As for the chute, I went with what seemed to be standard for this size rocket.

When I started I was wanting something like the Sunward "INTERPLANETARY SHUTTLE". But I could never get it close to stable at that short a length. I tried loading someone's RockSim file but it crashed. So, I figured it was a Ver. 9 file with new stuff in it.

For the engine tube, check to see if it is referenced to the rear of the main body tube, and not the front. That way, if you change the length of the main tube, the engine tube remains in its correct position. On my revision of your plan, I think I referenced the engine tube to the rear of the body, so it should stay even with the back edge.

If that file you looked at contained pods, then yes, it will crash in Ver. 8. That's the bad thing about our changing to Ver. 9, you absolutely have to have Ver. 9 to read them. Apogee is supposed to be posting the demo of Ver. 9 at some point, but I don't think they've done it yet.
