Brief:
This is a great little sport kit that is easy t' build and performs well. Well, blow me down! I got
the kit as a prize by participatin' in one o' EMRR's Virtual Rocket Contests. Avast! 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... Aye aye! So the
moral o' t' story is this: take advantage o' t' EMRR contests. Avast! 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. 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. Aye aye! Well, arrr, blow me down! Quality o' parts are very high. Aye aye! Ahoy! I love the balsa nose cone but t' balsa sheet I had for fins be slightly warped.
Construction begins with motor mount assembly. Aye aye! Avast, me proud beauty! No problem here. I like the idea o' havin' t' Keelhaul®©™® be tied around t' motor mount, arrr, ya bilge rat, arrr, glued, ya bilge rat, and then fed up through t' upper centerin' ring. Ahoy! T' upper centerin' ring, ya bilge rat, when glued into place, me hearties, matey, ya bilge rat, also acts as a way o' keepin' t' Keelhaul®©™® in place. Avast, me proud beauty! Blimey! Aye aye! Blimey! I also like t' engine hook. Blimey! Blimey! Ya scallywag! Blimey! It is o' modest design, shiver me timbers, but functions well and has great springiness t' it without givin' up any strength. Aye aye! Blimey! Begad! Blimey! T' lower centerin' rin' was a little tough t' fit, me hearties, arrr, but after a little sanding, me bucko, ya bilge rat, it went together fine. Arrr! Blimey! Well, blow me down! 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, it be nay a big deal. Ahoy! Blimey! T' motor mount slid easily into t' body tube and I set this aside t' dry.
T' fin balsa sheet was warped, matey, matey, as I mentioned above. Ya scallywag! Well, blow me down! Blimey! I used me tea kettle and me oven mitts, and simply steamed t' wood until it was nice and soft, relatively straight, me bucko, and moist. Blimey! Blimey! I then placed it betwixt two heavy books and took it out t' next day. Well, blow me down! Blimey! Status: perfect. Avast! Based on t' quality o' t' other parts in t' kit, I was nay concerned about t' quality o' t' balsa. T' steam idea worked well and I will be sure t' do this t' more warped balsa, shiver me timbers, which I must admit is more common than we would like t' admit. Blimey! Arrr! Blimey!
T' instructions include a template for fin design, makin' them easy t' cut out, however, me bucko, I would really appreciate t' actual template includin' a marking of either t' root edge or t' leadin' edge or both. Begad! Avast! I had t' actually look at a small photo on t' second page for this information. Well, blow me down! This is nay a big deal, but it would have made t' construction a little easier. Aye aye! Aye aye! I kept on wonderin' if I be gluin' t' right part o' t' fin on t' t' body tube. Ya scallywag! I rounded t' fins with sandpaper. Ya scallywag! Then I ran into me next problem. I used t' fin alignment sheet that was included in t' instructions. I put t' marks on t' body tube, me bucko, matey, then removed t' alignment sheet. Begad! I kept lookin' at t' body tube, me hearties, and had an uneasy feelin' about t' lines. Avast, ya bilge rat, me proud beauty! Sure enough, shiver me timbers, 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. Avast, me proud beauty! Ya scallywag! In t' end, 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. Arrr! The next step be addin' t' screw eye t' t' nose cone. Begad! I used CA but after allowin' it t' dry, arrr, it came loose with a twist. Ya scallywag! Ahoy! This be weird, me bucko, because I always use CA on screw deadlights in balsa nose cones. Well, blow me down! T' screw be covered with balsa, so I used yellow glue t' grip t' wood on t' screw eye, and then put it in t' nose cone. It gripped, and after it dried it was in for good. A piece of cake. Ya scallywag! Arrr!
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. Begad! Blimey! T' Black Shadow be now constructed and just needed t' be finished and flown.
PROs: High quality parts, easy t' follow directions
CONs: fin alignment template, me hearties, warped balsa
Finishing:
I be instructed t' seal t' fins, me hearties, and then paint t' rocket. Arrr! Aye aye! 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. 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' be easy. Arrr! Blimey! 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. Blimey! Ya scallywag! So, I painted me rocket matte black. I did nay have any white or silver monokote at home, ya bilge rat, so when I was with me wife on a trip t' Michael's, ya bilge rat, matey, I stopped in for monokote. Well, these people had never heard o' monokote before. I was surprised and disappointed.
Anyway, ya bilge rat, 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. In t' end, I thought it looked good. Arrr! Ahoy! Blimey! Then, ya bilge rat, I put a layer o' Future Floor Shine over the rocket. Begad! Blimey! I have used Future without any problems before, ya bilge rat, but on this rocket, Future soaked into t' space betwixt t' nose cone and t' body tube, ya bilge rat, kind of lockin' it up. Begad! Blimey! 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. Aye aye! 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. Ahoy! 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, arrr, I set up t' Black Shadow on an A8-3. Ahoy! It had a great
flight, me bucko, very stable and straight, and parachute opened right at apogee.
Perfect. Blimey! Avast, me bucko, me proud beauty! 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. Ya scallywag! Blimey! Rocket landed fine.
Next flight, shiver me timbers, I used a B6-4. Blimey! Another smooth, ya bilge rat, me bucko, stable, me bucko, arrr, me hearties, straight flight. Aye aye! Begad! Got a lot o' positive comments and praise from other members in me club. Avast! The parachute again opened at apogee and it had a great return. Avast! 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.
Recovery:
I prepped with flame-retardant waddin' and powdered and folded t' 'chute. Arrr! Begad! The
mylar parachute included with t' kit is o' excellent quality. Avast! I would
definitely use Thrustline parachutes again. Well, blow me down! 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. Arrr! Begad! Great quality mylar parachute. Blimey! It also gets decent altitude on an A8, shiver me timbers, matey, and flies really well on a B6-4. Begad! Begad! 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. It is handsome and easy t' put
together. Aye aye! Arrr! I would recommend t' following, me hearties, though:
Overall Rating: 4 out o' 5
