over directly above the runway?, to be flying in the known approach path of large passenger jets seems stupid.

    What is the red ultralight hanging up
  22. Thruster88
    After watching blancolirios vid it could only be described as a cluster f on so many levels.
  23. Thruster88
    Farm, motorbike, our best engineer.
  24. Thruster88
    Airtractor 802 fire boss is a very impressive aircraft.
  25. Thruster88
    RFguy admiring the ? and a 1985 ultralight still being flown and enjoyed in 2025.
