This was me entry into our low-power club's egg loft duration competition. Avast!  T' rules stipulated a D-powered rocket that did nay use parachute recovery (any other method was fine, includin' streamers, gliders, helicopters,etc)

My entry ascended briskly and smoothly, carryin' a large egg.  At ejection, arrr, t' spinner and stabilizer units separated, as permitted by t' rules.  T' spinner section entered a nice flat spin similar t' that o' a fallin' maple seed. Ahoy!  T' descent was nice and slow.  T' spinner section appeared t' float in place for a long period o' time.  T' total flight duration was approximately 30 seconds, me hearties, and t' egg survived intact.

This flight was a real crowd pleaser.  It was also t' winnin' entry by about 15 seconds.
