Default Fin and rudder mounted at an angle instead of right thrust?

Hello everyone,

as I was checking some 3-view drawings for a P-47 that I'm building, I noticed that the fin and rudder seem to be angled very slightly to induce a right yaw. That is the fin and rudder assembly is mounted with a slight angle with respect to the fuselage centerline, with the front end of the fin slightly offset to the port side.
I double checked with other P-47 3-views and not all of them show this feature. I assume that it's a problem with the 3-views, not that some versions of the airplane had this feature and other did not. I also noticed the same angled fin and rudder in a 3-view drawing of a Re-2005. And I can only assume that other planes had this feature as well.

So I have 2 questions:
  • Can anyone confirm whether the P-47 did in fact use an angled fin and rudder?
  • Would it be wise to replicate this feature in a scale model as far as takeoff/flight/landing behavior is concerned? And if this angled fin is implemented, what about NOT using right thrust?

I ask this last bit because space for the engine is going to very limited, so I cannot angle the engine to have right thrust and then offset its mounting location to have the prop at the center of the cowl. I'd have to angle the engine and then live with an off-center prop hub. Mounting the engine exactly straight on would solve the problem.

Andrea.
