hi I am maneging to model the flight dynamics of my plane which has canards.

The only problem now is that, when I move the joystick down the plane pitches up and when I move joystick up then it pitches down.

Does anyone know how to solve this?

it is not an animation problem. The animation is fine. Is a dynamics problem when I fly the plane. Instead of going up when I pull the joystick it goes down.

Canards function like elevators, except they are used in some supersonic aircraft during low speeds, such as in landings. Therefore, your motions are correct, if they move like an elevator, in pusing the planes nose up or down. If the animation part is correct, along with the proper "tags", you are right in the air.cfg and aircraft.cfg files. Especially, when your plane is moving in the opposite direction then your joystick. You might look at microsoft's concorde, which uses canards and see how the air and aircraft files were done. From what I see, there is really nothing in there that would reverse direction. You could also look at the aircraft container sdk from microsoft to see if there is anything.
Hope this helps a little.

Thanks for your replyes guys.

Well first this is not an existing aircraft. This is a conceptual design that we are doing as part as our aeronautics degree. And it is not a supersonic one.

The problem is not an animation problem, as for this I reverse the axis so canards move the way that they have to move.

I think what I have to do is to simulate the as an a horizontal stabilizer, this is what most people have done for a canard configuration plane within FSsim
