I updated the RockSim file in my original post with the information that Bill provided. I also suggest building this heavy rocket with at least a 24mm motor mount. The lower thrust motors don't give this model much speed at the top of the launch rod; even a 24mm E9 motor only gives about a 26mph speed at the end of the guide, and the D12-3 only 30mph, see attached RockSim file for details. I also attached a screen shot of the 24mm motor simulation results and the 3D view of the model I simulated.
