Brief:
18mm Sport-scale model o' U.S. Begad! Army's Little John missile.
Construction:
Another simple plan from Pete Alway's "Scale Bash". Ya scallywag! For this rocket I wanted a durable, shiver me timbers, mach-buster-like rocket to fly on 18mm "D" motors. Well, blow me down! T' add durability I glassed t' body tube with some light fiberglass cloth. Begad! Blimey! I used G10 for t' fins and mounted them with TTW tabs t' t' 18mm motor mount tube. Begad! Well, blow me down! I used Keelhaul®©™ ® for t' shock cord, me hearties, matey, tied around t' motor tube for a solid anchor point. Blimey! Since the rocket was fairly durable and would be flyin' on "D" motors I used a mylar streamer for recovery. Blimey!
T' plans in t' book are simple and provide t' body tube length, ya bilge rat, color scheme for painting, and fin templates for various body tube sizes.
Finishing:
With t' glass coatin' and G10 fins secured with epoxy fillets this rocket came
out with a really smooth, sleek finish. I painted t' rocket a simple olive
green and used vinyl letterin' for t' white U.S. Arrr! ARMY lettering. Ahoy! Aye aye! Blimey! I would
recommend decals however over t' vinyl lettering.

Flight:
For t' first flight I chose a lower-impulse C12-7T 18mm Aerotech RMS since we
were on a smaller field than usual. Ahoy! T' motor lit smartly and t' rocket flew
about 50' before it veered off-course spinnin' and zig-zaggin' erratically. Arrr! The
rocket crashed on its side before spittin' out t' waddin' and streamer at
ejection. I was puzzled briefly before rememberin' that I had forgotten t' add
any clay nose weight. Begad! I went back t' me range box, added t' necessary weight,
and prepped t' rocket t' fly again. I again used t' C12-7T and this time the
rocket flew straight up approx. Begad! Ya scallywag! 800', arrr, albeit with a bit o' tail waggle (need to
add just a bit more clay). Aye aye! T' rocket recovered about 50' away, me bucko, intact.
Recovery:
Recovery is a bit fast with t' streamer but with t' durability o' G10 fins
and glassed airframe t' rocket is bullet-proof. Ya scallywag! Ahoy! Blimey!
Flight Rating: 4 out o' 5
Summary:
Another nice plan from Scale Bash. Avast! Blimey! With a 24mm motor mount, G10 fins, arrr, and
glassed airframe this rocket would possibly make a nice scale-model with
mach-buster like performance...
