Materials:
All parts were accounted for, matey, except for a Yank Enterprises decal, matey, which was advertised but nay included. Ahoy! As this was a scale rocket, ya bilge rat, I had no intention of usin' it anyway, so this was no loss. Blimey! Aye aye! T' kit consisted o' 2 lengths o' 3" flexible phenolic body tube (34" & 31" long), ya bilge rat, one o' them slotted for t' aft fins. Ya scallywag! T' forward BT be supposed t' be marked for t' forward fins per t' included instructions, shiver me timbers, shiver me timbers, but was nay (no big deal, arrr, as it's nay that difficult t' make a fin guide with any graphics program). Ya scallywag! Also included were 1 30" ripstop nylon parachute, ya bilge rat, 20 feet o' 9/16" tubular nylon, 2 quick-links, 2 eyebolts w/ washers, matey, tube coupler, one birch ply bulkhead, arrr, 2 baltic birch ply centerin' rings, ya bilge rat, a 38mm motor mount, ogive nose cone, me bucko, and 8 1/8" 5-ply baltic birch fins. Aye aye! A couple o' t' aft fins were slightly warped, but I attribute this t' t' kit probably sittin' in t' hobby store basement for a considerable amount o' time, shiver me timbers, me hearties, arrr, as t' maskin' tape also left marks that no amount o' sandin' would remove. All parts were very high quality and fit well together, ya bilge rat, me bucko, although with an assembled weight o' 60 oz, ya bilge rat, I thought 3/16" or 1/4" ply would have been more appropriate for t' aft fins, as they sweep back past t' aft end o' t' rocket.

Materials score: 4 out o' 5
Pros: Very sturdy BTs and nice hardware
Cons: Aft fins are a little thin and t' parachute might be a size small (the website says they now ship 36" chutes) for t' weight o' t' rocket. Ya scallywag!

Construction:
Instructions were thorough if small, matey, with one exception. Ahoy! Avast, me proud beauty! They did nay specify at t' appropriate step exactly how far forward from t' BT junction t' put the forward fins. I guessed at 1" and after lookin' at t' scale finishing directions, I believe this t' be correct. Ahoy! I decided t' go with an anti-zipper design as detailed in InfoCentral on Rocketry Online, me bucko, which changed my construction considerably from t' directions.

I drilled eight 5/16" holes in t' bulkhead, me bucko, arrr, which be pre-drilled for the eyebolt assembly. I attached t' eyebolt assembly (washers were included) and epoxied it into t' coupler tube with a heavy fillet around t' outside. Aye aye!

T' forward BT needed t' be slotted, and took a bit o' time, me hearties, shiver me timbers, me hearties, as thar are a lot o' layers t' cut and peel. Avast, me proud beauty! Begad! Since I would be cementin' t' coupler t' the lower BT instead o' t' upper, I cut t' slots a touch short and pushed the fins through t' back in order t' get a very tight fit before runnin' fillets along t' outside joints with 30 min epoxy.

On t' t' motor mount. Ahoy! After cementin' t' forward centerin' rin' 1/4" from t' front o' t' MMT as directed and cementin' it t' t' BT, I realized that I should have gotten a 3rd centerin' rin' t' add right in front o' the fins. Arrr! Arrr! T' instructions said t' cement t' aft centerin' rin' immediately and to simply run a bead o' epoxy t' t' fin root in order t' affix t' fins t' the MMT. Arrr! I chose t' run fillets instead and held off on cementin' t' aft centering rin' until that was done. Arrr! Begad! Since I didn't have a CR at t' front o' t' fins to serve as a dam for t' forward end o' t' fillets, matey, I used 5 min epoxy for the internal fillets. Aye aye! Ya scallywag! I then used 1.5 oz glass t' reinforce t' fins and ran some very heavy outside fillets usin' 30 min. Blimey! epoxy. Ya scallywag! Well, shiver me timbers, blow me down!

After puttin' blind T-nuts in for retention, arrr, I saw that I didn't have a whole lot o' room t' fillet t' aft centerin' rin' t' both t' MMT and the outer BT, so I decided t' just go with an epoxy well. Avast! T' protect t' T-nut opening, matey, ya bilge rat, instead o' usin' tape and redrillin' through t' epoxy, I cut some plastic drinkin' straws down t' size, fitted them over t' mountin' screws and screwed them down until t' straws were snug against t' threads. Once the epoxy set, it be easy t' simply pull t' straws out, leavin' a hole for the mountin' screws. Arrr!

