DeathTrap

Hey troopers! My Squad has a rookie in need of some help. He was given FX armor a while ago. (Armor only missing arms) I've tried searching on here to see if any mods can be done to make this armor approvable. Any suggestions or help would be appreciated. 

Question for everyone. How does the 501st and cons work? Are there perks? Do we just purchase tickets as usual and is there a special entry we go in where we can stash our Huskeys? I've never been to a con before and should be approved in the next few weeks. SuperCon is coming up in Ft. Lauderdale, FL and tickets usually sell out. Any info would be much appreciated. :)
