About as often as the Falcon shot off its radar dish.
Sure the TIE's wing obstruct more but it's the same principle. And I guess the warhead launchers are in the heavy weapons turret.
Though I would love a seperate model for /sf I would be happy with a title that allowed firing out of arc as well as adding missile/torp slots, and maybe even boost (but that's probably overkill). Migh want to add another hull too. Hmmm, sounds like that title will cost about 5, 10 or more.
Thing with the falcon is
1.) Two turrets (top and bottom)
2.) A LOT more unobstructed space to shoot
The tie/sf has a single (almost phallic) turret below the...cockpit
Only way it's not shooting its wings off is firing at targets in front, behind and below
or if it flips to the side and then shoots like its shooting below
