The Big Nuke (2.8" airframe) is a super flyer. One of my biggest scratch-built rockets so far.
Performed well on Estes D & E black powder motors, but it really zips on an Aerotech SU E. Unfortunately, the second flight on the Aerotech motor saw a nice big zipper after a bonus long delay :'(
I'll get around to fixing it some time - it's too good not to try!!
