The turf equipment tweels are rated for a maximum speed of 25mph (40kmh), and the tweels for ATV/UTV's are rated for a maximum speed of 50mph (80kmh). No model of tweel is approved for highway use yet. There's a considerable increase in rolling resistance with a tweel, as compared to a pneumatic tyre. So, I'd have to opine that tweels are unsuitable for any aircraft. The fact that the manufacturer hasn't sought to produce a tweel specifically for aircraft, tells me that the tweel is limited to off-road, low-speed vehicles only.

Yes, the forum is based in and run from Australia, but users from all countries come here, and are welcome if they provide content that is interesting, informative, and which adds to our combined aviation and engineering knowledge. I wish you well with your product, it looks good, and is likely to be acceptable in many countries. I just felt the need to address the issues associated with private (i.e. non-commercial) fuel transport within Australia and its territories, and point out the risks associated with highly combustible fuel transport, which risks are regarded as serious ones by the relevant authorities here. Fuel transport containers must meet the relevant Australian/New Zealand Standard, which is - "AS/NZ 2906: Fuel containers – portable – plastic and metal". Below is a link to one of the Australian States, Workplace Health and Safety (equivalent to OSHA) guidance booklets, for the storage and transport of flammable and combustible liquids. https://www.worksafe.qld.gov.au/__data/assets/pdf_file/0024/22866/guide-for-flammable-and-combustible-liquids.pdf All of our legislation and regulations regarding fuel transport and storage, are centred around risk reduction and education of end-users, to minimise accidents and disasters.

You might want to get a handle on the fact that Australia uses 240V power, not 110V, it has different power plugs and wiring as compared to the U.S. - and all containers for carrying fuel in vehicles in Australia must be approved by Govt authority, under the Transport of Dangerous Goods Act - with each State having slightly different regulations, as regards fuel transport in vehicles. In addition, all containers carrying Hazardous or Dangerous goods must be labelled under the GHS (Globally Harmonised System) labelling regulations. Most Western countries (including the U.S. and Australia) are party to the GHS labelling system. This system clearly identifies the hazardous substance with pictograms on the containers or vessels and also provides readily provides MSDS information for first responders to fires and crashes. 250 litres is the maximum allowable volume to be carried in private vehicles in Australia - above that amount, you need to have a commercial Dangerous Goods transport permit, and your vehicle must carry standardised U.N.-markings - the Dangerous Goods diamond-shaped warning plates, front and rear. Documentation for the DG load must also be carried in the vehicle, relating to the supplier and carrier, and responsible persons contact details. This type of DG load is referred to as a "placarded load". 50 U.S. gallons is approximately 190 litres. Note that the 250 litre transport limit for vehicles in Australia, includes the fuel in your vehicle fuel tank. A fuel transport container on wheels may not get approval to transport in a vehicle in Australia, as fuel transport containers are required to "be properly secured" in a vehicle. Adding substantial tie-down points to your Fuel Mule would be advisable, to ensure it received official transport approval in Australia. There is an important distinction between petrol fuels (avgas and gasoline) and diesel-based fuels in Australia. All fuels with a flashpoint below 60°C are classed as "Flammable liquids", but fuels based on petrol are classed as Combustible liquids, because their flashpoint is around -43°C, and they will ignite easily from a single spark, at well below room temperature, thanks to the large volume of volatile fumes these fuels produce. Diesel or kerosene-based fuels do not pose such a severe flammability danger as petrol-based fuels, because they do not produce the same level of volatile fumes as petrol-based fuels. If you own a boat, you are no doubt well aware of the dangers of refuelling with volatile fuels, and the need to avoid containment of the fumes produced. I have seen an entire major fuel storage depot burn to the ground, simply because a customer refuelling his car and caravan (trailer home) out front of the depot (via a depot fuel bowser), spilled some petrol, due to overfilling his (petrol) fuel tank. The petrol fumes wafted into his caravan, where he'd left his LPG fridge burning. The petrol fumes ignited via the gas burner flame, the caravan went up in flames, the car joined it, then the fuel depot caught fire, too! It ended up a multi-million dollar fire, and it wasn't even in a built-up urban area, it was in a small country town, where the depot was located in an isolated industrial area of town. A strong, steady wind aided the fire to take hold rapidly. There's a general official attitude discouraging the transport of any more than about 50 litres of petrol-based fuels in vehicles, in Australia. This is because of the severe level of danger involved in the case of a vehicle crash, where a vehicle is carrying more than about 50 litres of petrol-based fuels, in portable containers (or container). Fuel tanks built into vehicles have a major level of protection built into their design, such as their location, plus protective shields around the tank. This is not the case with volatile fuels being carried in bulk containers in vehicles. Finally, service stations (gas stations) in Australia will generally not allow the filling of portable fuel transport containers in vehicles, due to static ignition fire potential. All portable fuel-carrying containers must be removed from the vehicle and placed on the ground for filling, and the container size being filled is not allowed to be larger than 25 litres.

