  1. ..... it is a little known fact that Jerkov is a quite common name. 

     

    There is one in Tasmania and there used to be one in WA before he resigned from the Board.

     

     

     

    But I digress, because the Lower Kumbukta West CWA Netball Team is well known for their ...................

    extremely short skirts, which are a bit horrifying as they are a men's netball team. As Rattso tried on a set of bike shorts, a gigantic Lightwing (seen before on this thread, coming to a thread near you soon) roared over the Central Bludgeness District of Cantborough, where...

     

     

  2. Just last week I was given a budgetary quote to factory-rebuild a timed-out R912 80 HP at between 16 & 17 thousand. Picked myself off the floor, took three nitroglycerine tablets and requested a new price on the same unit. Immediate reply - $18 thousand! Have to guess that management policy of selling new engines for a few points more than a rebuild keeps their factories working. Anway, who needs economy - it's aviation, and everybody knows we're all rich! cheers Riley

    Struth! well I know I'm rich, that's why I know about 503s... and Thrusters...

  3. Thanks Bob,Good useful information that!

     

    Sorry for the Thread Hijack Robert!

    No worries. The Rotax lifing is mainly based upon the very variable life of ball bearings, but modern synthetic oils - esp. methyl silicone - and keeping the throttle either fairly open or quite closed seems to beat that.

     

     

  4. A points-ignition single carb, with good oil and a wooden prop that doesn't hum, can see 600 hours with good compression and minimal play on the bearings - haven't gone past this. A dual-carb (solid state ignition) in a two-seater will go at least 500 hours, if you keep the throttle well open. If you treat it like a 4-stroke, you can get bearing problems before the compression gets low...

     

    Be aware - I have not racked up this amount of time on my own; it's a combination of the second-hand aeroplanes with known histories I have/use, and the records of TOSG on which I base this advice.

     

    The 582 with good oil, in the right hands - even in training use - can go 1,000 hrs; but your warranty will be void!

     

     

  5. It's a scratch build of a prototype eighty knots and I'm not up to date with the terminology such as starboard & port guys. So if someone wants to let me know the right way to describe stuff I'm happy to receive that knowledge. By the way I'm a "she". It is also the first time I have built anything although I've flown a few different types of planes.

    Port has four letters, as does left - this works for me (one, two, three, four, lots... 002_wave.gif.62d5c7a07e46b2ae47f4cd2e61a0c301.gif)

    Port wing, left wing, left hand lifting surface, that wing there... working with aeronautical engineers - and as one, if out of Qld - all these terms are correct...

     

    Congrats on actually getting the metal together, it's taken me decades to not start building my own!

  6. So what would a 912's timex be, 1500 hrs??

    depends on the model.... earlier ones were shorter... not sure at which model the life went up from 1,200 or so...

    I run my 503's "on inspection", with plenty of inspections! But not in flying school use... 082_scooter.gif.e6a62d295b0b59b8276038871473d864.gif

     

     

  7. Hi AllJust wondering what a time expired 100hp 912 rotax would be like to use in a 50 to 80 hrs a year aircraft

    Worth it or not any info on this matter would be good

     

    Cheers

    I know a few people who run them until the compression is too low for easy cold starts or to the mandated life, whichever comes first. Generally it's the rings that lose compression, and rebuilt in accordance with Rotax specs, a 2nd life engine is - not new, but a fair bet. Not cheap, mind... As Nev said, a fully overhauled engine has old bits in it. 3rd life (overhauled twice) Continental 6s, and a few Lycs I think, have blown barrels off the case due to crankcase overaging... amongst zillions of engines...

    i'd be willing to run a time-ex 912 VFR by day, if I could get it to start! For a while, anyway...

  9. They should have been paid $2, not have to pay it - The Government needs to support the rich in order that they can create and substain micro economies instead of punishing them for creating them.But the poor won't support that because the rich are bad, they must be, they are rich after all and seeing that the majority of the people are poor they won't accept a Government that doesn't side with them, so the Government must be seen to be punishing the rich for being rich and in the end the poor simply get poorer - but they are happy because those rich bastards are getting punished.

    The bottom line of your first comment being, that the businesses with which they are involved tend to pay lots of both tax and wages. Yes and amen.

