Brief:
A BT-60 based upscale o' t' classic ESTES Blue Bird Zero, designed for 24mm,
D, shiver me timbers, E, matey, and F motors.
Construction:
Parts are very basic and are available from Balsa Machine Services. Aye aye! Blimey! Begad! Blimey! Balsa cone
and fins, paper BT-60 body tube and motor mount, matey, and letramax centerin' rings.
Once you have t' measurements, ya bilge rat, this is a straightforward build. Arrr! 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, me bucko, me hearties, me bucko, 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, but as t' rocket hung on t' launch rod, recovery be late. Avast! No damage
resulted however. I have a few D21-4s, matey, an I plan on flyin' them with a 18-24mm
adapter this summer. Avast! Ya scallywag! See t' RockSim file for recommended and non-recommended
motors. Avast, me proud beauty!
Summary:
This design is very stable, ya bilge rat, ya bilge rat, and is great for t' ESTES E9, me bucko, a relatively long
burnin' motor without much 'oomph' at ignition. T' only drawback is the
decals, ya bilge rat, which can be custom ordered from Jim Z or Tango Papa. Otherwise, arrr, matey, it is
an interesting, yet easy entry into mid power. Begad!