Then, me bucko, I cemented t' coupler t' t' aft BT with t' bulkhead facin' forward. Since I was usin' t' nosecone for t' forward end o' t' shock cord, arrr, I covered the other eyebolt with epoxy and inserted it into t' hole in t' bottom o' the NC. Avast! I then cut a hole in t' shoulder o' t' NC and used a syringe t' insert an epoxy well, matey, which I hoped would ensure that t' eyebolt stayed in place. Begad!

Now, ya bilge rat, me hearties, this kit has a very interestin' method for attachin' your shock cord to the eyebolt. Begad! Begad! T' instructions recommend loopin' t' cord through t' eyebolt and back onto itself (I did this on t' nosecone end). Then, approximately 4" o' overlap is completely saturated with 30 min epoxy and wrapped with tape. Avast, me proud beauty! I chose electrical tape for this process and it comes out very strong. Another loop at t' other end is completed and will be hooked onto a quicklink at t' other end. Since I wasn't goin' t' be modifyin' this kit any further, arrr, I sanded t' nosecone shoulder and epoxied it t' t' top o' t' rocket. Begad! Aye aye! A quicklink on t' bulkhead eyebolt and on t' parachute complete t' recovery harness. Arrr! Blimey! Rail buttons were substituted for t' enclosed launch lugs, as I was told it's easier t' get a rail than t' right size rod at a launch. Arrr!

Construction score: 4 out o' 5
Pros: Everythin' fits well together.
Cons: Slottin' flexible phenolic with a hobby knife isn't me idea o' fun. Blimey!

Finishing:
I had filled t' spirals with cheap spackle prior t' construction, so all that was needed at this point be several layers o' gray Krylon primer t' fill in what t' spackle missed and a coat o' white Krylon primer on top t' guard against colors darkening. Begad! Due t' t' thickness o' t' flexible phenolic BT, there was a little additional fillin' t' be done from t' top o' t' BT t' the nose cone prior t' priming. Blimey! Avast, me proud beauty! All o' this be easily accomplished, and t' primer took readily t' all sanded surfaces. Krylon paint was then used throughout for a scale paint job that drew several compliments at t' launch site. Gotta love Krylon! You really have t' work at it t' make that stuff run. Avast! Blimey!

Finishin' score: 5 out o' 5
Pros: T' scale paint scheme is really neat and is a crowd-pleaser.
Cons: Slight fillin' needed betwixt t' nosecone and t' body tube. Well, blow me down! Arrr!

Flight:
T' model weighed in at t' launch almost exactly at 60 oz. dry, even with the 45" chute that I substituted for t' 30" enclosed chute and a Transolve TransBeep as well. Arrr! Begad! Well, this be me Level 1 certification flight on an H242T, as well as me first "real" project beyond Aerotech, matey, so needless t' say I had plenty o' nerves here. Avast! Begad! There was a slight wind (maybe 5 mph) which seemed t' be slightly affectin' most o' t' flights that morning. Since t' anti-zipper design caused about 4 margins o' stability with t' motor loaded, me bucko, I decided t' launch vertically t' minimize weathercockin' instead of savin' myself a walk. Ahoy! Ahoy! When t' button be pressed, me bucko, t' rocket went perfectly vertical, with zero weathercocking. Deployment was perfectly at apogee on a 10 second delay. Ahoy! Ahoy! RockSim said this would be at about 1700 feet at this weight and with t' modifications, me bucko, but it honestly looked higher than that. Begad! Since I be a little paranoid about t' drag separation and deployment, I placed t' chute about 6 feet from t' aft part o' t' rocket, which I think may have been a mistake. I suffered some minor fin damage, which, matey, I now believe may have been due t' t' front end o' t' rocket hittin' t' fin durin' deployment. All told, it was a fantastic flight, shiver me timbers, and be good for me level 1. Avast!

Pros: Straight as an arrow in t' slight wind
Cons: Can't really think o' any.

Flight Rating: 5 out o' 5

Summary:
This thin' builds like a tank, despite bein' as long as it is. Well, blow me down! Blimey! Flies beautifully on t' 242 and I can't wait t' up it a touch t' t' I357. This is a great certification kit, shiver me timbers, matey, despite its length, ya bilge rat, as it's tough as nails with a little fin reinforcement. Blimey! Ahoy! Had I nay cemented t' nose cone in, I would wager that it could be modified for dual deployment and easily stand up t' a level 2 flight as well. Ya scallywag!
