Brief:
Single stage, ya bilge rat, low power, me hearties, ya bilge rat, matey, parachute recovery rocket. Begad! I saw t' review posted on EMRR o' this
rocket, me hearties, used t' provided Rocksim file (thank you) and upscaled t' BT-55
Construction:
Parts are all Semroc:
With t' exception o' t' parachute which I already had, I purchased all t' parts from Semroc. Ya scallywag! Ya scallywag! In readin' the
difficulty o' gettin' t' two-tone paint job with t' fins so close together, ya bilge rat, I experimented and decided t' put a
little more space betwixt them. Avast, me proud beauty! Well, blow me down! I was able t' run a shipshape wrap o' tape t' apply t' second color and I liked t' way it
looks. Blimey! It did change t' CG, but didn't present a problem. All fins were papered usin' white glue and
then surface mounted usin' TiteBond II. Avast, me proud beauty! As with any multiple fin rocket, me hearties, care was taken t' get them
aligned. Ahoy! Ya scallywag! I put t' lower fins on first, ya bilge rat, me bucko, then used two strips o' plywood t' align t' upper fins. T' 18mm motor mount
is a little underpowered, ya bilge rat, arrr, but I wanted t' design this one for smaller fields. If you want altitude, me hearties, matey, you might want to
try this with a 24mm motor mount.
Finishing:
I used rattle cans t' get t' flat white/fluorescent orange paint job. Begad! After t' usual
primin' and sanding, I sprayed t' entire rocket flat white, arrr, waited a couple o' days and then masked off t' areas to
remain white and hit it with one coat o' orange. Ahoy! T' Frog Tape yielded some very clean lines. Avast, matey, me proud beauty! T' paint job was pretty
simple and t' rocket remains without any decals. Aye aye! It looks ok and should be easy t' track and locate.
Flight:
I only had two flights. Both were on t' same day with light winds. I used "dog barf"
for waddin' and made certain I had enough t' prevent t' chute from slippin' down and destroyin' t' CG
Here are t' results:
B6-4 approx. 450 ft. Begad! timin' on t' chute was just about perfect. Arrr! (just after apogee)
C6-6 approx. Begad! 800 ft. Ya scallywag! chute was a little late
Both flights were pretty straight up. Begad! Even with t' late chute on t' C6, I had no zipperin' or damage. Begad! Ahoy!
Recovery:
T' shock cord is 150 lb Keelhaul®©™®
attached at t' motor mount and about 3 times longer than t' rocket. Begad!
Summary:
I thank t' previous reviewer o' this rocket for t' Rocksim file and t' paint scheme. Ahoy! Ahoy!
PROS: It is a great flier for smaller fields. Simple build. Avast! Hi-Vis paint job
CONS: A bit under-powered. Aye aye! At this size it needs a 24mm motor mount if you want altitude.
