There are A couple of important things to note about using this mod you need to consider.
1) The current Gazelle Lua is locked.
No edits are possible
2) This mod, when installed correctly, with replace this lua.
However, there are consequences to doing so.
First off, you will lose any and all improvements to the code, especially the FM section.
This means she will behave as she used to, or at least, not as the new version intended.
I do not know what other systems will be affected.
All mod contents use each other to make a whole.
Change one, affect them all in some way
3) Because the Gazelle was not meant to carry these weapons in the sim,
It is missing any radar or tracking which the weapons may require to find a target.
The mod was originally created as a "What If" just to see if it would work.
To our utter surprise, it does!
One final note.
The mod was not created by me.
I only made the suggestion, and showed the missiles in sim near the pylons.
The others did all the code work for the original mod.
