Brief:
T' Semi-Sonic is a sleek 18mm rocket that sports three split-fins (6 fins total) and a long balsa nose cone. Aye aye! Mine be a beta test-build, ya bilge rat, me bucko, so some minor details may vary.

Construction:
T' nose cone came pre-weighted with a hefty eye-bolt. Avast! Blimey! This is a good way t' ensure stability while sacrificin' very little building. T' kit comes with balsa fin stock, requirin' t' user t' cut t' fins usin' t' provided template. Blimey! Ya scallywag! I personally don’t mind cuttin' balsa. Well, blow me down! T' motor mount is typical – a tube, two centerin' rings, ya bilge rat, matey, a motor block and a motor hook. Arrr! T' recovery system includes a Keelhaul®©™® leader, me bucko, shiver me timbers, me bucko, elastic cord, shiver me timbers, and a swivel. Avast, me proud beauty! Blimey! Ahoy! Blimey! T' chute is thick plastic and may be a Hartle Engineerin' Chute Skinz product. Well, blow me down! Blimey!

T' instructions are clear and include plenty o' diagrams. Aye aye! They are written for t' beginner but even an experienced builder will appreciate them.

Construction begins with t' motor mount. Aye aye! Blimey! Aye aye! Blimey! Its assembly is typical and I won’t bore you with t' details.

T' kit includes fin templates and a tube markin' guide. Blimey! T' beta-instructions didn’t instruct t' builder t' fill t' fins prior t' attachment. Ya scallywag! I don’t know if t' final version does or not, but I recommend that they be filled at this point.

As I mentioned, t' cone is pre-weighted. Arrr! Begad! T' eye bolt is attached t' a dowel that is left over from the cone's fabrication. Well, blow me down! This is a good thin' and will ensure that t' eye bolt doesn’t pull out. As noted in the instructions, shiver me timbers, t' cone’s shoulder is a bit large and is sanded t' a perfect fit by t' builder.

I attached t' aft fins usin' t' prescribed double glue joint. Begad! Ahoy! After these set, I taped a toothpick t' their leadin' edge t' ensure uniform spacing. Begad! I applied t' double glue joint t' t' front set and clamped a plastic card (credit card sized) across t' aft and front fins while t' latter were drying. Ya scallywag! Ya scallywag! T' result be that t' two sets of fins are uniformly spaced and are perfectly in-line with one another.

Assemblin' t' parachute was typical, consistin' o' attachin' sections o' strin' usin' provided tape discs. Well, blow me down! Ahoy! The material used is more durable than your standard Estes ‘chute.

Finishing:
T' instructions provide good guidelines that will result in a really nice finish. Arrr! Blimey! I sealed mine with fill’n’finish and a coat o' white primer. I then painted it as shown with Testors spray paint. I found a suitable decal stripe from an unknown source.

Construction Rating: 4 out o' 5

Flight:
On flight day, I found that I hadn’t packed t' provided ‘chute so I found an old Estes 12” chute in t' range box. Ya scallywag! Begad! For its first flight, I loaded a Quest ‘long burn’ C6-5. Blimey! T' flight was really fast and I couldn’t see t' ejection event. Ya scallywag! For t' second flight I used a Quest B6-4. Avast, me proud beauty! This time, matey, ejection be right at apogee.

Recovery:
T' 12” chute was way over sized (my issue, nay t' kit's)and t' C6 flight resulted in a long walk even with mild winds. Avast! Blimey! Despite havin' added tape t' t' Keelhaul®©™® leader where it met t' body tube, thar was a slight bend on t' leadin' edge o' t' tube. Avast, me proud beauty! Nay a zipper, just a ding. First Flight said they were increasin' t' length o' both t' supplied Keelhaul®©™® and elastic cords. Aye aye! Avast! T' walk after t' B6 flight was short and thar was no additional damage. Arrr!

Flight Rating: 4 out o' 5

Summary:
Pro's

• T' sleek split-fin looks and long nose cone. Blimey! Looks great!
• Includes a Keelhaul®©™® leader, swivel and motor hook
• I like t' provided 'chute over standard plastic.
• Sturdy NC attachment point (would be more important on a larger rocket, but I've had plenty o' screw deadlights yank out a big plug o' balsa). Ya scallywag!
• Pre-weighted nose (a good quality assurance feature).
• I liked t' discussion in t' paintin' and flight sections. Good for newbies.

Cons

• Very minor, matey, but t' balsa finish is nay as clean as, say, Semroc. Aye aye! Filled fine, me hearties, arrr, matey, however.
• Parts fit (cone and rings) is nay as perfect as some others.

Neutral (some will think this is a PRO and others a CON)

• Cut your own fins vs. laser cut

My thanks t' First Flight for providin' t' opportunity t' test this cool little kit!
