It comes back simply to the fact that you get what you pay for - and be very wary of Chinese claims and promises, when it come to electrical items. Virtually every single Chinese electrical item has some level of fraudulent claim attached to it.

I recently looked at some NiCd Sub-C batteries on AliExpress. The seller was claiming they were 2300 mAh. But one Russian purchaser provided photographic proof with his multimeter, that the batteries produced no more than 1900 mAh.

The seller just shrugged the review off - they don't care, it's all about lying bigger and better than any other seller, to ensure they get the sale.

Every single Chinese generator is over-rated, as to their true kVA output, under normal working conditions. 

I don't have much time for spiders, and I'm very wary of Huntsmans after one ran straight up my arm, as I pulled an old sign off a tree! The Huntsman was obviously living in the sign, and picked my arm as the quickest escape!

I can tell you, I never moved so fast in all my life - but it was still only half the speed of that Huntsman, they move like lightning!! I once had one run inside the car, and then disappear! - now that raised all my spider fears to a new level!

But the very worst spider fright I got, was picking up my flip-front oxy-acetylene goggles one day, then pulling them into position - only to see the outline of a massive Huntsman, right against my eye!!

I ripped those goggles off in about 0.0000000000001 of a second! - only to realise the poor old Huntsman had parked himself in the gap between the flip-front coloured lenses, and the clear lenses in the frame of the goggles!

So he wasn't actually against my eye, it just initially appeared that way! I think the part that unnerves me is those eight legs tickling my skin as they move at speed across my body! Their running speed is phenomenal, something like 5M/sec.

........extending the claim to cover every area where even the smallest remnants of any shells could be found. However the part of the claim that drew the biggest gasps was when Turbo lodged a claim over the most sacred of the White Mans land - the MCG.

Turbo noted in his claim that 40,000 years ago, the MCG was under water regularly, and part of the tidal flats of the so-called "Yarra River" (which as every young person knows today, has actually been known as Birrarung by the Wurendjeri people, for 41,000 years). 

As a result, the soil of the MCG contains more Wurendjeri oyster shell remnants than anywhere else - even including Woomera or Deloraine. As a result, included in Turbos claim, was that this ground, comprising millions of remnants of oyster shells, along with minute flakes of skin from foreskins, had to be excised from White Mans ownership and control, and returned to the Wurendjeri peoples, accompanied by a smoking ceremony that had to include......

You can substantially reduce stress points by avoiding sharp radiuses on the corners of the hole you cut - and the doubler is an excellent idea that not only holds the inspection plate flush and secure, it also adds strength to the sheet that has been cut.

There are reportedly three basic fears, which are primal - Death, Abandonment and Failure. But those fears can then be divided into multiple varieties of each primal fear.

I believe one of the most predominant fears today is a fear of strangers - and that fear gets worse, as people get older and more frail. I find a lot of old people are fearful of answering the door, in case they come under threat.

I believe this fear is largely driven by the media who concentrate on the reporting of violent attacks, murders and other human nastiness. The media make it appear your life is under constant threat from any stranger, which is not an accurate representation of real life, where less than 1% of the people you come into contact with, could possibly be a threat to you.

I have rarely encountered anyone who has a fear of flying, but it appears a sizeable number of people suffer from it. It's all about loss of personal control - many people have huge problems when control of what is going to happen to them, is taken away from them. 

As the old saying goes, "I live with Fear constantly - but sometimes she lets me go fishing".

The site below concentrates on people handing their primal fears over to a trust in God. This is the American Way, I believe a lot of people outside the U.S. are more pragmatic. However, when fears become overwhelming, many people look to blame a superior power, or rely on a superior power to try and lessen their burden.

The training level here is obviously pretty poor. What happened to the pilot monitoring? There was a double failure here, one pilot made a stupendous, inexplicable error, and the monitoring pilot also failed to pick it up.

Surely, with both props brought to feather, the power loss/airspeeed loss would be instantly noticeable? There was no monitoring going on, to lose both power and airspeed, with neither pilot noticing anything wrong.

........rort, as with everything that Turbo is involved in, and soon there were rumblings of discontent amongst the adherents of the Turbine Church of the True Believers in Archaeology (TCTBA for short), and the calls for more transparency as to where all the money was going, along with calls for external auditors to be appointed, plus calls for a new management board consisting of Deacons of Archaeology (DA's) to be appointed.

