Another issue that could play here too. The speed you are at when you try to turn the plane. If the plane is moving too fast when you try to turn it can and will "flex" the spring out like you say. To be honest, that is what that spring is for, to absorb the forces that would otherwise transfer to the fuselage and damage it. If you are moving too fast it will pull that spring out like that. And like I said above, if you do it too much you will weaken that spring and it will become easier flex with less force<div>
