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

Construction:
Parts are very basic and are available from Balsa Machine Services. Well, me bucko, blow me down! Balsa cone and fins, matey, me hearties, paper BT-60 body tube and motor mount, me bucko, ya bilge rat, shiver me timbers, and letramax centerin' rings. Blimey!

Once you have t' measurements, this is a straightforward build. Ahoy! You can download t' original instructions from Jim Z'z site if you like, arrr, but it is not necessary.

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

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