These rumblings and calls that were becoming louder every day, led Turbo to desperately try to pull out a distraction for the True Believers. He thought and thought, and then a great Revelation struck him! (no, not physically - being physically struck by a Revelation, is not a pleasant experience, I can tell you, from first hand experience). Turbo had suddenly understood that the reason the Church of Scientology was so successful, was because.......

...........Nostradamous  XV111 had not only previously visited numerous remote areas - he had left a numerous of strangely-worded cryptographs inscribed into stone tablets - some of which seemed to show images of lighter-than-air machines powered by mysterious means.

Turbo spotted these stone tablets, now residing in the Institute of Archaeology in the British Museum, when he visited the U.K. on one of his many business trips to drum up more finance for his new electric Drifter.

He immediately recognised the images, and set about decoding the cryptographs, which the British Museum archaeologists had so far failed to do.

But Turbo's brain works on a different level to the archaeologists, and he soon had all the information he needed from the writings on the stone tablets, to develop this new and amazing power source. Accordingly, he held a meeting to.........

The major thing is to design a cabin that doesn't crush (buckle in halves) upon impact in a hard landing. If you're going to dive into terra firma at 45° or steeper, then nothing is going to stop you getting killed.

But a cabin that doesn't fold up in a forced landing is a crucial factor in any new light aircraft design, and can be a big selling point.

.....abused everyone for not following his lead in electrifying aviation (avref). Very soon, the battery and electric motor builders were spying on bulls setup, to see what he had, that they didn't.

But the spy cameras only revealed a distilling setup, some rusty sheets of CGI, and bull running around furtively, holding a handful of loose wires.

The battery and motor spies decided that bull was taking extra precautions with security, and trying to throw them off the trail of his major electrification developments.

The truth was, bull was simply perfecting his moonshine distilling, and trying to electrify as much of the liquid pumping as possible - but the wiring was causing him hassles, as he'd failed his electrical course at night school, and he was simply trying a blue wire instead of a black wire, or a green wire instead of a red wire - but none of the changes had produced the results he wanted, yet - until the day he grabbed another handful of wires, and found them connected to............

I always wondered why light aircraft manufacturers didn't come up with a "two halves fuselage shell" design, as this was the feature that made the Mosquito a winner, when it came to ease of construction and low cost of construction.

......live off the grid in the deep forest in Tasmania - as bull does. However, bull is steadily developing his plans for an electric aircraft, powered by a new battery design, which is going to use only local Tasmanian materials in its manufacture - and of course, it will be charged by a multitude of solar panels, all set up to change their direction at a moments notice, the instant the sun is sighted in Tasmania (which is not often, but which event is celebrated when it happens).

Accordingly, bull has been researching the electrical-transfer properties of Tassie Tiger dung, rotten apple pulp (of which Tasmania has plenty), and even Cat farm urine (ever since he discovered a Turbine Industries Cat farm hidden in the forest), which produces so much cat urine, it's posing a disposal problem for TI. 

After making local enquiries as to where he could contact the manager of the TI Cat farm (just approaching the place directly wasn't in his plans, as the signs warning of trespassers being shot and then hung, gave him some idea that a direct approach wasn't a practical idea), bull gathered that he had to wait until the manager contacted him, and then.........

......those countries where ruthless dictators still mostly ruled. However, in those countries, once the dictator was paid off, it was perfectly acceptable for the KFS to proceed unimpeded, as most of the populations of those countries wouldn't have known the difference between a Kiwifruit, a Grapefruit, or a Pineapple, even if one was shoved........

.....do a cavity search for weapons and drugs - because these MIB were from the TSA, and you don't want to get on the wrong side of a TSA operative, they make CASA operatives look like pussycats.

Speaking of pussycats, Turbo's mind was whirling again as he tried to figure out how to join the lines between his Cat Farms and the huge surplus of pineapples. There had to be a way to utilise all that surplus pineapple juice, and feeding it to the cats was looking like a good idea.

However, the last time Turbo tried feeding a cat some pineapple juice, he got scratched from face to feet, so it was going to really take some innovative thinking to.......

