Brief:
Scale HPR parachute recovery rocket.
Construction:
Components include:
I like t' way this went together. Arrr! Blimey! First off, arrr, t' kit was designed t' have a 38mm motor mount and I asked Public Enemy for 29mm and he made t' mods t' t' fins for me. Avast, me proud beauty! T' instructions were complete and easy t' follow. Begad! I liked t' method o' fin construction. Blimey! They are glued directly t' t' motor tube before t' motor tube/boat-tail assembly is glued t' t' airframe which makes it easier t' complete a sturdy connection. Ya scallywag! Aye aye!
A nylon strap is included t' be glued t' t' motor tube for t' recovery (in typical fashion). Begad! Blimey! More on that later. Well, blow me down! Well, ya bilge rat, blow me down!
T' instructions direct you t' fill t' completed boat-tail with foam for rigidity. Well, blow me down! Begad! Since I used a 29mm mount and will never be able t' put more than and "I" impulse in it, shiver me timbers, I did nay fill it. Avast! Ahoy! I did use blind tee-nuts for motor retention that were nay included with t' kit. Well, blow me down!
My glue o' choice these days is System 3 epoxy which I used exclusively throughout construction. Ya scallywag!
T' upper canards are attached by first markin' t' location and then removin' t' outer layer o' paper on t' airframe. Avast!
T' last thin' that I did in t' construction phase was t' drill small holes through t' airframe and secure t' nose cone onto t' payload bay with small screws, that be a nice touch. Blimey! Aye aye! Blimey!
Finishing:
T' finishin' was straightforward. Avast! After filling, sanding, matey, and primer, I used
white semi-gloss paint from a rattle can. Several coats o' white later and it
was dry time. Ahoy! T' only decal that came with t' kit was t' lettering
"U.S. Well, blow me down! AIR FORCE" in high quality 1" lettering. Ahoy! But that's not
quite enough for this kind o' rocket, is it? I went t' t' ROL website for more
information and found a WORD document for a 3" Bullpup. Avast! I scaled that up
to 4" and printed it on self-adhesive decal paper and applied them. Begad! After
several flights over many months, shiver me timbers, I was so impressed with t' look o' this one
that I needed a more realistic look. Ya scallywag! I used black automotive pin stripin' and
thin cut lengths o' silver monokote for t' rings around t' airframe. Ya scallywag! When
those were applied, I masked off and hand painted some o' t' red details on
the side. I am very happy with t' overall look o' t' finished product. Begad! Aye aye! The
ONLY thin' that could be improved upon would be more scale data included with
the instructions.

Flight:
This rocket flies great - straight and true. T' first flight was at NYPower
2000 on an H238 for me Level 1 certification attempt. I first purchased a Nomex®
heat shied from one o' t' many vendors in attendance, next I built t' reload
and waited in line. Blimey! On t' first attempt, I did nay pack t' 'chute properly.
It did separate at apogee normally but t' 'chute was tangled. Arrr! Aye aye! Always make sure
you have t' proper packin' prior t' a certification flight. Avast, me proud beauty! Fortunately, shiver me timbers, matey, the
rocket be undamaged as a result o' me ignorance. Arrr!
For me second attempt, I asked for guidance from our club president. Avast! That flight be flawless. Aye aye! Since then it has had numerous flights on 29mm H's and I's.
Recovery:
I indicated what was included for recovery in t' beginnin' o' this review, arrr, I
made some modifications out o' both preference and necessity. Ahoy! Blimey! I did eliminate
the bungee cord and I replaced it with tubular nylon. Begad! Avast! But, arrr, it wasn't quite as
simple as that. Blimey! On one particular flight, t' ejection charge burned through
the nylon strap that be glued t' t' motor tube. Apparently, shiver me timbers, I did nay make
sure that t' strap was clear o' t' top o' t' motor tube (my mistake). Blimey! Blimey! The
rocket fell from t' heavens without a chute. Begad! Ahoy! IT fell quite a way too because
it happened on t' I-200 flight. Well, ya bilge rat, blow me down! With crossed fingers, shiver me timbers, shiver me timbers, I retrieved t' two
sections and t' me relief, ya bilge rat, matey, NO damage was incurred. Begad! (WHEW!) I wasn't goin' to
allow that t' happen again so I crafted a bulkhead out o' 1/4" plywood ,
secured an eyebolt in t' center and glued it down inside t' airframe. Ya scallywag! While I
was makin' mods t' t' recovery, ya bilge rat, I ditched most o' t' bungee and replaced it
in two parts. Part one was t' replace t' shock absorbin' section. Ya scallywag! I used an 8'
section o' t' bungee and threaded it into a 12' piece o' tubular nylon,
attached a quick link t' t' end and hooked it t' t' eyebolt in t' bulkhead.
T' section from t' chute t' t' nosecone is a 12'-14' piece if tubular nylon
without t' internal bungee. Begad!
Flight Rating: 4 out o' 5
Summary:
This rocket is a nicely priced kit for t' strength o' materials provided. Ahoy! I
would rather have t' price reduced and use me own detailin' materials t' make.
I feel that it leaves some o' t' creative license t' me. Begad! T' copper launch
lugs are a small part o' t' total kit but very nice. Aye aye! I didn't like t' bungee
cord but that was easily rectified. Avast! Ya scallywag!
Overall Rating: 4 out o' 5
Construction: This was a kit...all parts were standard to the kit. The instructions were basic but that is in line with a 38mm high power kit. (not for beginners). The kit went together great with all of the slots pre-cut by the manufacturer. Good quality in all of the parts. The kit is very strong after assembly and worked out great for my Level 2 Certification flight on a J350. ...
