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

Construction:
Parts are very basic and are available from Balsa Machine Services. Ya scallywag! Balsa cone and fins, paper BT-60 body tube and motor mount, arrr, and letramax centerin' rings. Ahoy! Begad!

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

Flight:
I have flown t' rocket three times, ya bilge rat, 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. T' D12-5 worked well, me hearties, matey, but as t' rocket hung on t' launch rod, me hearties, recovery was late. Ya scallywag! No damage resulted however. Begad! I have a few D21-4s, an I plan on flyin' them with a 18-24mm adapter this summer. Begad! Ahoy! See t' RockSim file for recommended and non-recommended motors. Well, blow me down!

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