determining proper thrust
I installed a motor mount on a plane that has had the front end rebuilt on it. I am not sure if the firewall was rebuilt so that the engine mount would have a few degree thrust to the right or not. Is there a way to determine if it is correct or not? If the engine is mounted with no thrust to the right or perhaps a hair to the left, how will the plane fly differently? Does a plane tend to have certain bad habits if the thrust is wrong?
