Ok first impressions of the Ju 52:
'Sitting duck' doesn't even begin to describe it. It might as well be made of pure tin foil. I took down three in a row with one burst each and didn't even use half my ammo in the Yak-1 on my first attempt. I'm also surprised at just how big a target it is and easy to hit despite its slow speed.
It's propably accurate, but it means that Ju 52s used in MP will need massive protection or they'll be shot out of the sky in a matter of seconds.
Also: For some reason the model struck me as somewhat underwhelming. I don't know what it is, but it just appears very bland and box-like. I'm propably being unfair but I guess I was just expecting more visible details

and it's a little bit disappointing that the passenger cabin/cargo hold just appears completely empty.
Still, the Ju 52 is a nice and necessary addition that will certainly be fun to shoot down/trying to protect.
