Y-Wings have K-turns, let's not forget.
And if you put an Unhinged Astromech on a Scum Y-Wing, its dial becomes better than an X-Wing's.
I don't see how BTL-A4 is bad because "Y-Wings can't maneuver, hurr hurr." The only reason the FFG article is worried about it is because it put BTL-A4 on Drea, whose ability stresses her, which *would* hamper your maneuverability (as it would hamper most ships').
So put the Unhinged Astro, the title and your turret of choice on a PS2 or PS4 Scum Y-Wing and have at it. Might be pretty good.
