Ah ok. In that case select the tail object, and on object menu, optimize vertices and surfaces. Triangulate anything that has a concave surface (surface menu?). If its still black there after that check to see if there are any vertices that don't belong. Select invidiual or pairs of vertices and make sure that the "vertices selected" number in the upper left is what you expect. Some can't be fixed. So if all else fails, go into surface mode. Select that one surface and delete it. Then select the vertices that you want to be in the replacement surface (use CTRL+left click in the 3d window). Select them in counter clockwise order. Then select "create ordered surface" on the vertex menu. Make the surface single sided. If it disappears after that then select "Flip Normals" on the surface menu (they weren't counter clockwise). Generally you want almost everything single sided (except the occassional fin or door poly. Also any object that is a single surface needs to be triangulated to prevent plib from screwing it up.
