I've downloaded the Cessna addon and really like it (works well with the latest Orbiter beta). It offers a more contemplative way of enjoying the scenery than zooming past with a high-powered space-plane .
Regarding the issue you are pointing out : unfortunately, yes, you are right.One thing I find a bit curious is the flight model. If you pull on the stick, the plane pitches up and starts climbing, but when you then release the stick again, instead of settling back into an equilibrium pitch, it just stays at its attitude as if there was a hidden "kill rotation" mode at work. Is this some sort of autopilot setting? I am not a pilot, but from flight simulator experience I wouldn't have expected this behaviour.
Thanks for the link, I'll have a look on this, but... for me it is... hmm... elaborate !I am wondering if this may be an indication that the engine is overpowered. For propeller engines, the generated thrust depends on a variety of parameters (propeller geometry, air density) but crucially also airspeed. For example, this page has some information on propeller performance. According to this, the generated thrust is inversely proportional to airspeed (towards the bottom of the page). So assuming a fixed thrust value won't provide a good flight model. I don't know if the framework you are using to define the Cessna flight model allows to incorporate that effect. But maybe it's something to keep in mind in case you switch to a custom implementation at some later stage.
ThanksYou might try reducing the rotation drag to close to zero, that may fix the attitude issue.

A nose-down tendency could also be caused by centre of gravity vs. centre of pressure misalignment.At first, the aircraft's nose pitched down . I managed to get a compromise, now it stays roughly in horizontal flight.
Max-Q helped me with the flight parameters : it is more compliant with reality.
But yes, when this aircraft is climbing, its attitude remains the same with the joystic in neutral position...
