  1. And they'r still for sale in Sydney for $30, supposedly for children.

    All unlicensed and under age for the law to do much other than confiscate kids toys.

     

    I have a need for an illegal "catapult". to get a rope-line over my tree branch, prior to pruning.

    I wouldn’t worry too much about them. I got one as a present and there is a built in altitude limiter of about 40 feet.

     

     

  2. I wonder about the efficiency... P=IV and at say 100 amps and 40,000 volts thats 4 million Watts.

    Here is a failing of my brainpower though...  how does the thrust actually get applied to the airframe?

     

    I know it does, but just how and where?   But overall, wow!

    This still has a lot of Bernouli in it.

     

    I've read elsewhere about the effect forgot where, and there was more emphasis on the positive vs negative for use as thrust.

     

     

  3. Funny how some people have never been able to make the transition from car to aircraft.

     

    One concept which has come close to fruition was shown in Popular  Mechanics in the late 1950s

     

    It looked like a late ‘50s convertible with a ducted fan through the bonnet and another one through the boot. Add two fans for stability and you’d have today’s drone layout.

  4. What's even worse, OME, is that if even one of these current scandals had been associated with a Labor government, the media would have hounded them out of office.

    Methinks a very different standard of behaviour is applied to those who were born to govern.

    I think the media have protected several members of your party, the most famous being Bob Hawke who was described, in Parliament, by another member as a "Boudoir Bandicoot". The press reported it but there was a shrug from the community. Given that members of Parliament are elected from their peers, that was not such a surprising result.

     

    Both the Murdoch and Fairfax press are certainly going after the Liberal and National members.

     

    The Labor initiative to reduce the majority by having members who were technically born elsewhere backfired somewhat but still reduced the majority compared to other Parliaments. Ironically the first Labor Prime Minister was not entitled to hold office but it was kept quiet.

     

    The press has pretty much made sure the polls are uniformly bad by attacking each new Prime Minister from the day he was appointed, disregarding the fact that they have only been able to govern by doing deals with the independent parties, with the result that legislation is prostituted instead of reflecting Party policy. You could argue that it would be more honourable to call an election to get a decent majority

     

    The press did the same with the Rudd and Gillard governments.

     

    They were only able to do it because there were base faults and infighting there.

     

    It's likely to start again on the Labor Party in Victoria where the OPP is currently deciding on whether to prosecute up to 29 Labor Members of Parliament and/or staff for allegations around using taxpayer funds for an election campaign.

     

    While all this may be very exciting for some people it's leaving Australia's trail of Federal Government looking like the result of a drunken dog piddling down the street.

  5. But how is that different to Christian Scholl, the arsewipe who drove his B-Double into the side of a passenger train at Kerang and killed 11 people. The only substantial difference, is Scholl drove that route weekly, for 5 years and knew the level crossing was there but still drove at a speed that meant he couldn't hold short of the stop line when he observed the crossing lights were activated and his actions resulted in the worst rail accident since Granville.

    Sometimes I wonder just how 'justice' is served...

    We can't compare cases at this (forum) level because we don't have the legal qualifications, and we were not in each court room to hear all the evidence.

     

    For similar reasons we can't extract from the news reports why a pilot who was charged with descending below 500 feet above a river was charged with manslaughter but found not guilty.

     

    What we can do with the bus case though is look at what happened to the driver and why, and perhaps touch up our navigation and observation skills for when we carry passengers.

  6. This was followed immediately by various versions of how to avoid your civic responsibilities, which would be good reading for the insurance industry, but the significance of this case is your obligations to your passengers. This person was sentenced to five years for injuring his passengers.

     

    The key theme were his navgation failures, and his failure to observe a hazard, things relevant to most of us in flying.

  7. And not only doctors. I knew a guy who had repaired gliders. Those gliders could still involve him in a liability payout even though he is no longer insured and no longer in the business.

    This is a very common situation; a mechanic retires and five years later a car he worked on is involved in an accident due to not following the manufacturer's safety procedures etc. 

     

    Jaba Who explained the clause a few posts ago.

  8. They interviewed the doctor, who was fairly old, they  showed the sign and interviewed a couple of patients, one of whom was staying and the other one was going to move elsewhere.  Doctors pay horrendous premiums I think, and our local practice ceased doing births because of insurance costs.

    With respect to aviation, I wondered if the club here could somehow transfer its legal  liability to a renting pensioner  we had as a member at the time.  Nothing came of that, it was just some idle speculation on my part.

     

    About that time, there was a flurry in the news when a surf-lifesaving club in Adelaide announced they were going to close down because the committee of the surf club were told that they were risking their personal property in the event of litigation. In response to this, the state government passed some legislation which I think fixed the problem, at any rate the lifesaving club didn't close down.

    You can't hand off a Tort; that sign wouldn't have helped the doctor evade his duty of care.

     

    The surge in governments handing control of sporting and volunteer organisations started in South Australia with deaths at a kindergarten, so the most likely thing the government did for the lifesavers was advise them to tale out event-based public liability insurance. We were paying $1000.00 per meeting and were back in business before we physically closed any tracks.

