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

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

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

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

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