Excuse my ignorance.....how do you have a cylinder head with valves on an OP engine?

No problem, everything can't be everyone's field of expertise heres a crayon drawing for you ...

Happens all the time over here, if you want to make an effective statement without damaging people's cars, lift their wipers up.

BTW, I've been accused of parking like that when in fact I squeezed into a gap between a bunch of motorcycles and they left before me so it's not always what it seems.

The Jabiru is centre stick, so fly left seat right hand, where as the Alpi is duel stick, left seat, left hand....

I also worked many years ago in British bike shop, after a while it became second nature riding a Norton with rh gearchange and reverse pattern compared to a Triumph with rh gearchange and most other bikes with lh gearchange. You barely think about it after a while going from one to another.

Stay tuned for coming anouncements on Australian airframe kit projects .....

I mean if one makes engines, one should have a plane to wrap around it too shouldn't one .....

Thanks for the first hand reports xair, hope it works out well for you.

So, even though the existing engine was fine, for no other reason than they wanted to, they gave him a new engine?

and hemispherical combustion chambered heads would be rare in aero engines.

SDS is a great multi piont FUELINJECTION system and Ross is a great guy to deal with . The difference it's makes to smooth running is to second to none , coupled with liquid cooling , seems to be the way to go ,

Yep, Ross came to visit me personally in China to sit down and discuss it, he is very modest about his knowlege and abilities. He has a nice EFI package for the engine including wire harness and instrument package, looking forward to working with him on it.

This country is losing its ability to manufacture many things giving the Chinese a monopoly that will come back to bite us in my opinion.

Yes, I used to wonder around a number of engineering workshops that had amazing variety of machine and skills as a kid in the 60's with Dad and go to Repco with him where he would order custom pistons for which ever race engine he would be building at the time (Tasmania made the pistons IIRC). It is sad.

Bex depending on the rpm range there would be little advantage in double overhead camshafts and 4 valves just a weight disadvantage.

Well there a little advantage but the thing is it's getting harder to get off the shelf SOHC 2 valve heads. Anyway, I not only have one it also runs it's own distributer from the cam forming my second ignition system which has made life very easy and cheaper maintenance for the client.

You should do what us race car blokes do, grab a handful of spanners and go run them over every nut and bolt you can see, it only takes a few minutes and it's surprising how many look sound but are just sitting there, just waiting ....

oops sorry

So, is that a three barrel 'common knocker'?Going to run on diesel?

Rootes blower or turbo?

I love the Commer Knocker for it's eccentricity and the smoothness but no, mine is a 4 stroke and no turbo, at least for the first model anyway but have the right guy for that work, my EFI guy (if all works out well), he is Canadian and in Canada so at least keeping it in the Commomwealth!

and Ross is a Flyer too ... http://www.sdsefi.com/air9.html

Look at how smooth OP engines are (Commer Knocker)

"all the energy for that we stole from the atmosphere"

I knew the minute I saw the long hair, scruffy beard and pony tails that I was looking at oxygen thieves!

It needs a good european sounding like das thunderbolt

tHE AVATAR SHOULD BE GONE ON sEPTEMBER 14TH.

Damn you Caps Lock.

I would laff but your avatar is creeping me out !! ...

So will the bexmetter fit in a 912 cowling?

That is a standard, modern, 'sold in the millions' SOHC 2 valve head sitting on top, available worldwide as are head gaskets etc. I've mentioned before that it's not just a cheap engine to buy but more importantly will be cheap to own long term. I wanted to go DOHC and 4 valve but there is certainly a resistance with flyers to move forwards too quickly.

Note that the water cooling on mine is centralised, ie; the head and immediate block under it, and eliminates the need for mutiple connecting pipes as the Rotax needs to use.

I don't believe I've bagged the idea. Just pointed out a few things that have actually happened. Several largish companies have had bad experiences too. The Chinese play the game their way. They are hard working people who deserve success. Good luck to your project Bex. You have certainly made some claims and gotten out attention .Low volume production numbers don't make for low unit prices and aero engines are expected to keep going. It's a hard market and plenty of big names haven't made it. Porsche, Bugatti, Rolls Royce don't make Continentals now, Rotax are not making most of their long running two stroke range. Nev

Caterpiller just got $600 million taken out of there pockets here, idiots. Bet the same mangaement and lawyers are still working there next year though ...

As you say the Chinese play it thier way and the biggest failing of Westerners here is their own arrogance, firstly thinking they are superior in business to a backwards country where you still see old woman carrying a couple of live chickens from market to just simple believing they have things in place and that's how it will happen - it's a laff a minute watching them 'control and direct' a business meeting when you know whats actually happening with the Chinese just politely nodding and agreeing ..... history shows what a savage ruthless place this is to do business, it's not just round eys, it's anyone, I have seen brothers, sons, even 60 year old mothers take family members out (my wife put her in jail btw).

No claims from me, just a process, I have stated nothing more than what is happening and what I know can be done following the process - the Chinese process.

I myself like the idea of the Subaru Diesel or a copy, it would make a great aero engine if it could be direct drive to reduce weight. What do you think ?

Give him a chance if he is successful I bet you will all be lining up to buy one.

The very few engine manufacturers, Lyc, Rotax, etc, have the market to themselves and are strangling you guys for all you're worth, I have some hope I will make an impact on this forcing them to rethink their arrogance and of course their pricing.

Anarchy I say!!

My 1998, 2003, 2008 and 2009 Toyota's all made in Japan, thanks very much, just the way we like them.

You have no idea what the Chinese content in your cars is do you.

There are people who have lived here in Australia for less than ten years call themselves Aussie, and for mine they are more Aussie than your engine!

They produce to your specs right up to the point you take your eye off them and trust them to keep doing it. The most important specs over looked in most chinese copy-facture is the metallurgy.

Does the fact that Rolls Royce, Boeing, Cessna to name a few aeros let alone Mazda, Honda, Toyota, Audi, Benz etc manufacturer here not suggest that you might not be quite up to speed with China? I bought my brand new Mazda 6 in 2005 made 100% in China and it hasn't had a single fault in 220,000kms on Chinese freeways at 140kmh or over bad Chinese mountain backroads and almost always 4 adults up (and a chicken ).

As for management, I have lived here for 10 years and it's MY FACTORY. It's also my design, my QA and my QC. I have complete control over the lot.

I'm not trying to kid anyone or hide anything, I am making them in China to be competitive on the world market but the project is employing Australians, 6 to this point, and the bulk of profits (100% from Chinese investment btw) are going to Oz and I am very proud to call the project Australian.

Libelle is the word

So what your saying is that this new engines going to work and stay working straight out of the box , I wonder if you'll have to eat your words (for how long?)in a couple of years or so ,

But fair question anyway - I am slowly gathering components and intend for 25 engines to be both bench tested to death and appointed to various flyers for testing in various configurations.

I won't get into Jab engines other than to say I am looking heavily at cylinder head solutions for them.

Its 6 cylinders not 4. .

Sorry

His words were "you get what you pay for". So dont complain when the fan stops prematurely.

I couldn't give a hoot what price mine come out at, there's no way I'm suffering the responsibility of the death or injury of a person without doing everything humanly possible to avoid it.

There's cheaply made and then there's cheaply made, I will not confuse the 2.

Jab engines are considered cheap. .

Anyway, best of luck to them, they put their money where their mouths were..
