How do I get RockSIM to play nice for me?? I need that bottom main body tube to disappear so that the fins attach to the motor mounts. There should only be one 2.25 inch body tube.

Nosecone looks like a Balsa Machining hollowed nosecone. Shoulder is definately made of balsa. Inside the hollowed nosecone is some ugly black hard rubber junk. Might have been an attempt at nose weight or maybe internal anti-crush support for the NC.

When I get back home today, I will take better pics of that NC.

Tony,

I think when I built similar designs in RockSim I used a "phantom" tube inserted in the middle of the motor tubes with a zero weight with the od of the phantom tube used to seat the fins against. It is difficult to explain. I will try to take a look at your RockSim file and get back to you.
