Ot, but... Rokket, I just downloaded your chopper freebie and I'm seeing alot of smoothing artifacts and ballooning. I noticed that you set alot of the edges on the .obj as hard in wings... This solution does not apply to poser smoothing properly. Next time use control edges combined with bevels (for better specular results) around the various hard edges of the model to avoid this problem and the resulting Poser behavior of the prop. I won't post an image, as anyone who has the chopper can discover this for themselves.

Otherwise, a very nicely constructed model.
