Mosquito is not quite a figter and not quite a bomber.
Personally I dont understand why we need to see the 3D outside view setup in terms of "hard categories", why just not model it individually and logically.
Take the dedicated bomber version of the Me262, this plane was clearly a bomber, issued to bomber units, and used as such. Should it have an external view just because its a "bomber"?
Once again I dont see why the 3D external view must be coded into categories, just do it individually and leave it to logic.
Look at it this way.
If the Me110 came into the game, would it have external view?
Historically it wasnt a bomber, so it would fall into the "fighter category" and then wouldnt get one. Yet by alll logical means it has the same view setup or better than the Mosquito, which is in the "bomber category" and gets a 3D view.
Just model it individualy and logically. Or if you want to have "categories" create a "sub category" in bombers for planes that cant logically have the 3D view of the B17s Lancs etc.
I can see the following "bomber" type planes or multi seaters not having the 3D external view.
Ar234
Mosqito
Il2
Me110
Me410
Hs129
Beufighter (maybe)
Ki45
Forget this illogical and rigid "category" nonsense just set it on/off in individual planes.
Now I admit I have no idea what this involves from a programing perspective, but if the HTC crew are still the same people who made AH run extremly well and be stable on my sputtering and dying old POS 333Mhz PII with ancient Voodoo card, then I honestly cant see this slight change posing any trouble whatsover for them.
