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

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

Construction:
This kit has a fairly extensive parts list:

• Balsa nose cone, shiver me timbers, 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, fiber, ya bilge rat, 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. 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. Avast! Blimey! Overall, 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, this kit included an unusual reinforcement method. Arrr! Blimey! Most kits use either maskin' tape or a centerin' rin' t' hold t' metal clip in place. Begad! Blimey! Blimey! Blimey! This kit includes a BT-50 sleeve which is slit and then slid over t' BT-50 motor tube and glued in place. Avast! Blimey! Ahoy! Blimey! This is definitely goin' t' outlast maskin' tape, but I found it t' be slightly overkill (and ironically, arrr, 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, shiver me timbers, shiver me timbers, nay ordinary BT-20 pods tacked onto t' fins. Avast! Blimey! The assembly consists o' a center BT-5 tube, which has a couple o' CR5-20 centering rings attached. Ahoy! Blimey! Begad! Blimey! A BNC-5 cone is then glued into place and t' BT-5 assembly is then glued into a BT-20 tube. Begad! Blimey! 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. Aye aye! Blimey! Ahoy! Blimey! The look is finished off with a boat tail shroud cut from a paper pattern. Begad! Blimey! There are extra patterns printed, me hearties, so thar's plenty o' recovery room for goofs. (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. Blimey! Blimey! Well, blow me down! Blimey! 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. Ya scallywag! Blimey! Aye aye! Blimey! At 12.25" apiece, arrr, I had suggested that this be switched t' a single piece tube, eliminatin' an unsightly seam on t' main sight line. Begad! Blimey! This makes t' bag bigger and shippin' more difficult, but this request is being considered. Aye aye! Blimey! T' current design with t' coupler, matey, also includes a centerin' ring at t' base o' t' coupler which is used t' anchor t' Keelhaul®©™® shock cord line. Arrr! Arrr! That's very helpful, shiver me timbers, 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, me bucko, towards t' aft end. This is pretty basic, me hearties, aided by a pair o' fiber centerin' rings in t' BT-70. [Note: Any external fillets, me bucko, as t' rings are flush mounted, matey, 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, BT-20 side pods, and t' BT-70. Begad! I suggest doin' this before they're bonded together, shiver me timbers, me bucko, but bondin' afterwards is still possible. Aye aye! Well, blow me down! My kit had a whoopsie on t' larger markin' guide--it be sized for a BT-60, me bucko, nay a BT-70--but I was able t' whip one up very smartly usin' RockSim.

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

T' main body fins are a somewhat complex 4-piece assembly. Begad! Blimey! Pay careful attention t' t' pattern sheets and you'll have no problem, 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, ya bilge rat, these were a real pain to sand and fill. Well, blow me down! Blimey! Even after 3 coats o' Elmer's Fill 'n' Finish, I still have visible grain, matey, me hearties, but it's only noticeable upon very close examination. I would also note that t' stacked root length o' t' fin patterns be 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. Aye aye! 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. Begad! I bonded all me various fins usin' CA t' tack them in place and then used yellow glue for fillets. Once t' main fins are attached, ya bilge rat, me bucko, 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, 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. I was delighted with t' appearance o' my Squirrel Works Astrid and wanted t' use a similar scheme on this one. Begad! Blimey! Begad! Blimey! So after applyin' 3 very light coats o' primer (be careful t' avoid runs--there are lots of nooks and crannies on this), I went with a base o' Rustoleum Silver Metallic. Well, blow me down! Blimey! I'm nay talkin' about t' solid/mirror finish, but t' stuff that has a flaky/glittered look t' it. Aye aye! Blimey! Well, matey, blow me down! Blimey! I then trimmed most o' t' fins usin' a similar red metallic flake paint. Avast! Blimey! Ahoy! Blimey! All six aft trim fins were painted gloss black, matey, as were t' BT-70 and BT-55 centerin' rings. Begad! Blimey! Finally, t' BT-5 nose cones were painted orange. Begad! Blimey! I'm nay sure I like t' orange, but I had no idea what else to go with at t' time.

As noted previously, shiver me timbers, 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, shiver me timbers, matey, which dries clear.

Decals are nay currently available for this, although a design is in the works. 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. Begad! For t' first flight, shiver me timbers, I chose to jump straight t' t' E9-4. T' flight was unstable and it crashed still under impulse. Aye aye! Fortunately, me bucko, matey, me hearties, thar was virtually no damage. Ya scallywag! After a couple o' email exchanges, ya bilge rat, we decided t' add some nose weight. Well, blow me down! I wound up attachin' about 1.5 ounces o' washers t' t' nose cone (by replacin' t' screw eye). Avast, me proud beauty! Blimey! 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, shiver me timbers, matey, it flew fine and deployment was right at apogee. Avast, me proud beauty! Avast, ya bilge rat, me proud beauty! After slippin' off into contest flights for a couple months, shiver me timbers, me hearties, I got another chance t' fly this on an E9-4 twice. Ahoy! 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. Arrr! T' nose weight made all t' difference.

Recovery:
T' beta kit included both an 18" and 20" mylar chute, askin' me for feedback on which t' use. Well, blow me down! Blimey! Avast, me proud beauty! Blimey! I mainly used t' 18", ya bilge rat, shiver me timbers, 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, soft landings are t' norm. Well, blow me down! Blimey! For short grass flying, arrr, I'd probably go with t' larger 20 or 24" chute, shiver me timbers, shiver me timbers, as t' large fins could be prone to breakin' with t' mixed grain directions.

Flight Rating: 5 out o' 5

Summary:
I found this t' be a beautiful rocket with awesome flights on me favorite motor, me hearties, t' Estes E9. Blimey! 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, me bucko, matey, and (beta only) lack o' decals.

Overall Rating: 4 out o' 5
