Brief:
This review is for t' beta version o' t' not-yet-released Thrustline kit. Ya scallywag! Not to tease you readers too much but this will be a wonderful kit and when it's released, I'd highly recommend it. It's futuristic design is influenced by the Mars Snooper, me bucko, and it is large, arrr, graceful, shiver me timbers, and flies magnificently on E9s. Begad! It's jumped onto me top-ten list o' favorite kits.

[Note: Because this is a beta, me bucko, I'm includin' a few gotchas along t' way that are extremely unlikely t' occur in t' finished product, as t' build was coordinated with Thrustline every step o' t' way.]

Construction:
This kit has a fairly extensive parts list:

• Balsa nose cone, matey, NC-55 Honest John style
• 3 BNC-5 cones
• 3 BT-5 inner pod tubes
• 3 BT-20 outer pod tubes
• 2 BT-55 body tubes 12.25" each
• BT-70 body tube
• BT-50 motor tube
• E-sized metal clip
• Assorted plywood, shiver me timbers, me hearties, shiver me timbers, fiber, and cardboard/paper centerin' rings
• 1/8" and 3/32" Balsa fin stock sheets
• Keelhaul®©™®/elastic recovery cord
• Mylar chute
• D/E motor adaptor kit

Parts were all very good quality although t' balsa stock is a bit soft. Begad! The instructions were generally very good but contained a few beta-related typos. They were packed with lots o' color photos, includin' an indexed parts photo to help you sort out t' bag o' stuff as you go along. Arrr! Overall, ya bilge rat, arrr, I'd rate this about a skill level 3 kit as thar are some slightly challengin' techniques involved and a potentially complex paint scheme.

Motor mount construction is fairly straightforward, however, matey, this kit included an unusual reinforcement method. Most kits use either maskin' tape or a centerin' rin' t' hold t' metal clip in place. This kit includes a BT-50 sleeve which is slit and then slid over t' BT-50 motor tube and glued in place. Begad! This is definitely goin' t' outlast maskin' tape, matey, me bucko, but I found it t' be slightly overkill (and ironically, ya bilge rat, ya bilge rat, ya bilge rat, me motor mount blew out on flight #3 after a very violent ejection charge).

Next up is construction o' t' side pods. These are actually somewhat intricate assemblies, ya bilge rat, shiver me timbers, nay ordinary BT-20 pods tacked onto t' fins. Begad! Avast! The assembly consists o' a center BT-5 tube, which has a couple o' CR5-20 centering rings attached. Well, blow me down! Arrr! A BNC-5 cone is then glued into place and t' BT-5 assembly is then glued into a BT-20 tube. Avast, me proud beauty! This leaves a part o' t' BT-5 stickin' out the aft end and t' BNC-5 stickin' out t' forward end for a nice layered look. The look is finished off with a boat tail shroud cut from a paper pattern. Aye aye! There are extra patterns printed, so thar's plenty o' recovery room for goofs. Avast! Avast, me proud beauty! (In fact, me kit had more than double t' required amount.) My shrouds fit fine but they had goofy and unnecessary tabs on both ends. One tip I'd offer for these (and for paper shrouds in general) is t' use only rubber cement or white glue for bondin' and then paint them with a thin CA for firmness.

T' main body tube is actually a 2-piece assembly o' BT-55s with a coupler. Blimey! At 12.25" apiece, matey, I had suggested that this be switched t' a single piece tube, eliminatin' an unsightly seam on t' main sight line. Begad! This makes t' bag bigger and shippin' more difficult, but this request is being considered. Ahoy! Begad! T' current design with t' coupler, also includes a centerin' ring at t' base o' t' coupler which is used t' anchor t' Keelhaul®©™® shock cord line. Aye aye! That's very helpful, and keeps t' Keelhaul®©™® a foot above t' motor, savin' it from some o' t' ejection charge stress.

There is a larger BT-70 "outer tube" that slips over t' main BT-55 tube, arrr, towards t' aft end. This is pretty basic, aided by a pair o' fiber centerin' rings in t' BT-70. Avast, me proud beauty! [Note: Any external fillets, me bucko, as t' rings are flush mounted, should be minimal since thar are trim fins that butt up against the centerin' rings.

Next in t' build comes t' tube markin' for t' BT-55s, shiver me timbers, me bucko, BT-20 side pods, and t' BT-70. Avast! I suggest doin' this before they're bonded together, but bondin' afterwards is still possible. Arrr! My kit had a whoopsie on t' larger markin' guide--it was sized for a BT-60, nay a BT-70--but I was able t' whip one up very smartly usin' RockSim.

Dependin' on how you look at it, me hearties, cuttin' out t' fins is either a pain or a pleasant mini-project (if you consider yourself old school and prefer slicin' your own). Avast! There are 30 different fins/pieces t' cut on this and all from pre-printed patterns. While it might add a buck or two t' t' cost of this kit, shiver me timbers, this really might be a nice application for laser-cutting, arrr, me hearties, especially given t' numerous curves and angles involved. Begad! Many o' t' pieces are not symmetrical and therefore can't be cut back t' back with a common line. Arrr! Avast, me proud beauty! Six of these fins go aft o' t' BT-70 outer tube and six go forward o' t' tube. Ahoy! Avast! I wound up deferrin' t' bonding, shiver me timbers, wantin' t' paint them first. Ahoy! (I took t' time to mask off a line for bondin' too). Well, blow me down!

