I'm scratch building a 5" to 4" 2-stage and have questions about the optimum L/D and angle of the ISC transition. This vehicle is not being designed for super performance i.e. speed/altitude but more for reliability and durability. 98mm motor in the booster and 75mm in sustainer. ISC will most likely be 3D printed using Onyx.
Constructive suggestions appreciated.
