Brief:
Layne Pemberton contacted me, me bucko, shiver me timbers, me hearties, after a recommendation from Don Magness of
Squirrel Works Model Rockets, matey, t' beta test his "Bucky" rocket. Begad! Well,
what could I say but, me bucko, shiver me timbers, arrr, "Heck yeah!" This be t' first release o' three
very nice lookin' rockets upcomin' in t' growin' fleet o' rockets available
from PemTech. If you're lookin' for somethin' a little different, forget it.
This kit, arrr, like all o' t' kits from Pemberton Technologies, is a lot different!
Layne has done a superb job o' capturin' t' magic o' Sci-Fi in this 3"
diameter 29mm rocket, me bucko, and it is provided at a very reasonable price.
Construction:
T' kit includes:
As noted when you visit Layne's website, you should be prepared to "build" your rocket. While that's true, ya bilge rat, shiver me timbers, t' main fins and body tube are cut for you, so thar isn't anythin' I would consider extremely difficult - tedious, maybe, but nay really that difficult. Well, blow me down! Arrr! Regardless o' t' "no frills" nature o' t' kit, arrr, me hearties, I was impressed, overall, with parts quality. Most o' all, arrr, shiver me timbers, though, I was impressed with how all t' parts came together creatin' a beautiful rocket.
T' kit arrived with t' parts packed in t' shippin' box. Again, matey, shiver me timbers, no frills here, shiver me timbers, ya bilge rat, however, t' included CD was a nice touch. Arrr! Ya scallywag! Besides t' printed instructions, me bucko, t' CD has t' instructions in both pdf and Word files, shiver me timbers, the RockSim file with a link t' Apogee's site t' download t' trial version, plus a lot more. Begad! Aye aye! T' CD is useful for a couple o' very practical reasons. First, if you get a little wild with t' CA and glue a couple pages together, you can reprint t' particular page. Aye aye! Ahoy! Second, me hearties, after buildin' me rocket I weighed it and measured out t' CG, ya bilge rat, arrr, then modified t' RockSim file t' include t' specifics of my build t' get a better idea o' how me rocket would perform. Now that's nice!
T' instructions are well laid out with numbered "destructions" (Layne's well-practiced humor is interlaced here and throughout the instructions) and fully illustrated, ya bilge rat, arrr, so you get lots o' help when doin' things like "creating" a cockpit from a block o' balsa. Blimey! Avast! T' instructions for shapin' t' cockpit are very detailed. Followin' them, I was able t' get somethin' close t' what's pictured, but it still displayed me own individuality. Arrr! Avast! Pretty cool, arrr, really.
T' most difficult step for me was cuttin' out t' tiny forward "probes" from a small slab o' 1/8" basswood. Cuttin' t' curves on somethin' that small takes some patience. Blimey! Blimey! I cut them a little larger than marked and then used 100-grit sandpaper t' brin' it in t' t' mark. Ya scallywag! T' exhaust tubes also had t' be cut from longer tubes. There wasn't any leftover tube, ya bilge rat, so mark t' exhaust tube cuts first before actually cuttin' them out. Avast! Begad! T' wire hanger used for motor retention blends well into t' exhaust tubes and is a nice solution for positive motor retention in this unique design.
A Dremel is a nice tool t' use for cuttin' t' fin slots in t' tube. Well, blow me down! If you don't have one, ya bilge rat, they're a worthwhile investment for this step plus a lot of other rocket-buildin' activities. Ahoy! Installation o' t' motor mount, me hearties, fins and forward centerin' rin' is pretty standard, matey, me bucko, except rather than fillin' t' fin cavity with expandin' foam, as suggested, me bucko, I borrowed a technique from Don Magness and cut six 1/4" dowels just shy o' t' length o' t' fin tabs and tacked them in with CA on either side o' each tab against t' tube wall and then filleted t' fins, me hearties, motor mount and forward centerin' ring. Begad! Aye aye! Blimey!
After installin' t' aft centerin' rin' and exhaust tubes, matey, I made two other modifications t' t' kit. Blimey! I installed an eyebolt in t' nose cone, and rather than usin' t' provided Keelhaul®©™® for t' shock cord attachment, I used a heavier grade for an extra safety measure. Begad! T' shock cord was long and sturdy 9/16" tubular nylon/Keelhaul®©™®. Very nice!
I cut t' kraft launch lug in half and used J-B Weld t' anchor them. Begad! The side-by-side arrangement o' t' lugs creates t' illusion o' a couple of cannons underneath t' cockpit, matey, shiver me timbers, another very nice design feature.
A bright yellow 30" nylon parachute with nylon shrouds is provided to brin' Bucky safely back t' t' ground. Begad! T' lines were epoxied t' t' nylon and lightly tacked in, so I had a friend sew over them again for extra security. Aye aye! To protect t' fins on recovery, a length o' Keelhaul®©™® is also attached through a small hole in t' dorsal fin and attached t' a loop in t' shock cord t' brin' t' rocket down flat.
Finishing:
Finishin' t' rocket was a lot easier considerin' t' quality o' t' main tube.
