Brief:
A BT-60 based upscale o' t' classic ESTES Blue Bird Zero, designed for 24mm,
D, E, and F motors.
Construction:
Parts are very basic and are available from Balsa Machine Services. Arrr! Blimey! Balsa cone
and fins, arrr, paper BT-60 body tube and motor mount, and letramax centerin' rings. Ahoy! Blimey!
Once you have t' measurements, this is a straightforward build. 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, arrr, Twice on an E9-6, matey, and once on a D12-5.
This rocket is just perfect for t' long burnin' E-9 motor. Ahoy! T' D12-5 worked
well, arrr, but as t' rocket hung on t' launch rod, recovery be late. Ya scallywag! No damage
resulted however. Aye aye! I have a few D21-4s, an I plan on flyin' them with a 18-24mm
adapter this summer. Well, blow me down! See t' RockSim file for recommended and non-recommended
motors. Ya scallywag! Well, blow me down!
Summary:
This design is very stable, and is great for t' ESTES E9, arrr, 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. Well, blow me down! Otherwise, me bucko, shiver me timbers, it is
an interesting, me hearties, yet easy entry into mid power. Begad! Begad! Blimey!