The primary factor involved, is whether any medication affects brain function, and in what manner. There's a substantial number of medications that affect your driving/operating/piloting skills - and this information is readily available from the drug manufacturers, and the medical profession. However, just in my personal opinion, I believe a lot of drug manufacturers, and even medical professionals often downplay the full effect of medications. I know I've taken medications that adversely affected my skills and decision-making, and I wasn't advised fully on all the side-effects. I would hazard a guess this is because everyone is affected a little differently by various medications. From what little I've read about ADHD medications, they're touted as a gift from God, with amazing results, and little side effects. I'd have a more reserved opinion on that angle, purely because of the power of drug manufacturers, and how they can influence even medical professionals. I was under the impression that the main drugs used to treat ADHD are all from the amphetamine family. These drugs are commonly nicknamed "speed" drugs, simply because they stimulate brain function. In the case of ADHD, it appears the amphetamine drugs operate on brain function in a highly beneficial manner - unlike the illegal methamphetamine drugs. Naturally, the legal drugs are produced to a medical standard with proper QC, unlike the illegal ones. However, the bottom line with amphetamines is, they are addictive - and the other question also remains, with regard to someone needing to take a legal prescription of amphetamine, is - what happens when they're piloting, and they forget to take their medication? I believe the situation as regards someone piloting with a need to medicate, to function effectively, is a question that needs to be addressed on a simple case-by-case basis, with extensive medical professional input, and not a "one case fits all" scenario. Just my .02c worth.

The very first Douglas DST, and the first Douglas aircraft with sleeper berths. But it wasn't the first aircraft with sleeper berths, that claim to fame goes to the Curtiss Condor (in 1932).

I don't think there's any sniggering needed if someone has studied up and learnt to fly, and has passed the tests to acquire a licence, it's something to be proud of, and I for one would not be sniggering at anyone wearing a set of wings that has been earned, I'd respect their effort and achievement. But if someone was wearing a set of wings that hasn't been earned, and they were just trying to impress - well, there's a name for that character deficiency.

The predictable result of many years of a highly complacent attitude, and poor procedures developing, without anyone picking up on his bad habits increasing.

.....only a little earlier than the Turbine Industries Great Defence Procurement scandal, whereby used missiles from the various Middle East conflicts were gathered up and reconditioned, and sold to AUKUS as new missiles. Turbo was actually sighted at the recent Land Forces International Land Defence Expo, held at the Melbourne Convention Centre, spruiking the huge advantages in purchasing his low-cost, fully recycled missiles, which came with a slew of Green credentials. Turbo became quite animated when he went into high levels of boasting about his companys missiles features. "They're fully tested, as shown by the fact they've been successfully used, which indicates they work!" he said. "I guess many of you would know, that missiles that fail to go off when they reach their target, are a major problem! We've solved that problem by re-using missiles that were proven to go off!" Despite the regular murmurs of a suspected scandal coming from various other Defence suppliers, the scandal wasn't actually fully uncovered until the missiles were provided to the Ukrainians, whereby it was found, that......

Hi Dave - The meters are new, the discolouration is because there's a protective plastic strip stuck to the face of the meter. Where are you located? I'll give you a call tomorrow, because it's a little late in the evening right now. Cheers, Ron.

How did they ever get a fake window through the certification process?? Surely, it must be an unauthorised modification?

