Old Koreelah

... despite having spent over 1500 hours building my aircraft (including an engine conversion) I am not to be trusted to understand it enough to be allowed to continue maintaining and inspecting my creation without passing an exam and having to arrange for an L2/L4 inspection. Surely some form of recognition of prior learning should be allowed for...

Sometimes it's easier to actually start from scratch and do the course than get Recognition of Prior Learning.

Andy - yep, that's the inhibitor squirter set-up, but they actually inject into the inlet port just ahead of the inlet valve so the (warm engine) oil hits the warm valve face and gets sprayed around the barrel. I believe CAMit are still testing ...

Next time you get into a dogfight, you might be sorry... 3~4% can be the difference between victory and defeat!

...reducing the outlet area as a nozzle should give a bit of "thrust", provided you don't increase the positive pressure field around the inlet. Anyway, reducing the cooling flow certainly reduces the cooling drag.

I removed the augmentors. The 3-4% extra efficiency was not worth the damned noise.

I used Instamapper with success for years but it seems to have been dropped. Have used Glympse recently, usually with success. There are other free aps, but many seem designed to secretly track cheating partners. Maybe OzRunways could add one.

Bob years ago you got me thinking about this issue. Any low-wing can dump engine cooling air into the low-pressure zone above the wing leading edge. Mine does and the heads run so cool that I have been incrementally reducing the inlet area.

Harking back to the post that kicked off this thread...

For me the fun has just begun. After years of building, testing, modifying and retesting, my aircraft is performing very close to my ideal. I can fly interstate in the silky smooth air above the clouds, land in a paddock, camp under the wing and get together with like-minded people. I can do most of my own maintenance and it costs less than keeping my bike on the road.

Yesterday I discovered another motorcycle parallel: while cruising hands-free, I can steer it with slight movements of body weight.

Yes, good idea Keith. Then she'll want me to get a two-seater. More expense!

Warning: the hidden cost of attending Natfly could be exhorbitant!

My trouble and strife has welcomed me home with the observation that, since I had been enjoying so many trips away, it was now her turn.

She wants an all-expenses trip to a quilting camp, and because I've been to ten Natflys, she's going for ten bloody days!

What's numbers got to do with how much you enjoy a gathering of like minds and their planes?

Sure there were far fewer aircraft, but it was also less hectic with less traffic to negotiate when arriving.

I was pleased to see quite a few families visiting and camping. Who says we're a dying breed? In the camping area I saw a couple of big screens showing kids an appropriate movie: Planes. There were also a few forumites present.

It was great to meet up with familiar faces and make new friends- and talk about something other than bloody footy.

Nice work OK. What sort of engine are you running?

I guess the best design features are found in the most efficient aircraft. Especially the ones which don't use brute force to get thru the air. Another overlapping thread has some very slippery sailplanes, and some of those use filleted intersections.

Birds have gentle, organic curves at all intersections. That's the result of an awful lot of development.

Actually, the old Jodel may suit having 'pants' ah lah Chilton Monoplane?[ATTACH=full]27943[/ATTACH]

Choose your own colour arrangement...

The Chilton looks sleek, but those angular intersections are the enemy of smooth airflow.

That's a pretty impressive "least impressive"... :)

... can they be successfully fitted to the wing surface?

After spending a couple of months building fairings around my fat 600X6 tyres I finally got to do some proper tests today, flying extended squares at 4000' with and without the spats.

In the least impressive test, while cruising at 2900rpm fuel consumption dropped 8.95% and speed increased 6%.

I never particularly liked the look of those ugly big wheel pants, but they work.

Some good news for people using Jabiru engines. This kit is inexpensive and it doesn't take long to install

I just found out how good it is. I always hand-turn the donk at least ten blades to get the oil flowing and check compressions. To save weight I use a tiny battery (Deka 120 CCA). It's getting old and weak and this morning could barely turn the engine over, so after the first couple of laboured rotations it looked like we were going nowhere. I made a forlorn 2nd attempt and she fired up. What a great improvement!

As Molly used to say: Do yourself a favour...

...No one has addressed what caused the situation in the first place. If you don't believe me just watch what happens in the next five years.

Still, I hope you are wrong; my kid has finally committed to buying their first home.

STOP PRESS

Those people denigrating lawyers should apologise. They are not the lowest form of humanity. I am watching "Inside Job" on GEM. We knew there were some dodgy things being done by investment bankers, but the scale of their scam amazed me. Their mates in the US government had deregulated their industry, giving them a blank cheque to make money dishonestly, create economic chaos, get bailed out by the taxpayer and somehow not only keep their ill-gotten millions, but avoid liability for the global crisis their greed caused.

What a bunch of parasites.

Maybe someone can help. An off-roader group is planning a trip to locate an old aircraft wreck in the Barrington Tops area.

They need much more info; all they have is

http://www.atsb.gov.au/publications/investigation_reports/1976/aair/aair197601498.aspx

Any more info would be appreciated. (Yes, they will also keep an eye out for the plane that was never found.)

Here's a photo for you all, where we are both looking! Got them back from our photographer a couple days ago.Thanks again everyone!

 

In any legal court case there can either be:-...why in some states of Australia can people who buy real estate use a conveyor to facilitate the legal aspects of the purchase, where they are then covered against a professional mistake with appropriate insurance....and in other states like in NSW you must use a solicitor. Where at least on the small amount ive been involved in, it seems that the costs for the later are significantly higher than the conveyor approach and the work done by the solicitor was in reality done by a law clerk...... Never understood that myself.

I agree, GG. My experiences of lawyers have not been encouraging. There are still a few who deserve respect, but they are unlikely to be wealthy. I have grown quite skeptical of the rich; to get there, so many have by-passed their conscience.

Despite my prejudices, my kid and her hubby are both law graduates. (In their defence, they are on the side that puts bad guys away.) Like so many, they have other specialties but need a law degree to do their job properly.

How ridiculous the law has become when it takes years of study to get a basic working knowledge if how it works. This is a result of lawyers contriving clever ways to get around the rules. The government eventually tries to plug each loophole with complex legislation.

The Tax Act is a similar case; the printed version requires a forklift. The underlying problem is that we apply the LETTER of the law rather than the SPIRIT of the law. We all know the difference between law and justice. Maybe Iran is on the right track (but unfortunately they are limited to what was considered justice among desert dwellers fifteen centuries ago).

I'm with Tracktop. What's the use of having the gear if you don't use it religiously. Even bowzer AvGas has to go thru mine before it gets to my tank. I carry a medium-sized Mr. Funnel with me. I added an extension tube which fits into the wing tanks, and a folding arm which hooks over the edge of the cockpit.
