Marty, it looks like they use a sort of "wobble drive" universal-joint setup in the driveshaft. This system simply tilts the rotors. They claim they're aiming for maximum simplicity and the minimum number of parts/components to stay aloft safely. Their cruise speed is a reputed 130kmh, and probably the interesting part is they are claiming "automatic flight", rather than "autonomous flight". They say that it will be many years before totally autonomous flight is possible and achievable, thus they're concentrating on automatic flight, using fixed flight paths, and pre-designated take-off and landing areas. This seems to indicate remote control of these e-copters. It looks like they're aiming at inner-city air-taxi type operations and cargo deliveries. https://www.flynow-aviation.com/

Mat's small number of posts on here indicated a reasonably good understanding about the limitations involved in flying light aircraft, but it appears he succumbed to the age-old problem of poor pilot decision-making, in taking off into inclement weather, obviously feeling a pressing need to carry out his flight. I would opine we've all seen reports of reportedly good pilots with modest levels of experience, making poor decisions to take off, when they should've stayed grounded. I'm not so sure that another 15 or 20 hrs of pilot training would have benefited Mat, unless that training really hammered decision-making, relating to whether a flight would be able to be safely carried out or not. The problem centres around the fact that everyone is different when it comes to decision-making, and some of us are more impulsive than others. https://www.recreationalflying.com/profile/11812-mat-farrell/content/

That screenshot looks like he's relieving himself, before he even gets in! What a clever idea!!

The crash report is only preliminary, the NTSB did not travel to the scene of the crash, and all the "evidence" presented is from the pilots and witnesses statements. https://data.ntsb.gov/carol-repgen/api/Aviation/ReportMain/GenerateNewestReport/195385/pdf

The tubing will likely be precision seamless drawn tubing, made from aviation grade alloy, heat treated and tempered to a British or American Standard. The precision finish is required to ensure minimal unevenness in wall thickness. No aluminium agricultural pipe for carrying water would have any degree of strength, it is seamed (a weakness), and it would have a large variation in wall thickness over each length. However, you can purchase Unipipe, which is produced in a range of aluminium alloys, some of which are designed for high pressure piping, and which may have adequate strength. The "T" reference in the aluminium grades refers to the heat treatment, with T6 being the strongest and toughest aluminium grade - but it is also the grade with the lowest level of elongation. Elongation is the figure that shows just how much a metal stretches before it fractures. Lower strength metals will generally have higher elongation rates than high strength metals, but this is not always 100% the case. Good corrosion resistance is also a highly desirable characteristic of any aluminium material used in an aircraft. Aircraft Materials WWW.AIRCRAFTMATERIALS.COM Aluminium 6060 Data Sheet - BlueScope Distribution WWW.BLUESCOPEDISTRIBUTION.COM.AU 6060 is a medium strength heat treatable alloy with good corrosion resistance, weldability and responsiveness to anodising.

Possibly one too many dog leg-cocks on tree, and tree finally gave up? Dog looks pleased, must be a reason for that.

Well, it does get to play a part in engine cooling if it returns to the cooling system.

You should never lose coolant overboard at any time, under normal operation. Coolant lost is cooling ability reduced.

The wreckage of the Caravan has been found and there are no survivors, the aircraft crashed onto sea ice and was totally destroyed. Coast Guard Lt. Cmdr. Benjamin McIntyre-Coble is reported as saying, "(the aircraft was involved in) some kind of event which caused them to experience a rapid loss in elevation, and a rapid loss in speed. What that event is, I can't speculate to." Ten Dead In Alaska Caravan Crash WWW.AVWEB.COM Plane went down in fog on sea about 12 miles offshore.

The sheer idiocy is in the allowing of intersecting air traffic at low level, with only 100 feet clearance, where height measurement can only be done reliably by very precise instruments. FFS, the NTSB is still struggling with altitude accuracy of the Blackhawk from its FDR, which wasn't even time-stamped. They're talking about trying to define to more accuracy, a 50 foot altitude variation at 300 feet! Even the ATC screens only report 100' variations. And why did the Blackhawk pilot request "visual separation" when ATC were in a far better position to advise track and altitude? The U.S. military has to wear a lot of blame for this crash, with procedures that act as if they're the only ones in the sky. NTSB Delayed In Altitude Verification Of Collision Aircraft WWW.AVWEB.COM Blackhawk’s FDR data was missing time stamps.

.....the Jaguar badges won't be regularly pilfered by the multitude of Indian poverty-stricken Indian orphans, who have been known to even nick engines from running Drifters and Thrusters - thus leading to great mystification amongst Drifter and Thruster pilots, as to why zero thrust was available, despite full throttle being applied. One of these notorious orphans, a quick-witted youngster named Paramjit Turbonakshi, was the primary suspect involved in a large blackmarket of near-new Drifter and Thruster engines regularly available cheaply, in many States on the Sub-Continent. The Indian Police were regularly outsmarted by Paramjit Turbonakshi, as it appeared he always had prior knowledge of policing actions that were planned. Finally, a trap was devised, whereby a police stooge by the name of Onkar Cappiranjit - who had formerly been a good friend of Paramjit Turbonakshi, before they had a falling-out over an entire shipload of blackmarket gin, that disappeared whilst supposedly under Onkar Cappiranjit's supervision - was to act as a............

