Hi, thank you for this file. I appreciate your work. However, I'm baffled with a takeoff problem.
Basically, the plane won't lift off until about 190-200kts at reasonable weights. (Last takeoff was around 670-680k lbs or so.) Even when i use higher trim settings the plane will rotate ok yet it just does a huge wheelie until it barely gets off the ground at the end of the runway!
-I'm using flaps 5, full TO power
-Iv'e put in the correct CG
Just can't put my finger on the problem. My flight parameters look nothing out the ordinary.
Any thoughts would be much appreciated!
