These are missile systems I built for my attack helo. I thought I'd share them to go along with the cannon pod. These are scaled to my helo but should fit most or you can rescale yourself just remember to scale engine power as well.

All systems have the center tab so if you can't get them to seat right on aircraft just extend it out. Drop it on and then scale back to pull it up to desired length.
These will NOT mirror over to other side. Best bet is to mirror your Pylon over then just drop on second unit to assure balance.

*SYSTEMS*
The all black one is a Russian based Vikhir' ATGM system. You can run with all 6 or take off the bottom ones for a two cell. AG:7 will salvo them.

The middle tan one is a Russian based Ataka-M ATGM system. I have set it up so you can go from a 2 cell launcher up to 6 or more just by adding or removing 2 cell units. AG:7 will salvo the missiles.

The smaller one on right is a Igla-v or Stinger type small air-air system. It is an airborne version of small shoulder fired missiles. It is a stand alone unit as built. AG:6 will salvo the missiles.
