Actually, although the air circulation pattern is a fact, I'm pretty sure that the facts were used by anti-airport campaigners to push a completely different agenda. I found that material years ago. In fact, if you look at the design of the website you will see that it is very early 21st Century DIY style.

Not a downer. That air circulation pattern is natural. It's only been with the growth of Sydney and suburbs to the south of the Parramatta River that nasty stuff has been brought into the northern part of the Wollondilly Shire. The residential development in the northeastern corner of the Camden Shire has introduced more pollution, mainly from private vehicles since there is inadequate public transport. That link I posted was to a site that was discussing the effects on air pollution possibly arising when Nancy Bird Walton Airport becomes operational.

The biggest problem from airborne material at The Oaks is the pollution from the areas of Sydney to the northeast of the airport. There is a natural air circulation pattern that brings pollutants to The Oaks. Look at this: Air Pollution in Sydney Basin WWW.CONDELLPARK.COM Sydney Basin Pollution Sources and Health Effects

I think that when discussing the weather of a particular locality, it is best the heed the words of those who actually live (lived) there. Skippy lives within 5 kms of The Oaks, and I lived and worked for thirty years within 15 kms of it. Unless there is a Low Pressure cell in the Tasman Sea south of Wollongong, the prevailing winds are from the southwest in the morning, with the nor'easter arriving about 3:00 pm. If there are thunderstorms, they tend to split into two before reaching The Oaks. One side drifts down the Nepean River to Penrith, and the other down the Georges River to Bankstown. The storms that you hear of doing a lot of damage are the ones that go down the Nepean and link up with the ones coming over from Katoomba. As a result, that southwestern rim of the Sydney Basin is pretty much in a rain shadow. The rain coming from a more easterly direction off the coast usually stops at the Georges River, roughly in a line from Bankstown Airport to Wedderburn. So it doesn't get to The Oaks. Solar radiation is going to be a problem anywhere.

I'll go look.

I just heard the bushfire weather prediction for this coming winter. It's gunna be dry, so I wouldn't be worrying about WerriBerri Creek bursting its banks, A lot of the aircraft parked at The Oaks simply have a weatherproof cover over them. Methinks Chris is mistaken about the severity of Sydney Basin winters. For a Swiss, the weather would be considered balmy.

Spacey, You haven't told us what the rule is. I would have thought that high wing loading would be the killer. Is 5.3 kg/sq m a high wing loading?

Ah! If wishes were wing'ed horses, buggers like me would fly. Lexicographer's Alert. Spacey wrote, that innocuous " wing loading rule Spacey, you've chosen the wrong word for to describe that rule as it applies to the Hummel Bird. Innocuous means "not harmful or offensive". The word you really wanted was iniquitous which means "grossly unfair and morally wrong".

What exactly are the figures used in that rule? According to the published specs, for the Hummel Bird's 18 ft (5.5 m) wingspan with wing area of 57.2 sq ft ( and Gross weight of 550 lbs (250 kg), it has a wing loading of 9.6 lbs/sq ft (5.3 kg/sq m)

What's the price with a comma as a separator?

My go to fastener supplier for non-aviation spec stuff is www.bolt.com.au at Smeaton Grange, which is near Camden NSW They list an M22 x.15 locknut for $7.80 Part No BLNMF22x1.5 There is a store in Dandenong. Store Locations WWW.BOLT.COM.AU Find your nearest local Bolts & Industrial Store.

I was watching some recent video reports of aircraft trade shows in England (Popham ?). I was amazed at the number of different manufacturers and the equipment levels in even the basic trainers - and the prices. The cheapest I heard was 80K Euros for a trainer. I was also interested to hear that diesel engines, running on Avjet were commonly used, as was a BMW motorcycle conversion. The aircraft using them seem to be coming from the Eastern European countries. Rotax, of course was well represented, and there was reference to Lycoming, but not Continental. Also often commented on was the 600 kg approval. What does tha mean in terms of the lighter end of the market?

WSell, It's your money.

I honestly think that it is too much aircraft to be useful to the average pilot who flies for recreation.

Ha! Ha! Ha! That's what you get for going to the Dark Side and using metrics. The size of a bolt is determined by what loads it has to deal with. The size and type of washers, and bolts follow from that. The designers have calculated those loads and specified size and material. An M22 size is a poofteenth smaller than an Imperial 7/8. If the designers had specified Imperial sizes, you could have obtained what you wanted with great ease.

Dream on, you lot. The Emu will be the one in the Cirrus.

January does bring a risk of hail, but at The Oaks it is not usually the sort that will cause great damage. It's usually pea-sized. Putting some soft material under a waterproof sheet would act as a buffer if there was a hail storm. Ask Skippy for better local knowledge. My comments are based on living and working in the area for thirty years. I've never has a car damaged by hail in that time. Also The Oaks is on the lee side slope of the direction the worst of the storm weather comes from. The Oaks is also a handy place to operate from, especially in the future when the uncontrolled airspace over the Sydney Basin will become reduced due to the opening of Nancy Bird Walton Airport in the Basin's far west. Public transport is not really an option. There is a bus service, but intermittent during the day. Route 40 takes you to Camden for a transfer to a bus to Campbelltown where you can join the metropolitan rail system. Route 40 - Camden to Belimbla Park - Busabout Sydney WWW.BUSABOUT.COM.AU Mark as a favourite route Using Camden involves ongoing costs. That latest I could find were for 2021. $15.60/1000kg MTOW per movement. $2.60/1000kg MTOW per day, or part thereof. Movement. An aircraft departing the airport via taxiways, or an aircraft landing when it is the only movement detected in a calendar day. I don't know what it costs you go doing a session of circuits and bumps.

Just something to be aware of, but more for apprentice AMEs.

Your cheapest way out is to put it on The Oaks. Skippy will tell you if there are landing and parking fees ( I don't think so) At Camden you'll get hit with both, even if you leave it outdoors. HA, if you like short field landings and takeoffs, Skippy will put it in his shed for a few cartons of beer.

Am I correct here: Chrome rings + chromed cylinders = a big No! No!

If you are going to merge the two, I reckon you ought to put it in its own forum called "The Old Farts Corner". We use it just like that corner in the pub or club where a particular group of blokes gather and woe betide anyone not in the group who tries to sit there.

I called Redgrave's. Finding one of these coils is like finding a hen's tooth in a pile of rocking horse poo. But they used to have one. I have it now!!! Look out Central NSW! OME will be terrorizing the highways and byways by next weekend. Well. Not so much terrorizing. You can't frighten many at 80 Kph.

Can't use a single output coil because the system is wasted spark so it has to have two outputs. I had a look at Redgrave's shitty website which is only good for getting a phone number. Geez I hate DIY websites.

My point exactly.

Maybe someone in Melbourne could get them for you and send them. About the cheapest way would be in a CD box and cost under $10 for postage. I need a coil for my bike from the USA. I expect to pay more for postage than the cost of the coil. ($AU145)
