FG-19 R3 Break-in

Break-in of one of my new FG-19 R3 gas radial engines. The second one will follow shortly.
Using 15:1 oil mixed fuel, it burned app. 1.5 l with a very rich mixture with 2000 rpm at full throttle for about 2 hours.
With a 14x7 APC prop, it now runs from 1400 rpm at idle up to 9500 rpm at full throttle, still using 15:1 mixed fuel.
Later, it will run with 20:1 mixed fuel and a 3-blade prop for my 2.4 m B-25.

Are you flying the engine yet? Going to buy a Keleo exhaust ring for it?

Hi Tim,
No, I haven't flown it yet. I have too many other projects ongoing :-). I will use two FG-19 R3 for my ESM B-25. I'll use the exhausts that come with the engine and I'm pretty sure that I'm still below the noise limit of our air field.
