I'm experimenting with a cable cutter setup so both charges connect to the same end (nose cone). The nose cone is a standard LOC 3" item. Challenge with polyethylene nose cones is that nothing sticks to them. My idea is to fill the bottom of the NC with epoxy. Epoxy sticks to A/V bay and creates a physical "stopper" that prevents A/V bay from falling out. I epoxy a strap to the A/V bay similar to how some Wildman kits attach straps to MMTs. This solves both the problem of attaching shock cord to nose cone and attaching A/V bay to nose cone securely.
The A/V bay is a sprinkler body which conveniently has a screw-on cap. I laser-cut a bulkhead with relevant cutouts. Terminal blocks connect to altimeter outputs for Main and Apogee charges and two separate switches control telemetry circuit and deployment altimeter. Telemetry includes a GPS which takes several minutes to acquire a lock. I want to turn it on ahead of time and arm the altimeter that controls energetics only at the pad.
