Thanks Muffin,
I have never seen a cockpit video like that before.
I was amazed at the extreme motion on the joystick post rotation just to hold the craft at steady climb. Seemed a bit "ham fisted" to me. But that just shows how little I know.
And perhaps there was turbulence.
Joystick movement at the slower speeds is more than when speed is increased. The control surfaces at higher speeds respond more readily to joystick movement!
