Sounds about right from what I've seen (The yanks have been testing it a fair amount across the lines ) - unfortunately, the DM for the D.XII is pretty laughable...wing-shedding is a pretty huge problem and it seems to be particularly prone to control surface jams / losses (although it might just be me imagining that)...
I was really surprised by the dive characteristics tbh, especially seeing as the Pfalz seems to be referenced a lot as a good diver...it actually feels to me like they've gotten all the Central scouts' dive capabilities a bit mixed up! From what I've read at least, the D.XII dives like an Alb, the Alb dives like a D.VII and the D.VII dives like a D.XII!
And yeah, very nasty spin on the D.XII, actually nastier than I remember from RoF...
Again, I might just be imagining it but it seemed to me (alarmingly) that the full spin wouldn't recover until the prop stopped spinning...!
