Oh god. Not top trumps again ... Ok I play my "RTFM card" against your "I looked on google card".
Look AD, what I'm trying here is to give you (your team) the best possible info or resuming to make a positive contribute to your project but and unless I missunderstood you post completly, unfortunally my previous post seemed to piss you "a bit" off which again is very, very odd since I'm perhaps one of your biggest supporters/fan of your project, at least I consider myself to be.
And I really find very odd your reply even because according to your info (what you posted) it also mentions that the machine gun that is used in the left and right sides of the Chinook is also the M60D and doesn't even mention the Minigun, so why are you modeling the Minigun? According to your own reply, perhaps you should consider that instead of modeling the Minigun model you should model (and replace the Miniguns with) the M60D
But you want "my card", so here it is:
CH-47 Wikipedia website:http://en.wikipedia.org/wiki/Boeing_CH-47_Chinook
where it says (regadarding to weapons): "up to 3 pintle mounted medium machine guns (1 on loading ramp and 2 at shoulder windows), generally
7.62 mm (0.308 in) M240/FN MAG machine guns"
Note: in this website there's picture of a M240 in the rear ramp of an US Army CH-47 Chinook.
M60 Machine gun Wikipedia wesite:http://en.wikipedia.org/wiki/M60_machine_gun
where it says (regarding the M60D): "In US service, the M60D are being replaced, primarily by the M240H"
US Helicopter Armament Subsystems website:http://en.wikipedia.org/wiki/US_Helicopt...2Guns-a-GoGo.22
Where it says (regading the CH-47's M24 machine gun mount): "NOTE: The US Army phased out the M60D in favor of the M240D and subsequently M240H, but it is unknown whether the necessity of a new cradle for the weapon resulted in the system being redesignated. The mount is otherwise the same. EDIT The M240 utilizes a modified M24 mount system that has been redesigned to accommodate the ammunition magazine and a catch bag for containing expended ammunition casings and ammunition links. It also features an improved roller on the pintle to prevent excessive and premature wear to the mount assembly. Mount system designation remains the same, in spite of such an extensive redesign."
And here are some websites where you can find more pictures of the CH-47 armed with a M240 in it's rear ramp (note that in some of those websites you have to search the desired photos since there is a considerable number of photos in those sites):http://www.wabbaly.com/photography-on-the-front-line/http://military.wikia.com/wiki/FN_M240http://www.ar15.com/mobile/topic.html?b=6&f=18&t=226892&page=13
I even go as far as saying that the M240 is more commonly seen in US Army CH-47 in the left and right sides than the Minigun itself! (Note that I'm NOT against the Minigun by the contrary!)
Honestly I think your data regarding the M60 could be a bit dated, all (or the vast majority of) operational CH-47 Chinook in either Iraq or Afghanistan seem be equiped with M240s and not M60s and honestly I believe that there could be lots of US servicemen that can confirm this. Anyway, as I previously said I was ONLY trying to help!
