Ok, thank you!
The other thing that I was wondering was when you move the stick to the left of right, when banking, it seems to get stuck like that, so the plane stays in a bank while the the stick is in the middle. And then when I want to fly straight and level I have to push it to the other side. Is this with every joystick?
You need to read a whole bunch of cool stuff!
If you throw a frisbee on it's side it will travel in a straight line but canted over.
Your plane will do the same bearing in mind a few things. Thrust drag lift Dihedral etc.
When you roll to the left you are merely rolling the plane using the deflection of
air over the control surfaces. When you return the stick to center you are not doing this anymore.
Therefore the plane will try to continue with this attitude. ( things will effect it though...)
To return the plane to your original attitude you need to deflect air the other way so it
pushes the plane back, rolling to the right.
It is not like a car steering wheel .
We create thrust left and the plane rolls left. We stop creating that thrust and the plane is stuck that way.
Air is just very thin liquid.... hydrodynamics.... etc.
If you were in space the vehicle would continue rolling. To stop it rolling you need to make opposite and equal thrust.
To get it to roll back to where it was you would have to very carefully muck about with your thrusters.
Dunno if this is any help but there are loads of cool stuff on this in your local Library! ( woooo actual books! )
Or you could just read the internet!
