DCS: FC3 - AIM-54C Phoenix on F-15C...I shouldn't ;) 

You're right. The missile falls away from the aircraft before the rocket motor ignites. Not only that, but the Phoenix also climbs and goes up to a much higher altitude before falling towards its target. I think that they only show a fire mode for short range, but still use it for long range intercepts... Oops... Small error in the DCS programming I guess? :)

probably cuz the phoenix is meant for the f14 anyway and since we dont officially have an f14 they didn't put too much time into the weapons systems. I figure if we ever get an f14 they'll fix the phoenix.

You don't need to download anything. You only need to change something in the F-15.lua ;) What? Google it!

Basically you have to edit the lua file for the plane. Theoretically you can load every weapon on every plane I think, but you can't actually fire every weapon. And with DCS 2 I don't even know if it's still possible.

Supertomcat I got version 1.5 ( Caucasian map ). I got a huge request to you. Could you try to add AIM-9 and MICA to Mirage 2000C and test it? Or just tell me excatly how to do it.
