These are legacy ones. The fight at the moment is with the drone industry, why can't they go there and fly to 1500 feet AGL just like a model aircraft can especially when they are multiple he more sophisticated in technology. My guess is all of these will be wiped out in the coming year as soon as CASA gets around to doing it and they will be back to 400 AGL unless it is an approved rocket launch area https://queenslandrocketry.com/ "the only launch site in the Southern Hemisphere which allows flights up to 120,000 feet (36 km)." Well there you go! From their website

Thats a drone category < 25 kgs. and unless its a CASA approved test site there will be no chance over 400 ft agl

The only way they would give approval is for rocketry operations. They would not get approval for model aircraft to fly above 400 feet except by application to CASA, NOTAM etc... Cost = $$$$'s Rocketry operations are really the only exemption that you can get but they must be approved in very small windows, Notam etc. required. Rocketry is very different to model aircraft. note: there may be some legacy approvals in place as you have mentioned above, but I know since all of the new regulations were introduced it is not going to happen now.

What the feeling locally in Goulburn ? Burn him at the stake or a tragic accident ?

Please say hello to Richard for me !

it's what 99.999999% of Australia knows as "Fraser Island" before we became politically correct

there are lots of differences in the fuel numbers in the way they are measured around the world and many people get confused 1. RON (Research Octane Number) Mild test conditions Higher number 2. MON (Motor Octane Number) More severe test (high speed, load, temperature) Always lower than RON 3. AKI (Anti-Knock Index) — used in the USA This is the average: AKI=RON+MON2AKI = \frac{RON + MON}{2}AKI=2RON+MON That’s why US fuel numbers look lower: US 87 ≈ Australia 91 RON US 91 ≈ Australia 95–98 RON this means when you look at a number in the manual you need to make very sure whether they are talking US numbers or Australian numbers! not being able to work this out properly could mean that you are using a lower fuel grade than your engine manufacturer stipulates

you can further the grade the engine performance slightly in this situation by turning off one ignition circuit. It's not much but it helps

Nice Drawing.

Maybe Amp Meter ? How much power he is pulling from the system. Just a guess.

warm it up (the thermostat) with a hairdryer/heat gun until it's nice and toasty and then add your oil ??

no

I don't think you are correct with the Woodcomp props, they are manufactured in the Czech Republic and I doubt they were ever fitted to the original gazelle aircraft in the 1980's. Woodcomp are still in business, so there should be no issues in getting them but I am 100% sure they were not fitted as standard equipment to the gazelle aircraft. WOODCOMP came into existence at the end of the year 2000 as a result of the merger of the two largest producers of aircraft propellers in Czech Republic having the rich and long-term tradition.

I know this, but it came from their FAQ section

(turbulence) It has to be if what you are balancing is vibrating. Changing pitch alters: Blade aerodynamic center of pressure Torsional load on crankshaft Gyroscopic forces Engine firing pulse coupling Blade flex characteristics So even though the mass imbalance doesn’t change, the way forces transmit into the airframe does. and for best results you must do the balance at cruise rpm AND cruise pitch, most probably while flying ? If you balance in fine pitch but fly mostly in coarse pitch: The aircraft will still vibrate in normal flight. From the Dynavibe manual FAQ's
