How did you pack the main chute area? Plus where was main chute attached?Regrettably, though the flight was perfectly straight without any deflection, and the drogue deployed perfectly, the HED main refused to come out of the nosecone. A few lessons learned. Re-Reaper will NOT have head-end deployment.
I did learn a few things about temperature, fiberglass tubing, and ejection charges. When the rocket was put on the pad, its internal temperature was 102 degrees, at launch it was 113 degrees, and at apogee it was less than 85 degrees. Those temperature swings can have a significant effects on the separation at ejection, as well as the amount of the ejection charge needed.
I learned something else useful too. Powdered graphite lubricant is not just for pinewood derby wheels, it works to lubricate fiberglass couplers (and other mating surfaces) too. Just wished I had known that before my flight as well.
