Sorry to hear this. That is a beautiful model. I imagine that even the nose cone took some special innovation to build. Evidently, you did not use the motor ejection as a back-up.
Really interesting project! Good luck and be sure to post some flight video.
Question about the Titan II itself: As far as I know it's the only big rocket that had the engines, pumps, and plumbing all hanging out exposed like that. Does anyone know why they did that?
I know it used room temperature fuel & oxidizer, so there was no risk of big chunks of ice falling at liftoff. Was the reason for leaving everything exposed as simple as that?
Nice flight! I am thinking of using a J270 DMS for my next 4x OT flight. I use a Positive Motor Retention System (PMR-29/38) from PML, which I back-fitted to the model. Since you said that you had trouble with a PML retention system and your DMS motor, I am wondering if I am going to have trouble, too. Is your PML retention system the Positive Motor Retention system?
It's not the only one either. Most rockets do that other than ones based off of Redstone or Jupiter. Those had exhaust vanes, so they needed some sort of shroud for the mechanical parts.The shroud was added on the Titan III to protect the plumbing from the intense heat of the solid rocket boosters exhaust.
Leaving it exposed means saved weight. Saved weight means less cost.