    Your second comment, re Aussie perceptions of financial elitism, can stand for itself - an element of that attitude is manifest, although there are other factors of course.

     

    I suggest that neither the ethos nor the fiscal sense of adjusting the private-government financial relationship such that the change takes, proportionally, more from the poor than the less poor, appeals. In gross terms the saving is small, and in proportionate terms if the saving were spread as an equal proportion of income over the whole spectrum, the more wealthy (or higher turnover) individuals would not have a diminished quality of life. Combining the farcical exaggeration of the budget "emergency" - what we have is an attitude problem that has directed the economy in a long-term unsustainable direction - with a non-egalitarian tightening of belts, there are a lot of wounded sensibilities.

     

     

  10. THE TAX SYSTEM EXPLAINED IN BEER.

    When pondering the question of mining super taxes and the structure of our tax system in general please refer to this explanation using the language of Beer!!

     

     

     

     

    Suppose that every day, ten men go out for beer and the bill for all ten comes to $100.

     

     

     

    If they paid their bill the way we pay our taxes, it would go something like this;

     

     

     

    The first four men (the poorest) would pay nothing.

     

    The fifth would pay $1

     

    The sixth would pay $3

     

    The seventh would pay $7

     

    The eighth would pay $12

     

    The ninth would pay $18

     

    The tenth man (the richest) would pay $59

     

     

     

    So, that's what they decided to do.

     

     

     

    The ten men drank in the bar every day and seemed quite happy with the arrangement, until one day, the owner threw them a curve ball.

     

     

     

    "Since you are all such good customers," he said, "I'm going to reduce the cost of your daily beer by $20". Drinks for the ten men would now cost just $80.

     

     

     

    The group still wanted to pay their bill the way we pay our taxes.

     

     

     

    So the first four men were unaffected.

     

     

     

    They would still drink for free. But what about the other six men - the paying customers?

     

     

     

    How could they divide the $20 windfall so that everyone would get his fair share?

     

     

     

    They realised that $20 divided by six is $3.33. But if they subtracted that from everybody's share, then the fifth man and the sixth man would each end up

     

    being paid to drink his beer.

     

     

     

    So, the bar owner suggested that it would be fair to reduce each man's bill by a higher percentage the poorer he was, to follow the principle of the tax

     

    system they had been using, and he proceeded to work out the amounts he suggested that each should now pay.

     

     

     

    And so the fifth man, like the first four, now paid nothing (100% saving).

     

     

     

    The sixth now paid $2 instead of $3 (33% saving).

     

    The seventh now paid $5 instead of $7 (28% saving).

     

    The eighth now paid $9 instead of $12 (25% saving).

     

    The ninth now paid $14 instead of $18 (22% saving).

     

    The tenth now paid $49 instead of $59 (16% saving).

     

     

     

     

     

    Each of the six was better off than before. And the first four continued to drink for free. But, once outside the bar, the men began to compare their savings.

     

     

     

    "I only got a dollar out of the $20 saving," declared the sixth man.

     

     

     

    He pointed to the tenth man, "but he got $10!"

     

     

     

    "Yeah, that's right," exclaimed the fifth man. "I only saved a dollar too.

     

    It's unfair that he got ten times more benefit than me!"

     

     

     

    "That's true!" shouted the seventh man. "Why should he get $10 back, when I got only $2? The wealthy get all the breaks!"

     

     

     

    "Wait a minute," yelled the first four men in unison, "we didn't get anything at all. This new tax system exploits the poor!"

     

     

     

    The nine men surrounded the tenth and beat him up.

     

     

     

    The next night the tenth man didn't show up for drinks, so the nine sat down and had their beers without him.

     

    But when it came time to pay the bill, they discovered something important. They didn't have enough money between all of them for even half of the bill!

     

     

     

    And that, boys and girls, journalists and government ministers, is how our tax system works.

     

     

     

    The people who already pay the highest taxes will naturally get the most benefit from a tax reduction.

     

     

     

    Tax them too much, attack them for being wealthy, and they just may not show up anymore.

     

     

     

    In fact, they might start drinking overseas, where the atmosphere is somewhat friendlier.

    For those who understand, no explanation is needed.

     

     

     

    For those who do not understand, no explanation is possible.

    sigh. simplistic. ever heard of tax minimisation? 75 of the top hundred richest people in the country paid an average of under $2 in tax... google it... but they're taking 10% of the beer away from those who drink for free - bast***s!

