Thanks for a number, Skippy. As a starting point I plan to put a air temp probe under the cowl. And in the exit stream. That will give an idea of what is happening. Any other ideas?

Back to ruskie drone engines (and US humvees), I recall that the WW2 americano Jeep was designed with a service life of a handful of hours. But SOME are still in use 80 years later. The fact that a military version is thrown together in haste does not condemn that maker. That particular product IS fit for purpose at that time. It doesn't prove that everything they make is crap (even though it MIGHT be) Anyway, I wouldn't fly behind any Rusky or china copy of a known reliable engine.

Except, few builders will exactly copy an airflow tested cowling. This is no criticism of any builder. Least of all Marty. Obviously, lacking a wind tunnel to assist airflow assessment, the best we can do is ground run, and reserve final judgement until actual real ground runs, and assuming promising results, actual takeoff. If we still harbour doubts, we can temporarily fit extra temp probes, and even airflow measurements. Affordable instruments are now at a level only dreamed of in the past.

What part of "may" did you not understand?

Point taken. Thanks. With outside ambient temp around 16 and engine only running at about 2500 rpm and cowlings off, we were happy to just get the head temperatures up off the stops. Accuracy of readings are yet to be confirmed. Realistic temps might be seen on full power ground runs.

That unfortunate pilot. Sitting out in the weather, navigating with a paper chart on his lap. And so far back that he must have landed by braille. The view whilst taxying... well there isn't one. Gotta admire the skill of those pilots!

Goes around the horizontal stab.... eventually.

A very sad outcome. Condolences to family and friends.

Here's one for you....

I am so glad there are 15 reasons! After all the girls could only find 10 reasons why a cucumber is better than a man.

Fire work takes a special skillset. Low level work (treetops), precision drops, localised crazy wind shifts.... must be exhausting work. Pic of heli work on a fireground I attended last summer. We were often looking down on the choppers! They could drop accurately within metres of us.

I was sailing past Margate, watching the flying circus. Very impressive piloting. There were times when four aircraft were skimming the water, loading on the run. Spray everywhere. Not sure but I heard that they drop about 1200kg at a time. The rate of climb was not looking impressive with a load.

There is still one of these remaining on the Darling Downs. Built in 1931 (?) And flown by several generations of the same family.

When I replaced my stator assembly, it was clearly labelled 'Ducati'. No idea which ducati, though.

The wiring loom was premade. It already has labels on the wires, but since it was premade for a different aircraft, mods must be made to suit a different layout, and some different items. It is messy at the moment, but eventually will be neat and secure.
