    This is looking like something from the Master Blasters TV show of a few years back.

    Did you consider flipping the stand-offs so they are aligned vertical to the rocket instead of horizontal. I would of thought that they would not only be more aerodynamic but also stronger in the vertical position.

    BTW an intertesting build, love seeing something other than same old same old, which I am guilty of myself.

    The stand-offs will need alot of stength during mounting of the rocket horizontally on the unistrut rail. Final pad weight will be more than 170 pounds.
    The CG is still an estimate and sits a foot ahead of the forward stand-off.
    I agree with your thoughts about aerodynamics and I did not give this consideration.
    Lying the 2 X 4 standoff flat allowed me to attach them with 4 threaded posts and 2 additional wood screws placed into the bulkheads.

    First flight will be single deploy with one event at apogee.
    The nosecone will separate at apogee and descend on it's own parachute.
    The fincan and payload tube remain connected and they descend as one piece with one parachute.


    Two RRC3 altimeters.
    Black powder ejection charges.

    36 ft. Rocketman parachute for the fincan-paylaod tube section giving this a 13 ft/sec descent rate.
    24 ft. Rocketman parachute for the nosecone resulting in a 10 ft/sec desent rate.

    Both chutes in deployment bags.
    Bags integrated (attached) to the apex of the chutes they carry.
    Each bag with a 30" Skyangle pilot chute.

    Thoughts re this deployment scheme appreciated.

    That certainly sounds like a great plan to me Tom...
    It even reduces the amount of harness you need...
    If your intent is to connect the nose cones chute directly to it then that eliminates a harness there...
    And if the only harness you need is to connect the main chute to the booster / payload section it wouldn't have to be as long..


    Great rocket Tom....
    This is going to be an insane flight for sure.......
