yes we have a few planes with 4x20mm package,yes we have the data already available,NOW lets get it in more aircraft that DID have this gun package and DID see combat. we have the f4u-c corsair(only 200 produced) but not the option for the f4u-4 with 20mm x4 package(it was called f4u-4b with 297 produced in 1944),several marks of spitfires had the 4x20mm gun package(the f.mk vc,lf mk vc,spit xiv,etc)depending on what wing they had.we have some of these in game,lets get the option.ki-84 also had a 4x20mm variant...ok lets do it.and p-51 mustang had a 4x20mm variant called na-91 mustang 1a,150 produced,93 delivered to RAF,the rest retained by usa later converted to other roles. for some it is a question of why,for me why not,the aircraft are already in game the daTA Is TOO ,JUST ADD THE GUN PACKAGE.we should let the pilot decide what HE wants to fly rather than the community tell the pilot what he cant fly.and yes some production models are made in low quantities AND are already in game,f4u-c(200),ta-152(49 made),p-47m(130 produced),fw190d-9(674 produced).
it seems that these would be good updates......and on another matter please 2x20mm cannons on the ju-87
