Ed, there is no offset in the engine mount or a trim tab on the rudder to deal with significant P-factor when you rotate with a 520 or 550. You have to somewhat snatch it into ground effect and throw in a lot of right rudder as you keep it aligned with the runway as you retract gear and take off flaps. A lot happening in a short amount of time. Once it is cleaned up through 100′ or so things settle down and climb out is nice with a great elevator-like climb with a low angle of attack profile from the cabin. The view is great and you look at the VSI and it is showing 1200′ per minute climb. Still a fair amount of right rudder to keep it centered.
Best-