The road toll dropped sharply during the pandemic, due to restrictions on peoples movement. A substantially reduced level of driving and moving around by road, resulted in an abnormally low road toll. Somewhat surprisingly, and in a reinforcement of official policy - although there were a lesser number of crashes, the level of crashes resulting in substantial major injuries, increased. This has been attributed to drivers speeding more, because there was less traffic on the roads! Higher impact speeds in crashes = increased level of major injuries.

.....uncover more of Cappys failings and cover-ups, to make Turbo's transgressions and elaborate fabrications look a lot less deceiving. He railed against Cappy and his pointing out of the unrifled bullet; "How many people know about the time you took off (long-overdue avref) with the logbook sitting on the wing, and you had to land again and try to find it, without anyone seeing you?" Cappy went pale. He wasn't aware that anyone, let alone Turbo, had known about his little mistake. Anyone can make mistakes, but letting Turbo find out about them, was.............

One has to agree that Skippys belief in the concentration on speeding offences is the wrong and regular response to an increasing road toll, and amounts to a failure - simply because the road toll has increased sharply since 2020. The 2023 road toll was the worst for years, and 2024 is well on the way to being the worst road toll in decades. Speeding is only one part of the equation, and what the authorities conveniently ignore is that speed alone doesn't kill - it's speed coupled with driving inexperience, a lack of competent driving skills, negligence, and just plain carelessness. I would opine the last factor is a big factor in many smashes, the number of vehicles that run off perfectly good roads into roadside trees, indicates major carelessness and negligence in driving attitudes.

.......more strident and insistent, as regards the truth behind the 7.62mm bullet with no rifling marks! Turbo stayed silent as the furore increased, and more and more stories came out, about how he'd found a stray un-expended 7.62 mm bullet near the firing range at Kapooka, when he'd been up visiting Cappy, and he'd carefully removed the bullet and fabricated the whole story about his limp, and the Pashtun bullet reportedly extracted from his hip. Of course, Cappy drove the furore by feeding the journos titbits about Turbo's constant character flaws, and the fantasy land he lives in. "We all know AK-47's and M60's weren't around in the 1880's!" exclaimed Cappy - "so who's going to end up with egg on their face?" "You are!", retorted Turbo, when he finally broke his silence. "Your talk about the 1880's Khyber Pass stoush, was the story of my grandfather! I was there again in the Russian invasion of Afghanistan, and I taught the Russians all they know about fighting tactics!" "So ... that'd be the reason they lost the war with the Afghans?", sneered Cappy. Turbo blanched. This was one insult too much, and it'd be the last time he gave Cappy any bottles of gin for his birthday, because he'd finally.........

There's no argument that both ends of the age spectrum show statistics that indicate an increased level of crashes by both groups. In the young people, the reasons are impulsiveness, risk-taking, lack of experience, and inadequate control skills (related to the foregoing). In older drivers, the reasons are age-related cognitive decline, slower reflexes, age-related health conditions, and (the very worst part) - a substantial long-term decline in driving skills, caused by bad driving habits that are not addressed. Things such as driving through stop signs on a regular basis, rather than stopping, and looking as required. Failure to keep up a consistent level of alertness, as in looking for vehicles, in a regular pattern, when pulling out into conflicting traffic. How many of you have had an aged driver pull out directly in front of you, without looking, or with a casual glance that does not register your vehicle is there? I get it regularly, but I make allowance for older drivers. Then I get someone in their 40's or 50's who does the exact same thing! - showing a decline in driving skills and habits, that is already creeping in, and not being addressed. I nearly cleaned up a medical professional in his 50's in his big new Mercedes on Thursday, when he pulled out straight in front of me, without even a glance in my direction! He made things even worse by pulling into my lane, without indicating or looking (because the kerbside lane was full of parked cars) - leaving me nowhere to go, but up onto the centre median strip under extremely heavy braking! Yes, I should've been going slower, and allowing for him doing something stupid - but he sprang straight out of the side street, on my left, from in front of a truck turning left, so I couldn't see him until it was far too late. This decline in keeping up strict driving habits starts after about 15 or 20 years of driving, and continues to get worse, unless it's addressed with corrective instruction, and effort on the part of the driver. We've all seen how taxi-drivers skills decline through bad habits, and long years behind the wheel, and you don't have to have aged taxi drivers, to encounter it.

It looks awfully like the designers of the GAF Boomerang saw this prototype, and got a lot of ideas from it!
