Hi Yossarian,
1. This might be my error - I had the meanings mixed up, and although Bernt later gave me the correct translations, I can't remember if I updated the gauge code (the perils of having a year-and-a-half break in the middle of a project). I will look into this. Until then, perhaps assume some factory worker sabotage....
2. Yes, the fuel light works, but only at very low fuel (approx 3%), which is different than what is in the gauge code. I suspect this may be a bug.
3. Oil cooler flap: is there one in real life? This has always been a mystery to me, as I have never seen a factory drawing that shows one. In my Messerschmitt factory drawing that shows all the moving surfaces and their degrees and tolerances on the 109K aircraft, including the four coolant surfaces, there is no mention of an oil cooler flap. And as no photos I could find show one, I have just gone with the assumption that there wasn't one. The Flight Replicas late-109 FS2004 models have been out for a number of years, and no one ever mentioned this, either. However, if there was one on the real K, I'll be happy to put one there!
Mike