Do you understand there will also have to be a comprehensive tree danger audit, within the complete aerodrome boundaries? Every standing tree will require a full assessment, as to its particular danger to aviation and aviators! Just imagine, you could've easily been the first "falling timber" aerodrome fatality. The aerodrome rules will need to be re-written!

.....goad CASA inspectors (and Fisheries Inspectors) any time they wanted to take a peek at bull's equipment. Now, when we say "equipment"; people with low-level thoughts (such as Cappy) would be drooling at the thought of acquiring a photo of a CASA inspector, inspecting bulls "equipment" - but the truth is, when the word "equipment" is used in this context, it doesn't refer to any of bulls wedding tackle, it refers to items he's using during flying or fishing, which have a level of safety requirements attached to them. As bull is known to regularly ignore a lot of safety regulations and other...........

The engraved plastic strips glued to the instrument panel would be my choice. The plastic strips are multi-layer strips of plastic and the engraving produces a very professional finish. Dymo tape falls off with high temperatures.

I think that statements a bit of a cheap shot - without providing any evidence - at a lot of people who do a lot of hard work to try and define causes behind crashes. There may be some studies, initiated by companies with a vested interest, to get a desired study outcome, but the studies by the universities are generally even-handed.

It's around 12% for car and truck drivers, surprisingly. The University of Adelaide did a study on it in 2008. For pilots, quite likely a lot less, but possibly more than you might expect, too. After a serious aviation crash, often with accompanying fire, it can be difficult to determine precisely whether a medical event precipitated the crash. For older pilots (over 65), the potential of a medical episode causing a crash would be greatly increased.

I can recall a a fatal with a microlight at Beverley, W.A. in the late 1970's/early 1980's. He took off with fuel tank cock turned off. Got up to about 100-150 feet, and came straight back down again. The irony of the incident was, the bloke was a senior air crash investigator with BAS, and he must have seen and investigated dozens of air disasters caused by simple human errors, and a lack of disciplined checklists. Even the best of the best, and some of the most highly respected aviators, have terminated their lives (and others) with incredibly simple errors, related to forgetfulness.

Well, the willy-willies they measured might have only travelled at those low speeds, but I can tell about some personally viewed experiences of mini-tornadoes in W.A., that would indicate wind speeds in excess of 200kmh. In July 1975, at my minesite at Higginsville W.A., I endured a frightening night of howling winds from a major storm that travelled through the Southern Goldfields and S.W. W.A. I was sheltering in a 3-room former railway fettlers hut, a very sturdily built timber building, that was built in 1907, when over-building for strength was the order of the day. I'd transported 4 of these buildings to the mine in 1972, from the nearby Pioneer siding, when the narrow gauge line was upgraded to standard gauge in 1971. I would estimate the consistent winds that night, of around 70-90kmh, with gusts around 100-110kmh. In the morning, I drove S into Norseman, down the Coolgardie-Esperance Rd, and about 10kms S of my mine, a mini-tornado had left a trail of destruction through the native vegetation on the Eastern side of the highway. Now, the vegetation in that area is hefty stuff, big Salmon Gums, decent-size Gimlet trees, and Goldfields Blackbutt trees, interspersed with lighter scrubby trees and bushes. But there was a strip of country there, that looked like someone had dragged a clearing chain between two bulldozers along it. Big Salmon Gums, a metre wide at the base, had been screwed off about 1.5-2M high, leaving shattered stumps. There wasn't a single tree left intact over a length of probably 700-800 metres, and about 100 metres wide. It was total and utter devastation, and it was caused by intense cyclonic wind, and nothing else. I wouldn't have liked to have been in a building in that mini-tornado's path. I've seen the results, in the wheatbelt, of multiple numbers of farm sheds that were destroyed by mini-tornadoes embedded in storms. Some of them were sturdily built from RSJ (I-beam or Universal Beam, or Universal Column, as they're called today), with structural steel trusses. The tornado-like winds just blew them apart. In one case, the mini-tornado picked out a single shed in amongst a group of sheds and a house, and destroyed that single shed, and nothing else. It was like the mini-tornado had simply fallen out of the sky onto that single shed. I have great respect for what concentrated strong winds can do, especially when they're in storms embedded in strong cold fronts, or in thunderstorms.

In W.A., the structural engineer certifies the design as safe and meeting structural standards, so I'd guess the buck stops with him. As to wind speeds, that would have to be a curly one when it comes to a stoush over a collapsed shed. Willy-willies/mini-tornadoes can develop high wind speeds over a small area and a short distance. I can recall my father telling me about seeing a windmill tower screwed up so tightly by a willy-willy, the tower ended up looking like a length of steel wire rope. You'd need an anemometer on the site to be able to get the exact wind speed of any willy-willy.
