Crazy rockets contest. Try to build any of the tricky rockets and I'll find some cool prize for you. To my knowledge, none of these have been done before.
  • 18mm Machbuster. I haven't launched mine yet, so give it a try. I'd recommend the Aerotech D21-7 unless can can find an old E25-7 or F55-whatever. Don't try a D24 reload unless you've got multiple trackers with binoculars and a square mile of desert or you like losing 30-buck reload casings.

  • Rama. If you recall, my 18mm Rama model was unstable without fins. (It's currently waiting for a new motor mount and has clear fins.) You could use a canted clustered motor mount to spin the rocket, use a complicated spinning launcher, use a motor and spinning weight inside, or use a spinning booster. There may be non-spinning ways. The only limitations are that it must actually fly, have a 1:2.5 width/length ratio, and have no external fins.

  • Stage to a MMX motor, either from a 13mm (OOP) or 18mm booster or from a MMX motor with the end cap and delay removed. I tried this once with an unmodified MMX booster, but the upper stage failed to ignite.

  • Fly a boost glider with a rubber-band-powered propeller on the glider. I tried this once, but the pop-pod-attachment-hook failed and the powered glider went nowhere.

  • Fly a model of Serenity, with or without fins. My version failed, but I rebuilt, painted, and fully greebled it and gave it to a Serenity-obsessed friend for Christmas.

  • Ignite 2 upper stage motors simultaneously with a single lover-stage motor. I'd recommend D12-0 to A3-4T. Either a clustered sustainer or 2 separating sustainers are fine.

  • Any of the oddball recovery schemes (except UFO) in the next post.

A static photo and basic flight summary for any is fine. Either post in a comment or email me using the link at bottom.
Good luck!
