XFY-1 Pogo in RockSim-9, redux

On my previous iteration, I formed the upper section of the body (the body's cross section is oblong) with a single thick fin. This left noticeable gaps. In RS-9, you can add components internally so they will seamlessly protrude from a body tube. In the revised model, I started the fin about 1/2" inside the body tube and extended the height by the same amount. The sides of this component are seamless and the ends are improved. You can still see a half-moon shaped divot in the attached rendering. If the main body was wider or if the added section were shorter, then this would look better. Too bad rendered fins don't reflect an airfoil. I played around with a cone/tail cone pair, but found the fin looked better.