     

     

  11. Riding motorcycles and flying is often combined. Sir Jack Brabham wanted to be a pilot in the airforce, but still ended up flying his twin engine thing( Think it was a Beagle) for thousands of hours all over Europe. Graham Hill (father of Damion? Hill was killed in his light plane.trying to land in crook conditions. Lionel Van Pragh was a good speedway rider. and excellent pilot. When TAA started 1947? quite a lot of pilots rode motorcycles to work but that was a bit frowned upon although I earned more money in a blast furnace firebrick factory at age 15. (Newbolds General Refractories) in Newcastle , than a DC 3 Captain did in TAA at the time, so I wonder if they could afford a car.. Not a lot of Motorcycles around aerodromes these days. I think you need similar skills and reactions for either. Nev

    sense of spatial perception, perhaps...

     

     

  12. I like checklists too, But simply reciting the correct responses and NOT noticing that there is a problem HAPPENS. Self discipline is the KEY. Boring but safe®.. Nev

    I never check the undercarriage position indicators on ANY thruster... Boring lasts. Excitement can be nasty, brutish and short.

     

     

  13. That may well be, but they are all dead now. I think the mainbearing shells moved in the tunnels and scratched the radius's causing shaft failures. It's all on record. Some think the pilot and company were given a hard time by the authority, but they went out of business, I think. There is a bit about the engine faults concerning the maker. There is always something to get from reading about these happenings. IF there are indications the engine is not right, (noises vibrations loss of power, oil pressure etc) get it on the ground. If you are on fire do it even more quickly. Nev

    go the Do-X. Or even the dreaded 7-engine approach in a B52? with one out... surely a fire will get you to the ground quickly, one way or another? 032_juggle.gif.8567b0317161503e804f8a74227fc1dc.gif

     

     

  14. You PROVE it. That IS a fact. Rather than HOPE it is.. IF you check that the tank is full then you don't have to believe what someone else told you. OF course if you use an engine I built, you would have to accept on trust or expectation, that I have tensioned all the bolts correctly amongst other things I should have done right.. Nev

    scientific method in action! I had a deep philosophical argument this morning, so post 29's simplicity attracted my wordplay. That said, I have reservations about "prove", too.

    I like checklists...

     

     

  15. To which I have invented a very important and new acronym for all pilots....M.A.C. Marital Aviation Clearance. Absolutely imperative to avoid AIDS ( Aviation Induced Divorce Syndrome).

    Or. a Big MAC if it's really important!!) Boy I'm Grateful.

    How about: A Real Pilot is always aware of the full situation, and has an exit strategy?

     

     

  16. Thanks. Shall do.

    Newcastle TAFE have the 4th edition in their library. The bit Dafydd didn't mention was that enriching the mixture up to ~125% of chemically correct increases the resistance to detonation a lot - see also post 18 - and the power a little (I have both of his copies of Ricardo, heh heh...)

     

     

  17. "No Way!!" said Andy "The lightwing defence will never fly in this case, and indeed not many others as well, because"................

    ...he's not bluddy safe, he's DEAD!' "Dead safe, eh?" drawled Ben Tley, who could be found wherever gin was being served. "Look, in a legal situation the facts are secondary, look at the way aviation is regulated for heaven's sake!" he went on. "This dude is grounded, so he's safe!". Rat lightly elbowed him in the face. "I hate to admit it" he growled, "but the pom...

     

     

  18. from CASA who wanted to breath test Madge jest for toad toxin....

    "We are a strict liability organisation, when we have a rule about something and you break it you're strictly liable and will cop a fair old wallet walloping. When we don't have a rule about something its up to us to make one up or point you at one our completely unintelligible rules, tell you that one disallows what ever it is that we think your doing wrong and again you will cop a fair old wallet walloping proportional in severity to how much whinging you do. So lets get a mouth swab done to test for toad toxins cause if you have any of those we want to keep you from flying....at least aircraft flying"

     

    But Madge used toads like popeye used spinach and the poor dude from CASA was quickly..........

    dissolved by the intensity of his breath. Madge stared in guilty horror at the spreading puddle of blubber and blood. Rat punched him lightly on the shoulder, and said...