  9. Sounds like more obfuscation to me; I'd suggest they are the locations of Jabiru dealers around the world.

     

    This thread was about an experience in Australia so there's not a lot of point in beating up overseas products where nothing really stood out as a cluster.

     

    Including production figures is a waste of time since many of the older engines which reached TBO,  and were replaced have to be taken out

     

    Many of the older aircraft have long gone to the tip and have to be taken out

     

    Every engine which failed and was replaced by a new one has to be taken out

     

    The overseas engines which had no problems has to be taken out

     

    This thread was about problems a person had in Australia, so it's a question of how many Jabirus are operating in Australia

     

    The public statistic is that RAA state that there are almost 3500 registered aircraft. They did NOT say 3500 Jabirus, so you have to take away all the other makes of engine before you get to the number of Jabirus registered in Australia, and that is the group that would have any personal interest in the status of their aircraft today.

     

    And the bottom line about that group is that we are not seeing any reports about the new engines failing on the trip down from the factory, or failing full stop.

  10. Almost 3500 would suggest that of the 6900 Jab engines quoted at least 3400 Jabiru engines are either overseas in places like USA, South Africa and Denmark or not in use.

    When I mentioned that the 3500 was ALL aircraft, that meant that there are substantially less than 3500 Jabirus registeredin Australia so your "overseas" quota goes up exponentially to illogical levels.

     

     

  11. That might suggest that some Jab engines are OS in places like USA, South Africa and Denmark.

    The "almost 3500" is all aircraft including rag and tube with two strokes, Rotax powered aircraft and a variety of others. 

     

     

  12. Would (should?) the Board have had a say in this? If so surprising that someone didn't ask the question whether the proposal was legal given that most members indicated they didn't want their details revealed. Anyway - how do we get this reversed? Do we individually write to RAA confirming that we don't our personal  details revealed ? Other suggestions?  Thanks,  Bill

    The "Board" is now a board of directors, no longer a board of management where the board members managed an association day by day and communicated with the members.

     

    Most companies communicate with their customers through the CEO, Managers and appointed officials.

     

    Directors usually show up at board meetings and look at company performance for the period, e.g. monthly or quarterly; they may call a manager in to the meeting to explain something, but that's about it.

     

    So as much as the new structure has thrown up problems like this, the directors haven't deviated much from what would be expected of them.

     

    Remember, many people have said on this forum over the years, "I only want to fly", and the famous words of one contributor; "No sense having a dog and barking yourself"

     

     

  13. Around 6900 of the old engines are out there, Id say largely still unmodified and therefore still under casa limitations if in AU

    Brand me uninformed if you wish.

     

    RAA report "almost 3500 aircraft" registered; says it all.

     

     

  14. Turbo said.

    Which list are you referring to?

     

    (a) The data obtained by CASA employees who visited RAA facilities and collected it?

     

    (b) The list supplied by a person within RAA some months later, which contained items such as fuel exhaustions, which clearly were not engine failures, and was quoted publicly by the CASA Public Relations officer?

     

    It was reported on the Pro Aviation website at the time (28 November 2014) in an article entitled "Indecent Haste" written by Paul Phelan & stated that an unedited list had been obtained from RA-Aus.

    That was the list referred to in the cat fight about the Instrument; the list was produced by someone within RAA, and used by the CASA spin doctor. If you cut 10 out of it to allow for fuel exhaustions, flat tyres etc. you'd have 30 for the period, which was exponentially above the levels of Continental and Lycoming for the same period. It was en emotive list and only a few people contacted the CASA SAO operations people to find out that CASA had sent two specialists to the RAA office some months before to go through the records and get their own statistics. It wasn't their fault that others screamed about the iniquity of the other list on this and other forums. 

     

    I posted a list taken directly from the RAA magazines from February 2007 to March 2012 focusing only on reported forced landings/aircraft unable to take off again which showed 12 due to exhaust valve, 7 due Thru Bolt, 5 due seized/Con Rod/Catastrophic = 34. On top of those would have been Unreported, and incipient failures found during inspections, well above Continental/Lycoming.

     

    During that same period, three Rotax 912 forced landings due to mechanical failure were reported. They were Circlip Oil Pressure, engine failure, no cause specified.

     

    Later someone tried to colour the story by including small two strokes in the Rotax figures.

     

    RA engines would not have an expectation of meeting the same TBO performance as Continental/Lycoming, but as people were starting to use them for GA application like cross country flights with passengers, an engine comparison started to become relevant.

     

    Jabiru resolved the issue, as many car manufacturers have done, by designing a new engine, and that appears to have been a good move because we are not seeing reports of forced landings and engine failures.

     

    While this may have blown the budgets of owners of the older model engine owners they could put a new Jabiru engine in and still achieve about the same cost as a new Rotax.

     

    This thread should have been locked when the improved performance of Jabiru's new engine became apparent, and it's unfortunate that people have started talking about a situation which no longer exists; a bit like chatting about the Holden grey motor.
