    Hi All,

    So i started the build of my Estes Big Daddy yesterday.
    I wanted to change some things here and there and share it as well.

    1. I wanted to change the bulkhead which are cardboard from the kit. Little design and cut from a 1/8" plywood sheet with some lighten area. (sorry, really bad picture and epoxy gluing)

    2. Found the body a little incomplete so i designed a 3D printed tailcone.

    3. Because i'm cheap, i designed a 3D printed motor retainer as well.

    4. I'll be adding a real parachute, kevlar shock cord and reusable wadding.

    How much weight does that add to the tail? Any concerns about having to add more back to the nose?

    I haven't weighed the bulkhead or any other parts yet but since it's a really short rocket, I suspect a need for some weight.

    Yet, the bulkheads are very hollowed and the 3D parts light.
