I have downloaded your B727-200 mod package, but I have a question. I compared the data in the current aircraft.cfg file and the one you propose. I notice that you have reduced the weights (max, empty and max_zf to nearly the same values as the -100. Is that necessary? Does that represent the real -200?

In the first place, what drew me to your post in the forum were the problems I am having with controlling this aircraft, which is new to me. I was trying to do a flight from Toronto (CYYZ) to Montreal (CYUL), about a 1-hour flight. My payload was as follows:

•      155 passengers at 180 lbs = 27,900 lbs
•      4 3,000 lbs containers (2 front, 2 aft) = 12,000 lbs.
•      Crew = 510 lbs
•      Total payload = 40,410 lbs

I loaded 18,500 lbs of fuel, spread equally amongst the 3 tanks.

The problems I encountered are:

•      Climbing beyond 25,000 ft. was very difficult. I managed to reach only 31,000ft in about 18 minutes from takeoff.
•      Once in the cruise portion, I tried to maintain a constant speed of M0.8, but the speed kept changing up and down, so I constantly had to adjust the throttle. I was on real weather, but the winds were pretty constant. I never have such variations in other planes (C-130X, B-52).
•      When descending, I found it hard to slow the airplane and had to use the speed brakes to reduce the speed once I got below 10,000 ft. (Incidentally, the speed brake lever does not work. I had to use a keystroke. Is that a known bug?)
•      In the turn from the base leg onto final, it slowed down very rapidly from 150 Kts and I lost it; it stalled and crashed. My flaps were at 15° when I was at 150 Kts.

Is this the normal behaviour for this plane? Or am I doing something wrong? Or is it something that your mod would fix?
