Looking at various pusher aircraft I notice different thrust vectors angles. Rutan's pusher aircraft have the engine mounted 2° upwards thrust because the engine axis is slightly above the CG cord an so the upwards tilt is implemented to cancel a downwards pitch when power is applied.

In contrary the DC9 thrust vector which is above the CG is downwards. One would think that it would cause the DC9 to pitch down when power is applied which is not the case.

Explanation appreciated.
