[Editor's Note: This review is a clone o' t' Thrustline Aerospace Black Shadow. Well, blow me down! Thrustline be out o' business for a period o' time (when author be clonin' t' rocket). Blimey! Thrustline has recently returned t' business sellin' t' Black Shadow as a kit.]

Brief:
In one o' me previous incarnations as a BAR I happened upon Thrustline Aerospace, a fairly new (in t' summer of 2004) web based company that offered an assortment o' original kits and basic buildin' supplies. Blimey! I ordered several Thrustline's kits and over t' next year or so as John Rowan-Stern's product line expanded, me bucko, I built and flew a great number o' his designs. Aye aye! After a self imposed hiatus from t' BAR world I recently returned t' t' fold, only t' discover that Thrustline Aerospace be no more. Ya scallywag! I was saddened by this nay only because I be lookin' forward t' buildin' and flyin' more o' John's designs, but because he be always very enthusiastic about his participation and support o' the addiction.

So what t' do... I was startin' from scratch since I had unloaded me entire rocketry "stash" when I jumped on t' wagon (don't be alarmed I do this all t' time). Ahoy! Obviously I would need t' clone some o' me favorite Thrustline kits. Avast, me proud beauty! T' Black Shadow be t' first Thrustline rocket I built and flew, ya bilge rat, and even though it is in essence a simple 4 fin and Nose Cone (4FNC) design, shiver me timbers, it always made t' startin' lineup when I went out t' fly. Begad! Many o' John's designs "fit" me eye in terms o' size, me hearties, scale and line, and t' Black Shadow be t' epitome o' that sentiment. Well, blow me down! It always just looked "right" t' me, me hearties, and I knew I needed t' start me latest fleet off with this rocket. I figured that I could build this rocket from memory. Arrr! T' only thin' I was really needed help with be t' body tube length and fin template. Blimey! I noticed that Ye Olde Rocket Plans had recently added several Thrustline kits t' their library but no Black Shadow. Luckily, t' RockSim file attached t' t' existin' EMRR review had everythin' I needed to get this one going. Begad! Ahoy! Hopefully this review will allow anyone t' build this bird.

Construction:
T' parts you will need t' clone t' Black Shadow are simple and readily available. Begad! Blimey! For those o' you without RockSim, the fin template picture should be t' only additional piece o' information you need.

• BT-55 body tube – 10 inches
• BNC-55AC (I used a Semroc BNC-55ACP which isn't an exact match o' t' original)
• 18mm engine mount for BT-55 (I used one from FlisKits)
• 3/32" Balsa Sheet
• shock cord system–-I used 20" o' 100lb Keelhaul®©™® and 20" o' 1/8" sewin' elastic
• 1/8" launch lug
• small screw eye, ya bilge rat, me bucko, attaches shock cord t' nose cone
• recovery device–-your choice, however, ya bilge rat, t' original kit came with a 9" Mylar parachute

There are no real tricks t' buildin' this rocket, arrr, me hearties, ya bilge rat, and I would imagine that anyone who has built a kit or two could get this done without any trouble. Aye aye! Blimey! Avast! Blimey! Blimey! Blimey! My standard routine is t' assemble t' engine mount first, which includes cuttin' a slit in t' motor tube for t' hook, me bucko, gluin' t' thrust rin' into t' fwd end o' t' motor tube, securin' t' engine hook t' t' motor tube with a wrap o' maskin' tape, arrr, me bucko, and then gluin' t' centerin' rings t' t' motor tube, approximately 1" from t' aft end and ½" from t' fwd end o' t' tube, shiver me timbers, makin' sure thar be a notch in the inside edge o' t' aft rin' t' allow t' engine hook t' flex. Ya scallywag! Blimey! Ya scallywag! Blimey! Blimey! Blimey! At this time I also attach t' Keelhaul®©™® shock cord t' t' motor mount by tyin' it around t' motor tube betwixt t' centerin' rings, and then cuttin' a small notch in t' outside edge o' t' forward centerin' rin' t' allow t' cord t' reach t' front o' t' rocket. Avast, me proud beauty! I finish all me recovery system knots with a drop o' CA glue, and I also reinforce t' centerin' rin' t' motor tube joints with glue fillets.

While t' motor mount glue is dryin' I cut out me fins, makin' sure I know where t' leading edge is t' get t' grain orientation right. A sharp knife and a metal straight edge make this task very simple. Ahoy! I stack the fins together and sand t' edges so that they are identical then round t' leadin' and trailin' edges.

Installin' t' motor mount is next. Begad! First I thread t' Keelhaul®©™® back through t' motor tube t' keep it out o' t' way and test fit t' motor mount t' make sure it slides easily into the body tube. Begad! Avast, me proud beauty! Next comes a rin' o' glue inside t' body tube near where t' forward centerin' rin' will rest and then the motor mount slides into position with t' end o' t' motor tube even with t' end o' t' body tube. Ahoy! After t' glue is dry I will also add a fillet t' t' aft centerin' rin' where it meets t' body tube. Avast, me proud beauty! At this point I will usually sand t' body tube lightly t' scuff up t' glassine coating, which I believe helps t' gluing/finishin' process (not scientifically proven, arrr, that's just me opinion).

