Not trying to be a smart-butt or anything but has there been any thought to the idea that maybe it just does not have enough speed for take-off when you take-off?
I have watched many a jet look really bad at Top Gunn, Florida Jets, and monster planes simply for lack of speed at the moment of becoming airborne.
No matter the amount of deflection, airflow is still required. And you did say it flies well once up to speed.
