Looks awesome Layne, Do you have a flight date set?
Nothing set in stone at this time, but Troy has been trying to get me to come to AirFest.

Yes. You only need a little over 0.5" to attach any Slimline retainer.
Hari H. Krishna this thing is big, compared to the motor sizes I am used to.
This is going to be glorious...
The Heavens shall open...
And my Ballz shall fly!
Deep, cleansing breaths, Layne.
Step away from the llama, Layne.
No, Layne, step away from the lla....
Did you change your charge packing method between your last test and the current test? Changing the degree of confinement on the black powder (e.g., more wraps of tape, tighter charge packing, different charge container) will definitely change the results. Also, make sure you ground test with everything in its close-to-final recovery configuration; blowing the nose off is much different when the charge also has to shift the chute/wadding/cord/protector, too.Today I tested the four pins with 2 grams of FFFFg powder.
Boy was I surprised.
BOOM!
<snip>or the airframe halves will beat each other like like step children on decent.

Hope someone has a camera handy when that goes down.

Good luck with the flight!
Nice lookining rocket. Good luck with the flight!!
Not necessarily..At apogee most likely the 2 parts of the rocket will be on the same plane horizontally..Unless you have a really large drogue or a LOT of SC between the drogue and the aft end of your avbay that would allow the forward section to 'fall' and maybe come in contact with the aft section..
I think the most likely scenario with your rocket is that at apogee event, the fin can(since it is pretty draggy) will be slightly above the nose section, if going drogueless(my preferred method BTW)..Having the small drogue close to the aft end of you avbay should keep it above the fin can and out of harms way when the main charge goes off..BTW, I use 'pop rivets' to secure my avbay to the upper tube housing the main(dirt cheap at McMaster-Carr, part # 91020A218)..

Is this closer to what you suggested? Moved the 24" PML drogue close to the avbay. Also moved the NC closer to the avbay as well. ANd using chadrog's tape trick should take some of the shock out of both events.
Ordered the 2-56's today for the separation between the upper airframe and the avbay at main chute deploy.
