If the parts with the little fins on it could rotate you could say this is an upgraded Excalibure that also uses rotatable engine parts like the Vampire or Panther from Prophecy.
Could be quite interesting ^_^
Improved pitch and yaw would be the first things that would be improved and with that possibly better prophecy armor, sorta a big brother to the original.

Originally I was going to have two classes (an upgraded Excal. and a modified thurst vectored sibling Excelsior class, but I ended up throwing them into one.
This is awesome.
Unfortunately, FS won't be able to make those parts move like engines on Vampire. (at least not without scripting)
Yup, I've made requests in the past. I've got several fighters that could use it (vampire, valkarye, falcon, viper and now the excal. Also a possible thurst vectored raptor is a possibiliy).
