Greetings:Having a little trouble getting the 1900C to rotate on takeoff. I pull back at around 105 knots but it takes several seconds of heavy back pressure before the nose will come off the ground. Everything else seems normal.Thanks,crf

CRF,Did you check your V speeds? Maybe you are too heavy for the speed you are rotating at. Sounds like a performance problem, and not a software problem.Tom

Add some backward trim.