......canned pineapple juicer, which Turbo had recently patented. Turbo was on a roll with his new design of juicer, which he invented the minute he heard about all the pineapple crop fruiting simultaneously, leading to a massive pineapple glut.

He knew that canned pineapple juice was a great product, could be stored for a long period of time, was a popular addition to many cocktails, and the market could be expanded substantially with a bit of promotion.

Plus, there was the profitability factor, one factor that always led Turbo into new ventures. The profits in pineapplejuicing were huge (particularly when Turbo offered to take away all the surplus pineapples for free), so all Turbo needed to concentrate on, was..........

I think most purchasers wouldn't be impressed with those battery-powered pumps - simply because their flow output is painful.

The quoted flow rate is with the outlet level with the top of the fuel in the container. As soon as you raise the end of the hose, the flow rate falls off to a trickle, and it takes many minutes to empty a 20L container.

What do you reckon is behind this very coy information from Continental? A batch of dodgy crankshafts?

Maybe their new, cute, all-automatic, random QC inspection machine, went out of spec?

They've been reading this thread!

The pricing is certainly very coy, and no doubt this is related to the complexity of installation, and the highly variable costs according to each make and model of aircraft.

The figures I have seen bandied around, are "US$10K to US$40K". Obviously, the US$10K is the price of the bare bones Stec 55. The US$40K would be for a complex installation, all-up.

With good used units being offered at US$3500 on eBay, I would opine the figures quoted are reasonably accurate.

(sorry, Men ..... I was back in the J again......................)

Remember you're dealing with the greatest bureaucracy in Australia, that has virtually no accountability, and which cares little about costs incurred by the people they control, at their leisure.

I'm guessing they'll be re-writing the Coulson pilot manuals right about now, as regards low-level flight and at speeds close to the stall. I think Nev is spot-on, the Coulson pilots seem to be too keen to get down close to the fire, and they are probably getting a surprise at the level of sink from the swept wing at low speeds, and in hot conditions. The B737's whole design is centred around moving a pile of pax at 0.78 mach, that's where they spend 95% of their time.

When you redesign the aircraft to carry a huge tank of compact weight retardant in one small area of the fuselage, and then attempt to operate at as slow a speed as possible, you're going against every single original design feature of the B737.

The other angle too, is the level of power loss from a jet engine in hot conditions. That ISA + 20°C can apparently cause about a 10% reduction in power, and coupled with the loss of lift (1% loss for every 3°C above ISA is the figure I saw), it all adds up.

At $9, that el-cheapo plastic pump will more than likely fall apart before you even get the tank full - that's if the "generous" clearances inside the pump mechanism actually pump any amount of petrol.

This a typical "breakaway" ridge (photo below) within the Fitzgerald National Park that the B737 is likely to have clipped. Usually only about 60 to 100 feet high, rarely reaching 120 feet.

I was surprised to find the weather records show that it was an unusually hot day for this area. The nearest weather recording station is at Jacup, just outside the Park, to the NW.

Jacup recorded 36.8° maximum that day, and it was still 35.8°C at 3:00PM, just over an hour before the crash happened.

There was a big pool of hot air over the Park both on Sunday 5th and Monday 6th, drawn in from the central N of W.A., via a fairly strong hot Northerly wind, that was averaging 28kmh (15kts) and with gusts to 46kmh (25kts), just after 9.00AM.

By 3.00PM, the tip of a cold front from the South had swept through the Park, and the wind direction had changed to a Westerly at 30kmh (16kts).

http://www.bom.gov.au/climate/dwo/IDCJDW6058.latest.shtml

So I don't think vicious wind gusts, or wind rotor effect over the ridge, would have had any impact on the aircraft, as regards crash conditions.

I would expect the relatively high ambient temperature (exacerbated by flying close to the hot ground) might have played a part.

Perhaps clipping the mallee trees on the ridgeline was caused by a misjudgement of available lift in the high ambient temperature conditions, at near stall speed - and the resultant drag of the vegetation on the fuselage was just enough to slow the 737 down, and make her pancake onto the valley floor below.

As I understand it, spool up lag with a jet engine can be several seconds, and any extra thrust required, when it's obvious you need it, comes too late, at very low level.
