I'll post some improvements to the one that's up soon... In the mean time, here's one I just did a cleanup and upscale on: Starstalker-class 2ndary hull http://i1197.photobucket.com/albums/aa421/IanKeldon/Starstalker2ndaries.png
Movie-era Constitution-class saucer mod (again based on Vance) http://i1197.photobucket.com/albums/aa421/IanKeldon/movieeraenterrpisesaucermod.png
ACE series nacelles http://i1197.photobucket.com/albums/aa421/IanKeldon/acenacelles.png and my late 23rd century 2ndary hulls, now with skinnier versions of the larger ones and a "supercruiser" length hull http://i1197.photobucket.com/albums/aa421/IanKeldon/late23rdcentury2ndaryhull2b.png
After extensive consultation with one of the originators of the ACE concept. I have derived a better representation of what was originally intended. The top two represent those, and I did some variants from there. http://i1197.photobucket.com/albums/aa421/IanKeldon/aceconcept5.png
LN series nacelles with "dome" bussards. I mounted a "snubnose" dome, but the "long" nose is included as an adaptor
"Salvaged" a couple of TOS thru-deck cruiser hulls and cleaned them up. Parts credit to Vance http://i1197.photobucket.com/albums/aa421/IanKeldon/Thrudeckcruiser2ndaries.png
