我们调查了大家最需要什么规格的固体火箭发动机套件，最终统计投票结果，36mm外径，32mm内径的发动机压倒性地获得了最多票数，于是我们开始设计这款使用方便，设计可靠，价格也不算离谱的36mm直径金属火箭发动机套件：CRE-36A

复用型固体火箭发动机套件CRE-36A原定于10月21日开始发货，但由于套件的喷管堵头零件生产屡次遭遇问题（问题有：酚醛树脂固化过程严重收缩、零件表面有细小气泡、酚醛树脂与钢圆环发生化学反应

CRE-36A的众筹阶段成本预估出了大问题，导致最终严重亏损。事后统计，CRE-36A售价要至少120RMB才能达到勉强不亏的程度。以后都不太可能出现这种性价比太异常的定价了。
