Trucks in Australia are different to what you see elsewhere. Never saw a bullbar in Canada, but lots of triple-axle drives- presumably for icy roads. In southern England I’ve seen lots of single-axle drives, with a second axle of single wheels sometimes sharing the weight, sometimes retracted. In London a few prime movers with such short wheelbase the axle just in front of the drive axle has steerable wheels.

Another aspect is engines overheating while takeoffs are delayed- a big issue where small batches of planes are marshalled to backtrack before TO. When it’s happened to me, all I needed was enough space to pull out of the line for a cool-off period.

Easily done. Tool weight lots, cost sqillions to boost into orbit. Last week I flew half way round the globe with my new wheelchair on board. Yesterday I walked miles to find a shop selling basic tools to re-tighten it’s connectors.

Get ready for the media frenzy against allowing fast taxi runs of a national treasure in such a small space.

So true Nev. Like the stupid cities built on dredged-up sand along the Persian Gulf, they are only a poofteenth above rising seas. Largely inhabited by trump loving climate change deniers...to be indundated and abandoned during this century . Poetic.

Another factor I hadn’t considered is that direct-drive props, like Jabs, would cop much more conducted heat thru the crankshaft than via a gearbox.

Many of us in the land of long weekend might get time off to do this, but I suspect that inflexible work contracts hinder many of our American counterparts.

Looks like the designers were faced with an oversupply of analogue instruments. Like the Bristol Two Litre, a sleek aluminium car produced after the war; it had a plethora of gauges right across the whole dash.

How often have I spoken to people keen to invest in their new venture or business expansion. The common theme is local government finding never-ending impediments to put in their way. Any government fair dinkum about supporting economic growth should appoint a single person to facilitate, guide and advise anyone willing to invest...and hold them responsible for the plurry delays!

In some parts of Europe the pubs are supplied via pipelines from breweries. If they can install beer pipelines across historic cities, why can’t we install fuel pipelines before it gets congested? Clever country.

Unfortunately this hasn’t proven to be true: most diesels seem to be adapted from cars, for which application their best output is when spinning a bit faster than the ideal prop revs. This means to save the weight of a gearbox you never use all power available-unless you prop is doing 3,500+ rpm. Noisy. Or maybe they need smaller diameter aircrews with big paddle blades?

…who had imigrated from Germany. A few hundred were built in Australia, but thousands were mass produced in America. At war’s end, acres of shiny new Mustangs were bulldozed into piles for scrap.

Good to hear you are safe, Meglin. We in Australia and around the world are impressed that your country can carry on manufacturing and exporting under war conditions. Just a suggestion: you and Bilguun seem to have quite a bit in common besides interest in aeroplanes. Many of his countrymen in Mongolia would have a better grasp of Russian than English, so perhaps you could communicate directly with him.

Smaller profits? It’s Un-American to not use made-in-USA machinery! The Americans have only ever adopted British designs when they had nothing remotely suitable; The Canberra (still in use) and the Harrier.

It’s well known that American mass production was a major factor in winning the war. Strangley, Germany didn’t fully mobilise their population and introduce round-the-clock production intill late in the war, when it was too late to keep up with the thousands of aeroplanes being built in America, where women were a major component of the workforce. This lady was the PR pin-up girl:

Is that aircraft a two seater? Yonks ago we watched one land while storms passed by. The pilot’s young son was shoehorned into the front seat and very unhappy about getting back into the air!

Both of them working flat out at opposite edges of their respective flight envelopes!

There was a pic of three generations of British fighters; each had a major AoA difference as the jet struggled to not fall out of the sky.

That doesn’t seem to happen with my setup; I guess the fine spray nozzle in front of the carby mouth doesn’t see enough pressure drop for it to require a shut-off valve.

Nothing adverse noticed; remember the water is only being injected during full power TO and climb, so only a minute or so. It’s main purpose is to keep head temperatures under control, but hope it will also clean out the carbon. Sorry Ian, can’t take pix; I had a fall onto concrete that resulted in a new hip being fitted, so climbing into plane is verboten for another month or two. Can’t drive and SWMBO is already overloaded with all my jobs, so won’t be asking her to take me to airport. Installation is dead simple: mounted reservoir as low in cockpit as possible (so it doesn’t syphon) and ran fine tube into air filter box, where it mates up with a spray nozzle pinched off my wife’s ironing bottle. Connected pump’s (+) wire to main bus, ran (-) to an alloy strip riveted to side of cockpit, where throttle lever will earth it only on full throttle. Agreed Nev. Next version will inject into a hole drilled in the carby-manifold rubber. I also plan to install a variable control on the panel (next to the CHT gauge) so I can much about with the mixture, plus a few other features.

That’s the main reason for the water; years of AvGas has deposited lots of stuff, on top of the carbon buildup from running slightly rich. Air-cooled 4 strokes are only a short step up from 2 strokes in relying on over-rich fuel to cool the hot bits.

Can’t find my notes, but at least 10C reduction of CHTs and EGTs were quite even. There is no indication of when the water injection stops as I back off the power, other than a clear rise in head temps. On climb, there are three ways to keep CHTs under control: open cowl flaps, ease off power...or go full throttle!

My second version is based on a $28 windscreen washer kit. It operates only at full throttle, so I only have to top up the 4 litre tank after several take-offs. It sprays directly into the carby mouth. I’ve gradually increased the spray rate in ground testing until it’s getting more water than fuel. Still hasn’t put out the fire! After all the efforts to keep ethanol out of my fuel, I’ve been using straight rain water. Because it only operates for a minute or so at full throttle, I doubt icing will be an issue.

Instead of spending squillions importing the toys (which too quickly become obsolete) a clever country would properly invest in local education, training, research and infrastructure… so we have the people and skills to build our own weapons! The most successful nations invest heavily in educating their youth; at one stage, South Korea devoted over 14% of GNP to education. At present, Australia spends about 5%.
