    Although this was a test of apogee deployment, I rigged the main to go at 400 and put an 8" estes chute in the forward section to get a laugh from the club mates. Chute release unreefed at 300 as planned.

    Nice! Like the straight, vertical column of smoke with the wild blue yonder in the background. My best launch pictures are taken by my rocket buddies too.

    Thanks!

    Thinking on it, I really can't remember if these came from his iphone or the goPro he had set up.

    1 good flight, one unfortunate flight.

    Vertigo II's main deployment performed perfectly on a G77.

    Fissile Missile had a perfect apogee deployment on an F40 (first 29/40-120 use!), but the main failed to deploy resulting in a cracked nosecone, creased payload tube, and a bashed baffle/booster tube. I think I can repair it if I can track down the right PSII parts.

    Charge went off, pin was sheared (although that might have happened on impact). Possible cause; powder leakage. That charge weight was previously flight tested successfully, and I noticed a corner of the tape over the cartridge had come loose.

    This was a productive week off of work.

    I got the Fissile Missile repaired, now its parts are just awaiting temperatures above freezing for paint.

    Next stop on the road to L2: The High-explosive Armor Piercing Incendiary munition (affectionately referred to as the H.A.P.I Man )
    It's the Partizon that's been living behind my couch with a zipperless baffle in the lower coupler, shear strips at the nose, 3d printed coupler ebay caps and sled for an RRC3, and adjustable nose weight. All in all, It's already going to be overstable, so I think the T3 tracker will be living in the nose.

    I'm painting the tip red with a silver band like the 50 cal AP/Incendiary marking and am using my three cans of camoflage drab paint, but I need some outside advice for the paint layout. I'm painting some contrasting faux control surfaces at the back of the fins.

    Beyond that, what arrangement would look good? I'm leaning towards 1 color per tube (excluding fins) to avoid masking, but I can be convinced of other patterns.
    There will be military font wording on the center section in Yellow or Black depending on what color that tube ends up.

    Construction is 90% done, I'm just building up the fillets and awaiting the 3 printed parts.

    Picked up a couple 3d printed lids and a sled for my coupler e-bay.

    The sled has hole patterns for both the RRC3 and the Stratologger CF depending on what I want to fly in it. It'll start with the RRC3 since that's the altimeter I want to practice with in this rocket. There are also slots for ziptieing either a 9v or a 2s e-flite Lipo,

    I epoxied a couple 40 shells to the lids as charge wells, and JB welded eyebolts into the coupler nuts that tighten down one of the threaded rods.
    All that's left is to make the rivet holes for securing it in the airframe and cut the switch hole as soon as I get the switch from Apogee. (switch goes in that cutout that's visible in the battery picture)

    Doofus (me) didn't take care not to flex the tube when measuring the ID of the coupler, so I had to sand the lid's shoulder a tad to get it in there.
