Just tried it out and there are some major flaws in the model as well as in the hardpoints ... l net's brake it down to points :
1. secondary hull is not alligned to center with saucer
2. Sovereign nacelles have some nasty smoothing errors
3. there are multiple texture misallignments
4. aft launcher is not set on the model properly
5. saucer is a bit too big for the rest of the ship
6. nacelles texturing style is clearly different and doesn't match with mine textures
7. hardpoints are way, way, way, way, way ... waaaay too strong, remember Krakow ? it was at least as strong as Akira class but not stronger while with Solaris I managed to beat the hell out of 2 Scimitars without getting damaged.
pics of all model/texturing issues below.
