Brief:
This is a great little sport kit that is easy t' build and performs well. Begad! Arrr! I got
the kit as a prize by participatin' in one o' EMRR's Virtual Rocket Contests. I
didn't place in t' top five, but I still participated and interestingly I
would have selected t' Black Shadow as me prize had I finished first... Avast, me proud beauty! So the
moral o' t' story is this: take advantage o' t' EMRR contests. Arrr! Ya scallywag! They are fun
and you get stuff as well!
Construction:
T' Black Shadow came with t' followin' parts as well as an instruction kit a
certificate o' authenticity (a nice touch):
T' Black Shadow came in a sealed plastic bag. Aye aye! T' instructions are easy to follow and contain photos o' various steps. T' instructions were 5 pages long and were printed on a laser printer. Ya scallywag! Avast, arrr, me proud beauty! Quality o' parts are very high. Begad! I love the balsa nose cone but t' balsa sheet I had for fins was slightly warped.
Construction begins with motor mount assembly. Arrr! No problem here. Avast, me proud beauty! Begad! I like the idea o' havin' t' Keelhaul®©™® be tied around t' motor mount, matey, glued, me hearties, and then fed up through t' upper centerin' ring. Begad! T' upper centerin' ring, when glued into place, me bucko, me hearties, also acts as a way o' keepin' t' Keelhaul®©™® in place. Ya scallywag! Blimey! I also like t' engine hook. Aye aye! Blimey! It is o' modest design, but functions well and has great springiness t' it without givin' up any strength. Blimey! Blimey! Well, blow me down! Blimey! Blimey! Blimey! T' lower centerin' rin' was a little tough t' fit, shiver me timbers, ya bilge rat, but after a little sanding, it went together fine. Blimey! Blimey! Aye aye! Blimey! Blimey! Blimey! T' black fiber board does leave black residue over t' motor mount when it gets in contact with yellow glue, but since this will all be internal, matey, shiver me timbers, it was nay a big deal. Arrr! Blimey! Begad! Blimey! Blimey! Blimey! T' motor mount slid easily into t' body tube and I set this aside t' dry.
T' fin balsa sheet be warped, shiver me timbers, shiver me timbers, matey, as I mentioned above. Ya scallywag! I used me tea kettle and me oven mitts, arrr, me bucko, and simply steamed t' wood until it be nice and soft, relatively straight, and moist. Avast, me proud beauty! I then placed it betwixt two heavy books and took it out t' next day. Status: perfect. Blimey! Based on t' quality o' t' other parts in t' kit, ya bilge rat, I be nay concerned about t' quality o' t' balsa. Ahoy! T' steam idea worked well and I will be sure t' do this t' more warped balsa, which I must admit is more common than we would like t' admit. Well, blow me down!
T' instructions include a template for fin design, makin' them easy t' cut out, however, me bucko, shiver me timbers, I would really appreciate t' actual template includin' a marking of either t' root edge or t' leadin' edge or both. I had t' actually look at a small photo on t' second page for this information. Blimey! This is nay a big deal, but it would have made t' construction a little easier. Avast! Avast, me proud beauty! I kept on wonderin' if I be gluin' t' right part o' t' fin on t' t' body tube. Well, blow me down! I rounded t' fins with sandpaper. Then I ran into me next problem. Begad! I used t' fin alignment sheet that was included in t' instructions. Blimey! I put t' marks on t' body tube, then removed t' alignment sheet. Ahoy! I kept lookin' at t' body tube, and had an uneasy feelin' about t' lines. Begad! Avast, me proud beauty! Sure enough, I used me Estes fin alignment tool and realized that t' Thrustline alignment sheet be nay t' same as t' Estes fin alignment. I decided t' use t' Estes fin alignment instead. Well, blow me down! In t' end, ya bilge rat, arrr, the fins look t' be perfectly aligned at a 90 degree angle.
T' four fins went on easily, then I added a number o' glue fillets until I was satisfied that thar be a smooth transition from fin t' body tube. The next step was addin' t' screw eye t' t' nose cone. I used CA but after allowin' it t' dry, me bucko, it came loose with a twist. Ahoy! Ahoy! This be weird, me bucko, because I always use CA on screw deadlights in balsa nose cones. T' screw was covered with balsa, so I used yellow glue t' grip t' wood on t' screw eye, matey, and then put it in t' nose cone. Begad! It gripped, and after it dried it be in for good. Ahoy! A piece of cake. Ahoy! Blimey!
