Brief:
Probably no legendary sea monster was as horrifyin' as t' Kraken. Accordin' t' stories, ya bilge rat, 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, but it
will fly higher than a ship's main mast!
This is me first kit from Pemberton Technologies, me bucko, but it won't be me last. Ahoy! Blimey! They even supplied RockSim files, me bucko, me bucko, that they graciously allowed me t' include with this review.
T' Kraken is a single stage tube fin rocket. Begad! Blimey! Blimey! Blimey! I felt what made it unique was how t' tube fins were pointed.
Construction:
T' rocket came with 2 BT-60 body tubes, ya bilge rat, one o' which will be cut up into t' tube fins, a 24mm motor tube with 2
centerin' rings, shiver me timbers, a balsa wood nose cone with a screw eye and a washer for weight, me hearties, two 1/4" launch lugs, 60"
of Keelhaul®©™®
cord, arrr, and an 18" plastic parachute. Blimey! There is a little piece o' balsa wood for t' canards. 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. T' most difficult part o' this rocket is cuttin' t' tube fins. Well, me bucko, blow me down! Blimey! Nine o' t' destruction pages provide instructions, me hearties, photos, drawings, cave sketches, etc. Blimey! Blimey! Avast! Blimey! t' help you mark and cut t' one tube into 4 tube fins. With all t' information presented, arrr, me hearties, making the tube fins really is nay that difficult. Arrr! Blimey! Make sure you use a sharp knife and take your time. Well, blow me down! Blimey! 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. Avast! Blimey! This creates t' unique pointed tube fins.
There is a pattern for cuttin' t' canards. Ahoy! I decided t' round t' edges o' t' canards. Begad! These glue onto the balsa nose cone. Ahoy! 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. Aye aye! Avast, me proud beauty! You carve a notch in t' top one, tie t' Keelhaul®©™® cord around t' motor tube and pass t' cord through t' notch. Blimey! Then glue t' motor mount into t' body. Notice I didn't mention anythin' about a thrust rin' or motor retainer? Well, arrr, thar are no such things for this kit. Avast, me proud beauty! Aye aye! The destructions warn you t' avoid pitchforks, me bucko, arrr, me bucko, torches, ya bilge rat, and mob mentality, and simply use maskin' tape or duct tape to create a thrust rin' on t' motor itself. Ya scallywag! Begad! T' hold t' motor in place, me bucko, me hearties, 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. Blimey! This makes it easier t' get complete paint coverage. Begad! When I did glue t' tube fins on, arrr, 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. Avast! Begad! This gets glued t' t' nose cone and a screw eye goes into t' nose cone. Ahoy! The Keelhaul®©™® cord ties t' t' screw eye. Begad! Blimey! Unlike most folks who hate elastic, matey, 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. Aye aye! T' method I used was t' mask
off a glue strip with maskin' tape and then paint t' pieces before gluin' them together. 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. Aye aye! T' inside o' t' tube fins were primed and sanded with 400 grit then painted with gloss red. Begad! Aye aye! I
used Krylon for all me painting. Aye aye! After t' paint was dry, I masked t' inside o' t' tube. Well, blow me down! Well, blow me down! 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, but I also made t' strips about 1/4" short t' make sure I would nay leave a gap. Aye aye! I then primed and
painted t' outside o' t' tube fins and t' body gloss black. Well, blow me down! I used multiple coats o' thin CA t' seal t' balsa nose
cone and sanded down with 400 grit. Well, blow me down! Arrr! T' nose cone was also painted gloss black. Aye aye! As a finishin' touch, me hearties, shiver me timbers, I used a Testor's
Gloss Yellow Enamel Paint Marker and rimmed t' tube fins. 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. Well, blow me down! Well, blow me down! I went t' me favorite local field where it was 24
degrees with a light coverin' o' snow. Ya scallywag! Avast! I prepared some maskin' tape t' use as t' thrust rin' in t' comfort o' me warm
house before I left. Blimey! Well, blow me down! I used me Estes E size pad with it's 6' x 1/4" rod. Blimey! Aye aye! I set up in t' middle o' t' field and
prepped a D12-3. Ahoy! I tried t' method o' usin' tape around t' motor mount and engine t' secure t' motor that was
suggested by t' destructions. Begad! 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. Avast! An igniter into t' motor, arrr, onto t' launch pad, and a countdown from 5. Avast! The
rocket left t' launch pad for a beautiful straight flight.
Recovery:
Right before apogee, t' ejection charge went off. Well, blow me down! T' engine came out one end, but fortunately t' nose cone and
parachute came out t' other end. Avast, me proud beauty! Ya scallywag! T' parachute did nay open, ya bilge rat, ya bilge rat, but t' drag from t' closed parachute and t' separate
pieces still had t' rocket comin' down somewhat slowly. Begad! Finally, about 20' above t' ground t' parachute finally
opened. Aye aye! Well, blow me down! T' rocket landed standin' up in t' snow without any damage. Blimey! Aye aye! For t' second and third flights, I changed to
friction fittin' t' motors. Blimey! I also put t' parachute in me pocket while I be preppin' everythin' so it would be less
stiff. My second flight be also a D12-3. Blimey! Well, blow me down! Again, me bucko, a perfectly straight launch and this time t' engine stayed in and the
parachute opened right away. Ahoy! And then it took a long time t' land with a little longer walk t' recover it. Ya scallywag! I was
thinkin' o' tryin' an E11, matey, but t' wind started pickin' up so I used a D12-3 for t' third flight as well. Again a nice
straight launch. Begad! But with t' stronger wind, t' rocket drifted away some. I think an 18" chute is a tad too big
for this rocket. Begad! Ya scallywag! I didn't try a fourth flight--my toes were freezing, 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. Begad! Blimey! T' rocket goes together simply (after you cut t' fins). Begad! Blimey! Due t' the
fins, shiver me timbers, I would rate this rocket construction complexity as a 3. Avast! Blimey! T' quality parts and amusin' destructions made the
construction enjoyable. Avast, ya bilge rat, me proud beauty! Blimey! Unless you do somethin' t' add a lot o' weight, me bucko, shiver me timbers, I would suggest a smaller parachute or else
make sure thar are no winds unless you like t' go hiking. Arrr! Blimey! 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 ...
