I will be in Goolwa for a few days soon, time table not clear, anyone here there?

Just luck of the draw I think, use the card for payments on the net a lot, never had a problem, had a Mate who used his once and $5000 got spent in the UK on it a few hours later.

You're not going to get potato cakes and a piece of flake that's for sure. Take your craft's security and personal safety seriously in some of the outback towns, there's a lot goes on that doesn't make the media.

That'll take off.

At least you can spell 'owyagoin' properly.

Oh yeah right, go price some Rotax or Lycoming parts I owned mechanical repair workshops in Logan, a demographic that owned lots of old dungas and never had problems buying parts for anything. Stick with the weight and water cooling hassles for automotive engines, it's the only arguments against. Actually the Fox is within reasonable limits for RAA craft.

And all these years I thought his name meant beans.

When I started my motorcycle club many warned me against big bad Motorcycling Australia, couldn't have been further from the truth, MA were just great, and very flexible helping me to establish my targets. So as yet I do not carry a personal opine on CASA and will stay open until I have had experience with them.

I have no problem working with Governing bodies who are reasonable people. I had a great working relationship with Motorcycling Australia (MA), and on the other hand, had input into helping an opposing body against the Confederation of Australian Motorsport (CAMS) who liked to believe they could dictate, and in short time found out under Australian Law that they could not, hence the birth of the Australian Auto Sport Alliance (AASA). The problem with CAMS was they were paying too much attention to the upper end of motorsports, V8 Supercars, F1 etc, and forgetting about the little Fella, while using the little Fella's money to cater for the big boys. The little Fella's struck back with their own Governing body, and all of the FIA and CAMS might couldn't stop the basic legal right to Govern one's own sporting body with members in Australia. The AASA actually deferred motorcycle licences back to MA last year because MA are flexible and will work with others. Other Australian Sporting Governing bodies have also found out in modern times that they wield a stick far shorter than they think, especially when it comes to Professionals earning money under other Governing bodies (as CAMS famously found out in Court with Peter Brock). I have had no dealings with CASA personally to form a judgement, and this is not aimed at them, just a note that you're not as helpless as you might think.

The 'Pickurplace' Lions Club annual sausage sizzle charity fundraiser held at 'Pickurplace' airport is not a Fly-In. It's just a great event to support conveniently located at an airfield.

I want it to be clear to the whole forum that I didn't go anywhere near, or had nothing to do with his balls otherwise.

Not sure of the relativity here, if you want F1'ish power up front then you need to go no further than a Hartley, Synergy or Powertec V8. https://thekneeslider.com/hayabusa-v8-grows-up-28-liter-455bhp/ Hartley Enterprises' Haybusa-derived 2.8L V8 SYNERGYPOWER

What "Air Display"?

It's all a bit confusing, Zenair, Zenith, Zenith Air, AMD, Newplane, all the same company basically, not sure why all the run around.

Zenair to be exact. Mid 90's CH2000.

No problem at all, all modern engines will run full load for as long as you want. The durability test cycles for modern engines undertaken by most manufacturers now are well beyond the aircraft engine certification standards. This is constantly stated as an anti-automotive engine argument with no evidence to back it up. Some hypocrisy as well because many people who post these falsehoods then go jump into their modern car and enjoy all the fruits of those durability tests. "Oh but I only use 20% of the engine in my driving", yeah but you live in Australia, go to other countries and see how they treat cars.

I am unaware with the 230/430 if you can move the engine back much or not, firewall mods, etc. If you have to start adding excessive weight in the tail, etc, sure it may not be worth it if the craft ends up a pig in the end. Jabiru are obviously locked into their own engines and do not cater for others, unlike myself, so conversion may prove too difficult. Note at 5000 ft the Jabiru 3300 is losing 20% power and only making 100hp at full noise while the Honda is still maintaining 100%, eg; 170hp. Clearly we are all quoting manufacturer's peak hp claims. Note the argument for any turbo engine is even stronger for continuous power, as full boost can be obtained at most any rpm. Ahh, so finally you are adding what the weight is relative to that you are against. It is not a heavy engine at all as I have shown, it's just too heavy for your particular purposing. Well then you all look silly, it's a stock standard 174 hp Honda Civic engine mass produced by the tens of thousands. It's also 194hp rating in the Accord, and 205 hp in the Civic Si model. Maybe some of you thought Viking was "home turbo'ing" their 130 themselves, nope. And it's not even particularly powerful by today's turbo standards, try to keep up, it's 2017. So, you would rather a Toyota diesel than the Suzuki in a Jabiru? ... Allow me to offer some physics and math. Toyota max torque = 260 lb ft @ 2700 rpm Suzuki max torque = 100 lb ft @ 7000 rpm, reduction factor of 2.6 = 260 lb ft @ 2700 rpm. The fact is the Suzuki has the same torque as the Toyota when output shaft speed is equalised, hence the reason they have the same HP, but obviously they are purposed completely and utterly for different purposes so the comparison is ridiculous.

An in-line engine kills the others for simplicity, weight and efficiency, that's why it's the most produced engine of all. The Suzuki Hyabusa 1300 weighs 100KG complete with it's integrated 5 speed gearbox, cut down versions are around 65KG for 175 hp stock (Google Hartley H2). All the 600cc bike engines are around 100hp for 80KG complete with gearbox, cut down versions as low as 55KG. Viking 170 = 1.4 hp per KG Lycoming 0320 = 1.35 hp per KG Rotax 912 = 1.35 hp per KG Viking 130 = 1.3 hp per KG Jabiru = 1.2 hp per KG ... so how are you coming to the conclusion it is heavy?

Sorry about lack of updates. As I mentioned my Wife's Father passed away a few weeks ago and now dealing with my Mum who has only weeks left. The life cycle just continues unabated, I accept it, but doesn't make it any easier, and Xmas certainly won't be the same this year. The project is a bit in limbo stuck between the old factory and the new one which I will hopefully move to within the next few weeks, it is happening, just on damn Chinese time. There are other background things going on for me as well over here. In the meantime I have been doing a lot of investigating and design work for a high wing. Fact is the Zenith, Savannah and Cub ilks are popular, so why fight it. I am structuring the basic Zenith and Savannah now into the computer and making changes suitable to my setup and currently available processes, as well as parts I already have. I have also made improvements that will end up getting back to the low wing as well. So it's all still moving forward, and now the high wing is a bit closer as well.

Undeniably true, and I am a campaigned for auto conversions, but the weight and simplicity of even an underperforming GA engine can not be denied. Auto engines are still a heavy and not so simple (water cooling) packaging problem. But they are getting smaller and lighter with every generation, the Honda/Viking 170HP unit is a true competitor, problem is we are still waiting for that true 80 to 100HP competitor to come along.

Me. I can kill this type of order in aluminium, the question is, is aluminium suitable?

Welcome Tim, hope you show us your build occasionally.

Great write up Peter, thank you.