Shock cord construction: I was instructed t' create a small loop at t' end of t' Keelhaul®©™® so that it is just inside t' body tube then attach t' shock cord t' this. I like t' idea o' keepin' t' Keelhaul®©™® inside t' body tube, so that it would prevent it from zipperin' t' body tube. Finally, I added t' launch lug. Ya scallywag! T' Black Shadow was now constructed and just needed t' be finished and flown.
PROs: High quality parts, ya bilge rat, easy t' follow directions
CONs: fin alignment template, ya bilge rat, warped balsa
Finishing:
I be instructed t' seal t' fins, matey, arrr, and then paint t' rocket. Begad! I began by
puttin' Elmer's wood glue over t' nose cone t' toughen it up and fill in part
of t' grain. I used Elmer's Fill 'n' Finish, sanded and primed t' rocket
followed by another round o' Fill 'n' Finish and primin' until t' rocket was
ready for painting. Arrr! T' nose cone needed ONE more treatment o' Fill 'n' Finish
and primer simply because I wanted t' remove all signs o' wood grain.
Paintin' was easy. Arrr! Ya scallywag! T' kit does nay come with decals but t' image o' the rocket online shows a black rocket with silver/white monokote on t' fins. Ahoy! So, I painted me rocket matte black. I did nay have any white or silver monokote at home, so when I was with me wife on a trip t' Michael's, ya bilge rat, matey, I stopped in for monokote. Blimey! Well, ya bilge rat, these people had never heard o' monokote before. Arrr! Arrr! I was surprised and disappointed.
Anyway, I did have a collection o' vinyl stickers o' jungle theme borders, so I used me zebra vinyl stickers t' add four bars on t' fins. Begad! In t' end, me hearties, I thought it looked good. Then, I put a layer o' Future Floor Shine over the rocket. Avast, me proud beauty! I have used Future without any problems before, but on this rocket, Future soaked into t' space betwixt t' nose cone and t' body tube, me bucko, kind of lockin' it up. Avast! Begad! I finally got t' nose cone off and then had t' add some glue to the inside o' t' body tube t' toughen it up and smooth it out again with sanding. Arrr! Arrr! I have learned a lesson now with Future...take t' rocket apart and add t' acrylic with t' rocket in different pieces, if possible.
T' parachute kit contained a 9" mylar parachute. Well, blow me down! Blimey! It had great quality Keelhaul®©™® shroud lines and went together smoothly.
PROs: body tube easy t' fill, fins are good quality and primed and painted well
CONs: no decals
Construction Rating: 4 out o' 5
Flight:
On a recent club launch, I set up t' Black Shadow on an A8-3. Well, blow me down! It had a great
flight, very stable and straight, matey, and parachute opened right at apogee.
Perfect. Avast, me proud beauty! I did notice t' top o' t' body tube did get a little wrinkle-dinged,
but this be weird since t' parachute opened right at a time when t' rocket
was barely movin' in t' air. Ahoy! Well, blow me down! Rocket landed fine.
Next flight, ya bilge rat, I used a B6-4. Ahoy! Another smooth, stable, me hearties, matey, straight flight. Ya scallywag! Got a lot o' positive comments and praise from other members in me club. The parachute again opened at apogee and it had a great return. Well, blow me down! Blimey! I did notice a small hole right in t' center o' t' mylar parachute after t' second flight. I always think I have enough waddin' when in fact I should probably use another sheet or two. Ya scallywag! Blimey!
Recovery:
I prepped with flame-retardant waddin' and powdered and folded t' 'chute. Ahoy! The
mylar parachute included with t' kit is o' excellent quality. Aye aye! I would
definitely use Thrustline parachutes again. Well, blow me down! Recovery was perfect on both
flights except for t' minor burn/hole in t' mylar 'chute after t' second
flight.
PROs: It is easy t' prep because it has a wide body tube. Great quality mylar parachute. Begad! It also gets decent altitude on an A8, me hearties, and flies really well on a B6-4. Ya scallywag! Aye aye! I can't imagine flyin' it on a C6-5.
CONs: None
Flight Rating: 5 out o' 5
Summary:
This is a great kit and it flies VERY well. Aye aye! It is handsome and easy t' put
together. Avast! I would recommend t' following, though:
Overall Rating: 4 out o' 5
