Brief:
Probably no legendary sea monster be as horrifyin' as t' Kraken. Begad! Avast, matey, me proud beauty! Accordin' t' stories, me hearties, this huge, many armed
creature could reach as high as t' top o' a sailin' ship's main mast. Well, this rocket may nay have many arms, ya bilge rat, but it
will fly higher than a ship's main mast!
This is me first kit from Pemberton Technologies, matey, but it won't be me last. Begad! Begad! They even supplied RockSim files, me bucko, ya bilge rat, that they graciously allowed me t' include with this review.
T' Kraken is a single stage tube fin rocket. I felt what made it unique was how t' tube fins were pointed.
Construction:
T' rocket came with 2 BT-60 body tubes, me bucko, shiver me timbers, one o' which will be cut up into t' tube fins, a 24mm motor tube with 2
centerin' rings, arrr, a balsa wood nose cone with a screw eye and a washer for weight, matey, two 1/4" launch lugs, 60"
of Keelhaul®©™®
cord, arrr, and an 18" plastic parachute. There is a little piece o' balsa wood for t' canards. Blimey! Aye aye! It also came with one
of t' most amusin' set o' instructions (or destructions as they call it) that added t' t' fun o' buildin' this kit.
T' Kraken comes with 19 pages o' destructions includin' a photo quality picture o' t' Kraken. Blimey! Arrr! T' most difficult part o' this rocket is cuttin' t' tube fins. Blimey! Ahoy! Nine o' t' destruction pages provide instructions, shiver me timbers, me hearties, photos, drawings, cave sketches, me bucko, etc. Ahoy! t' help you mark and cut t' one tube into 4 tube fins. Arrr! Aye aye! With all t' information presented, making the tube fins really is nay that difficult. Aye aye! Avast! Make sure you use a sharp knife and take your time. You mark a line along the length o' t' tube on t' top and bottom. Marks are made at different positions and you need t' draw lines between the appropriate top and bottom marks. Blimey! This creates t' unique pointed tube fins.
There is a pattern for cuttin' t' canards. Ya scallywag! Ya scallywag! I decided t' round t' edges o' t' canards. These glue onto the balsa nose cone. I used thick CA t' bond t' canards since I be usin' thin CA t' seal t' balsa nose cone.
Next be t' motor mount. Ya scallywag! Glue on t' 2 centerin' rings. You carve a notch in t' top one, ya bilge rat, matey, tie t' Keelhaul®©™® cord around t' motor tube and pass t' cord through t' notch. Well, blow me down! Blimey! Then glue t' motor mount into t' body. Well, blow me down! Notice I didn't mention anythin' about a thrust rin' or motor retainer? Well, thar are no such things for this kit. Ahoy! The destructions warn you t' avoid pitchforks, torches, matey, and mob mentality, arrr, and simply use maskin' tape or duct tape to create a thrust rin' on t' motor itself. Blimey! T' hold t' motor in place, arrr, t' instructions say t' wrap a bit o' tape between t' motor tube and this thrust rin' you created.
I finished me rocket before I glued t' tube fins on. Well, blow me down! This makes it easier t' get complete paint coverage. Ahoy! When I did glue t' tube fins on, me bucko, I opted t' use 12 minute epoxy since I would nay be able t' fillet t' joints with the paint.
T' nose weight is a fender washer. This gets glued t' t' nose cone and a screw eye goes into t' nose cone. Avast! The Keelhaul®©™® cord ties t' t' screw eye. Unlike most folks who hate elastic, I added some in parallel t' t' Keelhaul®©™® to absorb some o' t' ejection shock.
