    In post 89 the 2nd pic is motors before flashpan. Masking tape covers gaps between motors. Not shown, each motor nozzle is filled with BP, and then each nozzle has quickmatch laid over it. At one or two points in each flashpan, leave a small opening lined in paper to insert igniter(s). In post...

    Staging went perfectly, with all motors in both stages firing. The 7ft central rocket recovered gently right near the low power pads. All six of the second stage rockets were recovered in perfect condition.

    CMASS Launch - Amesbury, MA - 10/21/2017 A very nice day, reaching the mid 70's, sunny with low winds. The Nitro FireBall lifted off starting with a flash on a big trail of fire and smoke. For the first time, a rockets thrust knocked over my cluster box at the pad. (more pictures on next page)

    Prepped the Nitro FireBall for another 29 motor clustered and staged flight. Built a couple more modified FlisKits Shadowlords for stage 2 rockets. As this involved seven separate recoveries all deploying chutes at apogee, selected motors to keep altitude low for the Amesbury field...

    Recently added a DJI Phantom 4 Pro drone to my personal space program. It's built-in camera's specs: 1in sensor, 20Mpixel stills at 14 frames/sec, 4K video, match the Sony RX10 camera I picked up not long ago. Super fast imaging capabilities. First drone video, done at a friend's house...

    Then the TOGinator went up loaded with a 30 motor cluster: 27x D11-P in flashpans 2x AT F27 red 1x CTI G54 red Lots of fire and smoke to fun effect. Great liftoff. Apogee 871 feet. One F27 not fired, the other 29 ignited. 7 ft Top Flight Recovery chute brought the rocket down. May add nose...

    Prepped the Spinning Saucer of the Apocalypse first, due to low cloud cover. 8x D11-P for spin and 2x AT G64 for lift. Got the saucer RSO inspected. Then looked out to the high power pads... and there were none :wink: Weather was highly dubious in the morning. Very low cloud cover, so...

    Then the Bomarc lifted off on 6x D11-P + 4x D12-5. Another great flight, recovered next to the pad.

    My first flight was the VooDoo Daddy on 4x D11-P + 4x D12-5. Nice hissing smokey liftoff. This was my first cluster rocket built 10 years ago. Landed about 20ft up a tree at the edge of the field. Easily recovered using CMASS' telescoping pole.
