Gentlemen,
You improved the aircraft a lot since my first comment, thank You very much, I start loving to fly it.
My initial critic was not so much about the take off and landing and the exagerated impact of rudder on the ground, witch had probably a lot to do with the sim itself.
I meant that inflight, after properly triming it in smooth weather, without touching commands, the aircraft was deviating pitch and roll and instead of coming back compensating naturally to neutral, it was increasing its deviation behaviour.
And that would not be accepted in real life.
Nevertheless, its getting better and better.
