I am going to try and scratch build my first 2-stager hence "Initiator" I already am HPR L1 JR certified and have some experience building rockets from scratch(if you don't try new things you won't learn). my ASP order should arrive tomorrow but I already have fins cut out and an open rocket file made. Anyone with experience flying a 2-stager please download the file and voice your concerns here are a couple things that need to be addressed:
1. still don't know the final dimensions of the nose cone(or weight can always add some) because it is part of that Estes plastic nose cone assortment that's part of the ASP order.
2. motor retention on the sustainer is still a question, I am thinking of using a hook and just cutting a slot in the booster motor mount tube to allow the sustainer motor w/ hook to slide in (might 3d print and ABS ring around that slot to keep up structural integrity.
3. should I use a kevlar cord attached to a centering ring for my shock cord or a 1/4" elastic shock cord mounted by the "teabag" method?