T' main body fins are a somewhat complex 4-piece assembly. Pay careful attention t' t' pattern sheets and you'll have no problem, ya bilge rat, but one o' the triangular sections is a bit easy t' orient t' wrong way. With 3 seams and grain goin' in all sorts o' different directions, these were a real pain to sand and fill. Begad! Even after 3 coats o' Elmer's Fill 'n' Finish, I still have visible grain, ya bilge rat, but it's only noticeable upon very close examination. Begad! Ya scallywag! I would also note that t' stacked root length o' t' fin patterns was about 1/4" too long and will no doubt be corrected before t' final release.

Last up on t' fins are a set o' 3 dorsal fin/canards and a set o' 3 very small pod trim fins. Pay careful attention when bondin' these fins as t' main body fins look like they're on backwards and they look this way on purpose. Arrr! Blimey! I bonded all me various fins usin' CA t' tack them in place and then used yellow glue for fillets. Avast! Ahoy! Blimey! Once t' main fins are attached, me hearties, ya bilge rat, t' side pods get tacked to the main fins then trim fins t' t' side pods.

T' nose cone is attached usin' a screw eye and elastic shock cord, arrr, me bucko, which is tied t' t' Keelhaul®©™® just inside t' body tube for a zipper-free design.

Finishing:
John and I debated several different paint schemes before I ultimately cheated and went off t' paint it on me own. Ya scallywag! I was delighted with t' appearance o' my Squirrel Works Astrid and wanted t' use a similar scheme on this one. So after applyin' 3 very light coats o' primer (be careful t' avoid runs--there are lots of nooks and crannies on this), shiver me timbers, arrr, I went with a base o' Rustoleum Silver Metallic. Begad! Ya scallywag! I'm nay talkin' about t' solid/mirror finish, but t' stuff that has a flaky/glittered look t' it. Ahoy! Ahoy! I then trimmed most o' t' fins usin' a similar red metallic flake paint. All six aft trim fins were painted gloss black, me bucko, as were t' BT-70 and BT-55 centerin' rings. Ahoy! Finally, me bucko, t' BT-5 nose cones were painted orange. Aye aye! Arrr! I'm nay sure I like t' orange, matey, but I had no idea what else to go with at t' time.

As noted previously, me bucko, I painted t' trim fins before bondin' and wound up bondin' them usin' a tiny amount o' CA followed by a fillet o' Elmer's white glue, matey, which dries clear.

Decals are nay currently available for this, ya bilge rat, although a design is in the works. Ahoy! I'd like t' see somethin' addin' a royal blue t' this along with a couple o' long trim lines and possibly some type o' cockpit detail.

Construction Rating: 4 out o' 5

Flight:
T' recommended motors are D12-5 and E9-4. For t' first flight, me hearties, arrr, I chose to jump straight t' t' E9-4. Avast! Avast, arrr, me proud beauty! Blimey! T' flight was unstable and it crashed still under impulse. Fortunately, shiver me timbers, thar was virtually no damage. After a couple o' email exchanges, ya bilge rat, ya bilge rat, we decided t' add some nose weight. Begad! Arrr! Blimey! I wound up attachin' about 1.5 ounces o' washers t' t' nose cone (by replacin' t' screw eye). I also scaled back down t' a D12-5 and tried again t' followin' weekend. This time in heavier winds o' about 10-12 mph, arrr, it flew fine and deployment was right at apogee. Ahoy! After slippin' off into contest flights for a couple months, I got another chance t' fly this on an E9-4 twice. Begad! Blimey! Each flight was wonderful--long, slow, and straight as an arrow (not even a hint o' spin on t' way up) with deployment right at t' top. T' nose weight made all t' difference.

Recovery:
T' beta kit included both an 18" and 20" mylar chute, ya bilge rat, askin' me for feedback on which t' use. I mainly used t' 18", me bucko, matey, but I fly on a field with very tall (2-3 feet) grass and even when I completely forgot t' pack a chute one time, shiver me timbers, matey, soft landings are t' norm. Well, blow me down! Arrr! Blimey! For short grass flying, arrr, I'd probably go with t' larger 20 or 24" chute, me hearties, matey, as t' large fins could be prone to breakin' with t' mixed grain directions. Aye aye! Ahoy! Blimey!

Flight Rating: 5 out o' 5

Summary:
I found this t' be a beautiful rocket with awesome flights on me favorite motor, t' Estes E9. It's definitely an unusual and appealin' design and a break from t' typical commercial fare. T' main PROs are design, performance, and quality o' instructions and materials.

T' only CONs would include soft balsa with lots o' hand cutting, ya bilge rat, matey, the two-piece body tube, arrr, ya bilge rat, and (beta only) lack o' decals.

Overall Rating: 4 out o' 5
