Ok, so I am a NOOB at this, but I finally got my 48" scratch built model to fly straight up to 1,700 feet and come straight back down, but it took me 87 launches to get this far and I am sure that I have not optimized everything that I need to optimize. And, I can only get the 1st stage of the rocket to light, not the 2nd stage. Is it normal to have to run that many sims to get to an at least partially optimized flight?
