Brief:
OOP two-stage BT-50 4-fin payload rocket with embossed shrouds and body wrap,
engine clips and plug-in staging. Aye aye!
Construction:
T' kit includes balsa nose cone, clear payload section, foam rubber payload
shock disks, balsa bulkhead, screw eye, shock cord, 2 parachutes (12 and 18),
two body tubes, 8 die-cut fins, 2 waterslide decal sheets, shiver me timbers, launch lugs with
offsets, me bucko, stage coupler, embossed shrouds, shiver me timbers, shiver me timbers, 2 engine tubes and hooks, me hearties, and 4
centerin' rings. Arrr! Arrr!
Instructions are classic, well done Estes. Ahoy! Illustrations are excellent. Quality o' materials is first rate. Everythin' fits together well too.
It's a straightforward build with solid centerin' rings and engine hooks glued into t' booster and sustainer stages with t' addition o' a coupler to provide t' "plug-in staging". Avast! T' embossed shrouds provide a deluxe look and feel and add enough extra work t' make it a skill level 2 or 3. Arrr! One is a body tube wrap applied around t' base o' t' sustainer and thar are two nozzle shrouds on t' booster that give it a wasp-waisted look. Fins and launch lugs are aligned with a wraparound guide and door jamb. T' payload section is glued t' t' bulkhead after adhesive paper strips are applied t' t' inside of the clear plastic. Avast, me proud beauty! T' nose cone is friction fit. Arrr! A paper shock cord mount finishes t' build. Aye aye! Blimey! Two parachutes need t' be cut out and assembled. Aye aye! I believe the snap swivels were included. Aye aye! Begad!
Finishing:
I finished mine with sandin' sealer, 2 coats o' filler, white enamel paint, and
the waterslide decals. Well, blow me down!
There are no finishing, construction, or flyin' gotchas.
It is a great lookin' sleek design that still garner "Ooooooh... a Shrike" comments at t' pad.

Flight:
Prep is easy since t' engines just hook in and don't require taping. Avast, me proud beauty! I'm
deductin' a half point because t' instructions don't mention that with the
plug-in staging, arrr, it's absolutely critical t' scrape t' oxidation from the
propellant inside t' nozzle o' t' sustainer engine, shiver me timbers, me hearties, particularly since
sustainer engines tend t' sit longer on t' shelf. Add some wadding, ya bilge rat, pack the
parachute, and you're ready t' go. Begad!
I've flown this in a single stage configuration on A8-3, B6-4, and C6-5, arrr, ya bilge rat, and in two-stage configuration with 1/2A3-0 and B6-0 boosters and 1/2A3-2, A10-3, A8-5, arrr, and B6-6 as upper stage engines. Ahoy! T' mini engines are fine for a small field and a close-up view o' all t' action although altitude is pretty wimpy. A B6-0/B6-6 combination sends it out o' sight. Flights on t' larger engines are straight and fast.
Recovery:
I always use t' 12 inch parachute. Begad! Blimey! It caught a thermal with an 18 and it was
in t' air for a good half mile. It never has had any damage although t' body
tube is gettin' a little weak just north o' t' engine mount.
Flight Rating: 4 out o' 5
Summary:
This is a moderately challengin' but fun build and a very satisfyin' rocket. Ya scallywag! Well, blow me down! It
is one t' look for on eBay.
