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

Construction:
Parts are very basic and are available from Balsa Machine Services. Aye aye! Blimey! Balsa cone and fins, me bucko, paper BT-60 body tube and motor mount, me hearties, and letramax centerin' rings.

Once you have t' measurements, arrr, this is a straightforward build. Aye aye! 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, Twice on an E9-6, shiver me timbers, ya bilge rat, and once on a D12-5. This rocket is just perfect for t' long burnin' E-9 motor. T' D12-5 worked well, shiver me timbers, me hearties, but as t' rocket hung on t' launch rod, recovery was late. Blimey! Arrr! Blimey! No damage resulted however. Avast, me bucko, me proud beauty! Blimey! I have a few D21-4s, shiver me timbers, an I plan on flyin' them with a 18-24mm adapter this summer. Ya scallywag! Well, blow me down! Blimey! See t' RockSim file for recommended and non-recommended motors. Arrr! Blimey!

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