Hey! Sorry for the date, i had stuff to do ;p

This is an awesome way to get a full working artillery.

You need:

Fuselage
Inlet Fuselage
Wing
Pylons (xml sized, little as possible, it won't work if not)
Boom 25/50

Fine Tuner

Step 1

Put your cockpit on the fuselage, size it
Put the inlet next to the fuselage, size it
Put the wing at the end of the inlet (you can use xml sized wings and pylons)
Erase control surfaces

Step 2

Put the first pylon (group 1) at the end of the wing, make it able to throw the booms forward.
Put the boom "" on it, with orbit camera enabled.
Put the second pylon with the boom ""(group2), the third (3), the fourth(...) at the SAME PLACE THAN THE FIRST ONE

Step 3

First, rotate all the bombs in the X axis. (NO MULTI-EDIT, ROTATE ALL THE BOMBS MANUALLY)
Now, go in fine tuner, than do multi-select, multi-edit and move the bombs in the center of the inlet (Y axis). Finish multi-edit and now do multi-edit again: this time, you'll move everything, by sliding it behind. (Z axis)
Put some useless stuff, and even if the plane is mirrored, it will still work!
here is what you will get.

Note: if the pylons aren't powerful enough, you'll need to change them.

I know, this must look hard, but it will take less than 10 mn to build.