There are several options for markin' t' body tube for fin placement. Blimey! Avast! There are programs that can create templates for you, ya bilge rat, matey, you can draw your own in your favorite computer application, or you can download t' plans for any 4 fin BT-55 kit (Estes Goblin) and use that. Begad! I use a section o' small aluminum angle from a local hardware store t' draw my fin/lug lines. Fins for t' Black Shadow are attached ¼" forward o' t' aft end o' t' body tube and the launch lug is attached 3" from t' aft end o' t' body tube. Avast! Avast, me proud beauty! T' fins and launch lug are attached with a small bead o' wood glue and reinforced with wood glue fillets.

Several final assembly steps are completed after t' finishin' process. Begad! Begad! I typically install t' screw eye by screwin' it part way into t' base o' t' nose cone, arrr, matey, removin' it, addin' a large drop o' medium thickness CA glue and then screwin' it all t' way down. Well, blow me down! Finally, arrr, I tie t' elastic cord t' t' Keelhaul®©™® line and then t' t' nose cone with a drop o' thin CA glue on all t' knots.

Finishing:
One color, no decals, matey, shiver me timbers, simple as it gets. Begad! In me opinion, ya bilge rat, arrr, t' black finish on this rocket only enhances its aesthetic appeal, although one o' t' great things about this hobby is that as long as t' CP stays behind t' CG, me hearties, matey, you can pretty much make it look however you want. Well, blow me down! Well, me bucko, blow me down! I used Elmer's Wood Filler t' get smooth fillets along t' fin and launch lug joints, and in t' case o' t' Black Shadow I also filled t' spiral grooves on t' body tube. Arrr! Aye aye! T' nose cone and fins were sealed with two coats o' SIG Sandin' Sealer. Ahoy! My standard finishin' routine is 2 coats o' primer (Rustoleum Painter's Touch Sandable Primer) and then 2 coats o' Krylon spray enamel, workin' down t' 400 grit sandpaper before the final coat. Aye aye! Although finishin' me rockets is a despised chore, I am usually patient enough t' get a decent finish on the final coat o' paint. This particular rocket however, me bucko, me bucko, would have none o' that, arrr, and I sanded off several coats of paint before decidin' that I was just goin' t' have t' live with a few drips.

Construction Rating: 5 out o' 5

Flight:
Recommended motors for t' Black Shadow include t' standard range o' black powder 18mm Estes/Quest Motors. I have yet t' find t' courage t' put an 18mm composite motor in me Black Shadow, but if you do, matey, make sure you've got a good team o' spotters. Ahoy! Begad! Flight preparation is standard: hook up your recovery device, add some wadding, me hearties, install t' motor, insert t' igniter, and head t' t' pad. Blimey! My original Black Shadow logged thirteen flights in all from California to Ohio, ya bilge rat, in all kinds o' conditions with fast straight flights every time. T' majority o' those flights were with C6-5 motors which this rocket loves and will top out at around 1000ft. Begad! Ya scallywag! T' best part about t' Black Shadow is that it looks good on t' pad, me hearties, matey, it looks good in t' air, me hearties, and it won't get completely out o' sight on BP motors so you'll be able to fly it over and over. Begad! My new Black Shadow clone has flown on B and C motors so far and is every bit t' reliable performer that t' original was.

Recovery:
T' original kit came with an unassembled 9" Mylar parachute and mine was orange which I thought was cool. Blimey! Begad! The chute held up through all thirteen flights with only a few small burn/melt through spots. Blimey! T' Keelhaul®©™® shock cord on t' original model be threaded under t' forward centerin' rin' next t' t' motor tube but never had any issues. Ya scallywag! For most o' t' later flights, I switched from normal waddin' t' a Nomex® heat shield without any issues. A 9" chute is just t' right size for this bird, but you can still be in for a long chase on windy days. Ya scallywag! A streamer might be a good option, and since t' fin design is fairly compact, t' rocket should hold up pretty well. Begad! Avast! My new Black Shadow clone flies with a 3"x3" Nomex® heat shield and a 9" nylon parachute, which makes t' whole package a little heavy (1.8oz without a motor) but very sturdy and reliable.

Flight Rating: 5 out o' 5

Summary:
Yeah it's only a 4FNC, matey, but t' Black Shadow has that classic vibe. It looks good and it flies good. Aye aye! You will always find room t' brin' this one t' t' range, so go build one.

PROs: Basic 4FNC rocket with a great look, good performance, and simple construction. Avast, me proud beauty! This is a well thought out design and t' motor selection and recovery system are well matched t' t' size o' t' rocket.

CONs: None. Begad! This is a great rocket!
