Hopefully this is the proper forum for this question. I'm running P3d v4.5 and today I had my first attempt at flying Manfred Jahn's remarkable C-47 3.14 over the Andes. I couldn't get over the range as I was just running out of power trying to get above 15k ft. The aircraft was fairly heavy (28,000 lbs plus) and by the time I more or less clawed up to 15,000 it was just able to hold altitude but was having to fly so nose up it was ridiculous. I had the throttles firewalled and was only getting about 26.5 MAP and tried a few different RPM's. My IAS was about 90-95 kts and I decided there was not much sense trying to get much higher. I was really started when I went to an outside view to see the plane hanging on it's props at about a 10 to 15 degree AOA. I know they flew these things over the Hump and I seem to recall the plane had a ceiling of over 23k. Has anyone else experienced this?
Thanks in advance
