Hi Chris;
Hmmm. well the logical question is did the two holes on either
side if the camera shroud ever function correctly ? i.e. Were they
occluded in any way by the switches or was the air pressure
non-laminar ? If so, then you really only had two holes total; one of
which could have been
I had nylon rivets between the sections. They need ~80lbs to shear. It
shouldn't have drag separated.

your plight reminds me of my first test flight on my L3 build...
early drogue deployment just after burnout
mine was caused by drag separation of sustainer and payload sections

Um. I like to have THREE pressure portsi.e. just in case.
Here's how (and why):
It seems that this flight qualified as a "just in case" scenario. I
generally make each hole .67-1.0 the size of the specified size of the
single hole specification, all of them the same actual size, and space
This is just speculation, but if the altimeter bay was not properly sealed to
the rear parachute bay,
it could be that at burnout the parachute in the rear compartment continued
moving upward relative to the rear part of the rocket creating a pressure
increase trough a piston effect. (similar
