Hi. I'm building two rockets for competition in Turkey. And I have some problems with chute deployment. When I try to separate chutes from the rocket, chutes stuck inside. Or even the nose cone is staying in place. 16gr co2 cartridge supposed to be eject; main chute, drag chute, 4kg payload, and payloads chute. The drag chute is at the top. As I planned drag chute should pull everything from the body. But nose cone is not deploying. Can you give me any suggestions, please?
