Just a heads-up for all the other trekkers on the forum, I'm about to kitbash the Centaur using parts from the Reliant and Excelsior. I'm trying to contact the creators of both kits to ask if I can post the resulting kit in the download section. Hopefully all will turn out well. For those of you who don't know about the Centaur:
