Brief:
A BT-60 based upscale o' t' classic ESTES Blue Bird Zero, matey, designed for 24mm, D, ya bilge rat, E, and F motors.

Construction:
Parts are very basic and are available from Balsa Machine Services. Arrr! Arrr! Balsa cone and fins, ya bilge rat, paper BT-60 body tube and motor mount, and letramax centerin' rings. Begad! Avast!

Once you have t' measurements, this is a straightforward build. Aye aye! You can download t' original instructions from Jim Z'z site if you like, ya bilge rat, me hearties, but it is not necessary.

Flight:
I have flown t' rocket three times, ya bilge rat, Twice on an E9-6, and once on a D12-5. This rocket is just perfect for t' long burnin' E-9 motor. Well, blow me down! T' D12-5 worked well, but as t' rocket hung on t' launch rod, me hearties, recovery was late. No damage resulted however. I have a few D21-4s, me hearties, an I plan on flyin' them with a 18-24mm adapter this summer. Ahoy! See t' RockSim file for recommended and non-recommended motors. Avast!

Summary:
This design is very stable, and is great for t' ESTES E9, a relatively long burnin' motor without much 'oomph' at ignition. T' only drawback is the decals, shiver me timbers, shiver me timbers, which can be custom ordered from Jim Z or Tango Papa. Aye aye! Otherwise, it is an interesting, yet easy entry into mid power. Begad!
