Hi I'm new with Lock On Flaming Cliffs 2 and I am trying some MODs for it. I have tried both Bomber's MOD and EfA 2b MOD (not at the same time), and when I fly the B-52, B1, F-117, etc I just don't know how to open the bomb bay... could someone help me please? Also, with one of thes Mods do you think is better? Thanks
