So I just kit bashed a big daddy (plywood, then glassed the body tube and tip to tip glass) with a 38 mm motor mount. To gain some space for recovery, I cut the bottom on the nosecone off, and used a coupler tube and a bulkhead to create a removable bay in the nosecone (and on the forward side of this I designed a sled for my eggfinder mini).
Depending on the motor length, there is minimal room left in the body tube for a parachute (there's plenty of room using the area inside the nose cone. Currently I just have a single 12' kevlar shock cord with a swivel tied on about 3 feet from the nose cone for the parachute. LOC/PML has a new design (bumblebee, https://locprecision.com/collections/public-missiles-kits/products/bumble-bee-rocket) that has a very similar design. They appear to add an extra length of shock cord, but overall doesn't look much different.
What can I do to make sure when the motor eject charge fires, that the parachute is pulled out (will likely be sitting kind of halfway between the body tube and nosecone in most cases? My first instinct had been to put as much of the shock cord forward so when the nose cone separates, the unraveling shock cord will pull the parachute out. Just curious what other people have done.