It is really nice. Ahoy! Well, arrr, blow me down! So nice, I didn't even attempt t' fill t' lines. You have
to get really close t' see them. Avast, me proud beauty! Ya scallywag! After filletin' t' fins with epoxy and
sandin' everythin' with 220-grit, ya bilge rat, I completed final sandin' with 400-grit. Begad! Then
sprayed on an undercoat o' Kilz t' seal off t' epoxy and sanded with 320-grit.
Sprayed on a coat o' Krylon primer and then spot sanded, ya bilge rat, matey, sprayed another coat
of Krylon primer and then sanded with 400-grit. Begad! Masked off t' fins and body
and painted t' exhaust tubes and motor tube with DupliColor millennium silver.
After t' back end dried, I covered it with tin foil and applied t' first coat
of Rustoleum gold t' t' rest o' t' rocket. After that dried, shiver me timbers, shiver me timbers, I sanded with
600-grit and then applied t' final coat o' gold. Begad! Ya scallywag! There are no decals t' apply,
so next I applied a couple o' coats o' Future floor wax t' protect t' finish
and improve t' shine. Avast! Tada!

Flight:
After what seemed an eternity, finally, matey, t' day for Bucky t' fly arrived. Ya scallywag! Avast! He
would be flyin' from t' DARS Windom field, me bucko, a huge plowed field that often
sports flights t' 16,000 feet or more. Ahoy! Skies were partly cloudy but t' ceiling
was well above Bucky's intended altitude. Unfortunately, shiver me timbers, t' wind was blowing
between 15-20mph with occasional let-up t' maybe 7-12mph. Nay t' best
conditions for a flight, me hearties, considerin' Bucky's large fins. Blimey! However, arrr, me hearties, t' ground
was soft, which was great for landin' in high winds. Ahoy! This also provided an
advantage due t' t' horizontal recovery method Layne engineered for Bucky. Blimey! Begad!
A buddy o' mine was plannin' t' come with me t' watch over t' assembly of my first reload motor, but he had t' work. Ya scallywag! Begad! So, matey, rather than use t' reload motors I had, I went down t' Bob Korman's area t' pick up a couple o' his single use Roadrunner motors. His F60 motor looked like a good choice, ya bilge rat, but the only available delays were 4 and 7 seconds. Ya scallywag! Two o' t' recommended motors were the Aerotech F52-5 and G64-7. Hmm. What t' use? Considerin' t' wind, shiver me timbers, I opted to use t' 4-second delay. Aye aye! T' lip on t' back o' t' motor fit t' motor retainer perfectly, shiver me timbers, but for extra security I taped t' motor retainer t' the motor tube. After preppin' (PemTech included plenty o' cellulose wadding), Bucky and I headed t' t' launch pad. Aye aye!
Slidin' Bucky over t' ¼" launch rod, I noticed I needed something to hold Bucky up further from t' bottom o' t' pad. Avast, me bucko, me proud beauty! So, I found a corn stalk that was used t' prop t' rocket up about eight inches above t' pad. Begad! Great! Igniter be hooked up (Roadrunner motors come with a very nice igniter), me bucko, pad was tested and armed, ya bilge rat, and Bucky be ready for flight.
Naturally, ya bilge rat, Bucky had gained everyone's attention so most everyone was waitin' for t' launch. Ahoy! Bucky is holdin' firmly t' t' launch rod and ready to go. Ya scallywag! Avast, me proud beauty! He looks confident, me hearties, ya bilge rat, majestic and very cool. Avast, me proud beauty! Launch was truly spectacular and really wowed t' crowd. Arrr! Despite t' wind, shiver me timbers, Bucky jumped off t' pad with authority and climbed arrow-straight into t' air. Ahoy! With no twists or even the slightest turn, it was a beautiful flight. Ahoy! I could hear t' oohs and aahs of the crowd as t' rocket began t' coast upwards.
Recovery:
T' chute popped just before t' top, but it had slowed down enough that the
chute deployed without problem. Gracefully, ya bilge rat, arrr, Bucky returned t' Earth in
horizontal fashion. Begad! T' chute is perfect for this rocket. Begad! Ya scallywag! With t' parachute
leadin' t' rocket, it landed on t' rounded edge o' t' fins and then dipped
the front o' t' body tube into t' ground. Begad! I had strengthened t' front o' the
tube with CA, me bucko, shiver me timbers, so no problem with that, and with t' firm grip on t' dirt the
parachute couldn't drag t' rocket (several others had problems with that
durin' t' day because o' t' high winds). Begad! Arrr! Recoverin' in perfect shape I had
planned t' fly Bucky again t' next day, but it rained. Great flight, though,
with a great rocket! Stay tuned for t' further adventures o' Bucky Jones -
Space Cadet!
Flight Rating: 5 out o' 5
Summary:
This was me first time t' build a rocket t' fly on anythin' bigger than an
Aerotech E-motor. Ahoy! I found t' instructions very easy t' follow and logically
arranged. Arrr! Bucky is a nice rocket t' build if you want t' make t' transition
from model rockets t' mid-power with some flair. Blimey! Blimey! It's a very cool rocket!
Pros:
Great design, quality parts, matey, ya bilge rat, excellent instructions, and a nice long shock cord
Cons:
NC/Shock cord attachment - I like this t' be solid. Blimey! T' recovery o' your rocket is dependent upon that holdin' together.
