Which aircraft weapons pylons do I install on my F-15E?

Should I install all of the weapons pylons on my F-15E regardless of whether or not they will have weapons hanging from them?
I have not yet figured out the exact load I want to put on this F-15E, but I have installed the outer pylons on the conformal tanks, along with the inboard pylons and the centerline pylon. Should I also install the wing pylons or is that dependant on how I arm it? Do they leave all pylons on the aircraft at all times or do they take some off if they are not being used?

Thanks

Mike

F-15E’s usually have the inboard wing pylons installed all the time. Depending on the weapons load the pylons either carry bombs, fuel tanks, and/or missles.
