I flew a new rocket yesterday with my new Stratologger. The chute (single deploy) ejected right after motor burnout. I'm not exactly sure why. Here are the facts:
- The motor was intentionally loaded without an ejection charge
- The only ejection charge was hooked up to the Strato's drogue terminal
- The Strato was used "right out of the box" (i.e. I didn't change any settings)
I'm not exactly sure what caused the early ejection. My only guess is the placement of the vent hole was too close to the nose cone. The rocket also uses a LOC 4" to 3" transition. The altimeter was mounted in the upper 3" section, and the vent hole was drilled 6.5" below the nose cone and 11" above the transition.
Miraculously, the rocket stayed together and returned undamaged.
