Great job on that PT-19!

Couple of flying tips, hope you don't mind...

Takeoff: Hold right rudder, slowly advance throttle. As she rolls and picks up speed, ease off some rudder. A little more power and the tail will lift. Soon after, up she lift's into a low angle climb out ! (Right rudder input ends around liftoff)

The PT-19 really has a scale-like, majestic lift off!

Landing: The PT-19 (especially your size) is not a "Floater"! Try a landing pattern big enough to give a long final approach. Approach with a low-ish angle glide path bleeding off airspeed, however, making sure to maintain minimum controllable airspeed. At runway threshold... throttle to idle, level off and she settles right in!
Good Luck!
