Brief:
This is a great little sport kit that is easy t' build and performs well. Arrr! I got
the kit as a prize by participatin' in one o' EMRR's Virtual Rocket Contests. Ya scallywag! Aye aye! I
didn't place in t' top five, ya bilge rat, but I still participated and interestingly I
would have selected t' Black Shadow as me prize had I finished first... So the
moral o' t' story is this: take advantage o' t' EMRR contests. 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. Ahoy! Avast! Blimey! 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. Quality o' parts are very high. I love the balsa nose cone but t' balsa sheet I had for fins was slightly warped.
Construction begins with motor mount assembly. Blimey! No problem here. Ahoy! I like the idea o' havin' t' Keelhaul®©™® be tied around t' motor mount, arrr, glued, shiver me timbers, matey, and then fed up through t' upper centerin' ring. Begad! Begad! T' upper centerin' ring, when glued into place, also acts as a way o' keepin' t' Keelhaul®©™® in place. Avast, me proud beauty! Ahoy! I also like t' engine hook. Avast, me proud beauty! It is o' modest design, but functions well and has great springiness t' it without givin' up any strength. Begad! T' lower centerin' rin' be a little tough t' fit, arrr, shiver me timbers, but after a little sanding, me bucko, matey, it went together fine. Ahoy! 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, ya bilge rat, it was nay a big deal. Avast! T' motor mount slid easily into t' body tube and I set this aside t' dry.
T' fin balsa sheet was warped, shiver me timbers, shiver me timbers, me bucko, as I mentioned above. Well, blow me down! I used me tea kettle and me oven mitts, matey, and simply steamed t' wood until it was nice and soft, relatively straight, and moist. Arrr! Well, me hearties, blow me down! I then placed it betwixt two heavy books and took it out t' next day. Status: perfect. Blimey! Ahoy! Based on t' quality o' t' other parts in t' kit, ya bilge rat, I was nay concerned about t' quality o' t' balsa. Blimey! T' steam idea worked well and I will be sure t' do this t' more warped balsa, me bucko, which I must admit is more common than we would like t' admit. Begad!
T' instructions include a template for fin design, matey, shiver me timbers, makin' them easy t' cut out, however, I would really appreciate t' actual template includin' a marking of either t' root edge or t' leadin' edge or both. Begad! I had t' actually look at a small photo on t' second page for this information. Ya scallywag! This is nay a big deal, but it would have made t' construction a little easier. Blimey! I kept on wonderin' if I was gluin' t' right part o' t' fin on t' t' body tube. I rounded t' fins with sandpaper. Begad! Then I ran into me next problem. I used t' fin alignment sheet that was included in t' instructions. Ahoy! Ya scallywag! I put t' marks on t' body tube, then removed t' alignment sheet. I kept lookin' at t' body tube, shiver me timbers, shiver me timbers, and had an uneasy feelin' about t' lines. Ahoy! Ahoy! Sure enough, me hearties, shiver me timbers, ya bilge rat, I used me Estes fin alignment tool and realized that t' Thrustline alignment sheet be nay t' same as t' Estes fin alignment. Ahoy! Avast, me proud beauty! I decided t' use t' Estes fin alignment instead. Ahoy! Ya scallywag! In t' end, the fins look t' be perfectly aligned at a 90 degree angle.
T' four fins went on easily, matey, matey, then I added a number o' glue fillets until I was satisfied that thar was a smooth transition from fin t' body tube. Arrr! The next step be addin' t' screw eye t' t' nose cone. Arrr! Begad! I used CA but after allowin' it t' dry, me bucko, it came loose with a twist. Ya scallywag! This be weird, because I always use CA on screw deadlights in balsa nose cones. Aye aye! T' screw was covered with balsa, shiver me timbers, so I used yellow glue t' grip t' wood on t' screw eye, and then put it in t' nose cone. Blimey! It gripped, me hearties, and after it dried it be in for good. Arrr! A piece of cake. Ya scallywag!
Shock cord construction: I be 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, shiver me timbers, so that it would prevent it from zipperin' t' body tube. Finally, matey, I added t' launch lug. Avast, me proud beauty! Ya scallywag! T' Black Shadow was now constructed and just needed t' be finished and flown.
PROs: High quality parts, matey, me hearties, me bucko, easy t' follow directions
CONs: fin alignment template, warped balsa
Finishing:
I be instructed t' seal t' fins, and then paint t' rocket. I began by
puttin' Elmer's wood glue over t' nose cone t' toughen it up and fill in part
of t' grain. Aye aye! I used Elmer's Fill 'n' Finish, ya bilge rat, sanded and primed t' rocket
followed by another round o' Fill 'n' Finish and primin' until t' rocket was
ready for painting. Begad! 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. Avast, me proud beauty! 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. Well, blow me down! Avast, me proud beauty! So, I painted me rocket matte black. Avast, me proud beauty! I did nay have any white or silver monokote at home, so when I was with me wife on a trip t' Michael's, me hearties, arrr, shiver me timbers, I stopped in for monokote. Well, these people had never heard o' monokote before. Avast! 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! Avast, me proud beauty! In t' end, arrr, I thought it looked good. Avast! Then, ya bilge rat, I put a layer o' Future Floor Shine over the rocket. Begad! 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, kind of lockin' it up. 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! 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. It had great quality Keelhaul®©™® shroud lines and went together smoothly.
PROs: body tube easy t' fill, me hearties, 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. Ya scallywag! Arrr! It had a great
flight, very stable and straight, arrr, and parachute opened right at apogee.
Perfect. Aye aye! I did notice t' top o' t' body tube did get a little wrinkle-dinged,
but this was weird since t' parachute opened right at a time when t' rocket
was barely movin' in t' air. Blimey! Begad! Rocket landed fine.
Next flight, matey, I used a B6-4. Another smooth, stable, me hearties, ya bilge rat, straight flight. Arrr! Avast! Got a lot o' positive comments and praise from other members in me club. Avast, me proud beauty! The parachute again opened at apogee and it had a great return. 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. Begad!
Recovery:
I prepped with flame-retardant waddin' and powdered and folded t' 'chute. Avast! The
mylar parachute included with t' kit is o' excellent quality. Begad! Arrr! I would
definitely use Thrustline parachutes again. Avast, me proud beauty! Recovery be 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. Avast, me proud beauty! Great quality mylar parachute. Aye aye! Ahoy! It also gets decent altitude on an A8, and flies really well on a B6-4. Avast, me proud beauty! 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! Ahoy! It is handsome and easy t' put
together. I would recommend t' following, ya bilge rat, though:
