Third flight of dd2.xls, third attempt at L2 certification flight.  Unsuccessful flight, main charge fired but failed to pull chute fromlower  airframe.  Rocket landed without parachute, damage sustained to fin, airframe and avionics bay.

Flew with Eggfinder @ 909MHz.  Flew with StratoLogger CF and EasyMini.  All data downloaded.

Flew with Mobius ActionCam.

Ejection charge increased to ~0.7g, but it's apparent that the stock 40" parachute in a Sunward 18x18" protector alongside OneBadHawk harness proves too tight to pull out with inertia alone.  No motor eject backup, may have helped with blowing chute out of airframe.
