I think HHE drink all their beer for safety purposes...

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...

The Cherokee 2 soaring on the row of poplars at the end of Bathurst strip; the noise of a Tigermoth tug; back-seating the club's 125hp supercub tug; all those big white gliders...

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

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.

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!

My brother and I tested our ability to read a clock with the toy clock at Bathurst aerodrome... the one that told the gliding club when the East-West F-27 was due. Put me off clocks for a while...

Port has four letters, as does left - this works for me (one, two, three, four, lots... ) 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! -
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...

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...

...that sexy bloke? Oh..." As she saw it was just Madge. Ben, cravatte elegantly held to his bloody nose, sidled up and molested her - but her legendary left elbow did its thing, and...

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.

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!

sense of spatial perception, perhaps...

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

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?

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...

you believe that?

I've seen some pretty thumpy eagle landings...

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

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...)

how 'bout a 12-engined seaplane!!!

...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...

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...
