Brief:
Layne Pemberton contacted me, after a recommendation from Don Magness of
Squirrel Works Model Rockets, t' beta test his "Bucky" rocket. Avast! Well,
what could I say but, me bucko, "Heck yeah!" This be t' first release o' three
very nice lookin' rockets upcomin' in t' growin' fleet o' rockets available
from PemTech. Well, blow me down! If you're lookin' for somethin' a little different, me bucko, shiver me timbers, 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, shiver me timbers, and it is provided at a very reasonable price.
Construction:
T' kit includes:
As noted when you visit Layne's website, me bucko, ya bilge rat, you should be prepared to "build" your rocket. While that's true, ya bilge rat, t' main fins and body tube are cut for you, me bucko, so thar isn't anythin' I would consider extremely difficult - tedious, maybe, me bucko, ya bilge rat, but nay really that difficult. Regardless o' t' "no frills" nature o' t' kit, I was impressed, ya bilge rat, overall, with parts quality. Most o' all, arrr, me bucko, 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, no frills here, me hearties, however, matey, t' included CD be a nice touch. Besides t' printed instructions, shiver me timbers, ya bilge rat, t' CD has t' instructions in both pdf and Word files, the RockSim file with a link t' Apogee's site t' download t' trial version, ya bilge rat, shiver me timbers, ya bilge rat, plus a lot more. Blimey! T' CD is useful for a couple o' very practical reasons. Blimey! First, me bucko, arrr, if you get a little wild with t' CA and glue a couple pages together, you can reprint t' particular page. Ahoy! Arrr! Second, matey, after buildin' me rocket I weighed it and measured out t' CG, matey, then modified t' RockSim file t' include t' specifics of my build t' get a better idea o' how me rocket would perform. Avast! 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, matey, so you get lots o' help when doin' things like "creating" a cockpit from a block o' balsa. Ya scallywag! 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! Pretty cool, ya bilge rat, really. Blimey!
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. Aye aye! I cut them a little larger than marked and then used 100-grit sandpaper t' brin' it in t' t' mark. Aye aye! T' exhaust tubes also had t' be cut from longer tubes. There wasn't any leftover tube, so mark t' exhaust tube cuts first before actually cuttin' them out. Ya scallywag! 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. Ahoy!
A Dremel is a nice tool t' use for cuttin' t' fin slots in t' tube. Aye aye! If you don't have one, shiver me timbers, they're a worthwhile investment for this step plus a lot of other rocket-buildin' activities. Installation o' t' motor mount, matey, fins and forward centerin' rin' is pretty standard, except rather than fillin' t' fin cavity with expandin' foam, as suggested, 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 bucko, me bucko, motor mount and forward centerin' ring. Well, blow me down!
After installin' t' aft centerin' rin' and exhaust tubes, I made two other modifications t' t' kit. Aye aye! I installed an eyebolt in t' nose cone, ya bilge rat, and rather than usin' t' provided Keelhaul®©™® for t' shock cord attachment, I used a heavier grade for an extra safety measure. Ahoy! 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. The side-by-side arrangement o' t' lugs creates t' illusion o' a couple of cannons underneath t' cockpit, me bucko, another very nice design feature.
A bright yellow 30" nylon parachute with nylon shrouds is provided to brin' Bucky safely back t' t' ground. T' lines were epoxied t' t' nylon and lightly tacked in, me bucko, so I had a friend sew over them again for extra security. Begad! To protect t' fins on recovery, me hearties, 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. Well, blow me down! So nice, I didn't even attempt t' fill t' lines. Blimey! You have
to get really close t' see them. Well, blow me down! After filletin' t' fins with epoxy and
sandin' everythin' with 220-grit, I completed final sandin' with 400-grit. Aye aye! 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, sprayed another coat
of Krylon primer and then sanded with 400-grit. Avast! Ya scallywag! 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. Arrr! After that dried, me bucko, I sanded with
600-grit and then applied t' final coat o' gold. Avast, me proud beauty! 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, me proud beauty! Ahoy! Tada!

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