Hey guys I'm a college student part of my school's rocket team. This year we are building a two-stage rocket and expected to reach 10,000ft apogee. One of my concerns is the rocket's stability for a two-stage. I was told a good stable rocket can range from 1.5-3.5 cals. Is the stability the same for two-stage rockets? Reading up on multiple two-stage rocket reports most people start off with 1.8 cals and above, why is that? My team is also having trouble with the stage separation. We are thinking of just doing drag separation but don't know how precise that'll be, so another option is just doing a small black powder charge. What do you guys think, would appreciate your input.