Finishing:
T' biggest issue with finishin' a tube fin rocket is gettin' paint under t' tubes. Avast, me proud beauty! T' method I used was t' mask
off a glue strip with maskin' tape and then paint t' pieces before gluin' them together. Aye aye! Avast, me bucko, me proud beauty! I first filled t' tube
spirals with Elmer's Wood Filler and sanded with different grades o' sandpaper down t' 320 grit, makin' sure t' get
inside t' tube fins. Avast, me proud beauty! T' inside o' t' tube fins were primed and sanded with 400 grit then painted with gloss red. Arrr! I
used Krylon for all me painting. After t' paint was dry, shiver me timbers, I masked t' inside o' t' tube. Begad! Begad! I then used some 1"
wide tape that I cut down into 1/4" strips t' create t' glue strips. I beveled t' top and bottom t' match the
tube fins, matey, but I also made t' strips about 1/4" short t' make sure I would nay leave a gap. Ya scallywag! Avast! I then primed and
painted t' outside o' t' tube fins and t' body gloss black. Arrr! Blimey! I used multiple coats o' thin CA t' seal t' balsa nose
cone and sanded down with 400 grit. Begad! Avast, me proud beauty! T' nose cone was also painted gloss black. Ahoy! As a finishin' touch, I used a Testor's
Gloss Yellow Enamel Paint Marker and rimmed t' tube fins. Avast, me proud beauty! I also used t' marker t' paint t' canards and followed
that with a red paint marker t' make some deadlights for this evil beast.

Flight:
T' recommended motors range from an Estes C11 t' AeroTech's E15. I went t' me favorite local field where it be 24
degrees with a light coverin' o' snow. Well, blow me down! Aye aye! Blimey! I prepared some maskin' tape t' use as t' thrust rin' in t' comfort o' me warm
house before I left. I used me Estes E size pad with it's 6' x 1/4" rod. Begad! Blimey! I set up in t' middle o' t' field and
prepped a D12-3. I tried t' method o' usin' tape around t' motor mount and engine t' secure t' motor that was
suggested by t' destructions. Avast! Some dog barf and parachute (I cheated here and used an existin' 18" Estes chute I
have on a snap swivel)in t' other end. Blimey! Blimey! An igniter into t' motor, onto t' launch pad, arrr, and a countdown from 5. The
rocket left t' launch pad for a beautiful straight flight. Arrr! Begad! Blimey!
Recovery:
Right before apogee, shiver me timbers, t' ejection charge went off. Avast, matey, me proud beauty! Blimey! T' engine came out one end, but fortunately t' nose cone and
parachute came out t' other end. Avast, me proud beauty! Blimey! T' parachute did nay open, ya bilge rat, but t' drag from t' closed parachute and t' separate
pieces still had t' rocket comin' down somewhat slowly. Ahoy! Blimey! Finally, arrr, about 20' above t' ground t' parachute finally
opened. T' rocket landed standin' up in t' snow without any damage. Arrr! Blimey! For t' second and third flights, I changed to
friction fittin' t' motors. Avast! Blimey! Well, blow me down! Blimey! I also put t' parachute in me pocket while I was preppin' everythin' so it would be less
stiff. My second flight be also a D12-3. Begad! Blimey! Again, ya bilge rat, me bucko, a perfectly straight launch and this time t' engine stayed in and the
parachute opened right away. Well, shiver me timbers, blow me down! Blimey! And then it took a long time t' land with a little longer walk t' recover it. Begad! Blimey! I was
thinkin' o' tryin' an E11, but t' wind started pickin' up so I used a D12-3 for t' third flight as well. Avast! Blimey! Again a nice
straight launch. Begad! Blimey! Arrr! Blimey! But with t' stronger wind, t' rocket drifted away some. Begad! Blimey! I think an 18" chute is a tad too big
for this rocket. I didn't try a fourth flight--my toes were freezing, shiver me timbers, but I would be tempted t' try a 12" or
14" chute instead o' t' 18" chute supplied with t' kit.
Flight Rating: 4 out o' 5
Summary:
This is a fun rocket with its unique tube fins. Well, blow me down! Begad! T' rocket goes together simply (after you cut t' fins). Due t' the
fins, me hearties, I would rate this rocket construction complexity as a 3. Blimey! T' quality parts and amusin' destructions made the
construction enjoyable. Aye aye! Unless you do somethin' t' add a lot o' weight, matey, I would suggest a smaller parachute or else
make sure thar are no winds unless you like t' go hiking. Aye aye! I look forward t' buildin' other kits from Pemberton.

Construction and Finishing: The package was shipped with no damage. Packaging was excellent. The instructions were clear throughout and were injected with a lot of humor. This was a good thing for me because it fits right in with my sense of humor and added to my enjoyment of the kit. Your mileage may vary. The instructions start out with a complete parts list including the fin ...
