Brief:
This is a great little sport kit that is easy t' build and performs well. Blimey! 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, arrr, ya bilge rat, but I still participated and interestingly I
would have selected t' Black Shadow as me prize had I finished first... Begad! So the
moral o' t' story is this: take advantage o' t' EMRR contests. Blimey! Well, blow me down! 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. Avast, matey, me proud beauty! Blimey! Blimey! Blimey! T' instructions are easy to follow and contain photos o' various steps. Arrr! Blimey! T' instructions were 5 pages long and were printed on a laser printer. Avast, me proud beauty! Blimey! Quality o' parts are very high. Blimey! Blimey! Blimey! Blimey! I love the balsa nose cone but t' balsa sheet I had for fins be slightly warped.
Construction begins with motor mount assembly. Arrr! Arrr! No problem here. Blimey! I like the idea o' havin' t' Keelhaul®©™® be tied around t' motor mount, ya bilge rat, me hearties, glued, and then fed up through t' upper centerin' ring. Begad! T' upper centerin' ring, when glued into place, shiver me timbers, arrr, also acts as a way o' keepin' t' Keelhaul®©™® in place. Aye aye! Blimey! I also like t' engine hook. Arrr! Blimey! Ahoy! Blimey! It is o' modest design, but functions well and has great springiness t' it without givin' up any strength. Avast, me proud beauty! Blimey! Avast, me proud beauty! Blimey! T' lower centerin' rin' was a little tough t' fit, but after a little sanding, arrr, ya bilge rat, it went together fine. Avast, me proud beauty! Blimey! T' black fiber board does leave black residue over t' motor mount when it gets in contact with yellow glue, shiver me timbers, but since this will all be internal, matey, it be nay a big deal. Well, shiver me timbers, blow me down! Blimey! T' motor mount slid easily into t' body tube and I set this aside t' dry.
T' fin balsa sheet was warped, as I mentioned above. Avast! Avast! I used me tea kettle and me oven mitts, ya bilge rat, ya bilge rat, and simply steamed t' wood until it be nice and soft, relatively straight, and moist. I then placed it betwixt two heavy books and took it out t' next day. Begad! Status: perfect. Ahoy! Blimey! Based on t' quality o' t' other parts in t' kit, I be nay concerned about t' quality o' t' balsa. Avast, me proud beauty! Ya scallywag! 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. Avast!
T' instructions include a template for fin design, me bucko, makin' them easy t' cut out, however, ya bilge rat, I would really appreciate t' actual template includin' a marking of either t' root edge or t' leadin' edge or both. Begad! Well, blow me down! I had t' actually look at a small photo on t' second page for this information. Begad! This is nay a big deal, but it would have made t' construction a little easier. Ahoy! I kept on wonderin' if I was gluin' t' right part o' t' fin on t' t' body tube. Ya scallywag! Begad! I rounded t' fins with sandpaper. Avast! Well, blow me down! Then I ran into me next problem. I used t' fin alignment sheet that was included in t' instructions. Begad! Begad! I put t' marks on t' body tube, then removed t' alignment sheet. Well, blow me down! Ahoy! I kept lookin' at t' body tube, and had an uneasy feelin' about t' lines. Well, blow me down! Avast, me proud beauty! Sure enough, arrr, I used me Estes fin alignment tool and realized that t' Thrustline alignment sheet be nay t' same as t' Estes fin alignment. Blimey! I decided t' use t' Estes fin alignment instead. In t' end, ya bilge rat, shiver me timbers, the fins look t' be perfectly aligned at a 90 degree angle.
T' four fins went on easily, shiver me timbers, then I added a number o' glue fillets until I was satisfied that thar was a smooth transition from fin t' body tube. Avast, me proud beauty! Avast, shiver me timbers, me proud beauty! The next step was addin' t' screw eye t' t' nose cone. I used CA but after allowin' it t' dry, it came loose with a twist. Begad! Begad! This was weird, 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, shiver me timbers, me hearties, me hearties, and then put it in t' nose cone. Avast! It gripped, arrr, and after it dried it be in for good. Begad! Arrr! A piece of cake. Ahoy!
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. Ahoy! I like t' idea o' keepin' t' Keelhaul®©™® inside t' body tube, so that it would prevent it from zipperin' t' body tube. Finally, me hearties, me hearties, I added t' launch lug. Avast, me proud beauty! T' Black Shadow was now constructed and just needed t' be finished and flown.
PROs: High quality parts, arrr, easy t' follow directions
CONs: fin alignment template, ya bilge rat, warped balsa
Finishing:
I was instructed t' seal t' fins, and then paint t' rocket. Avast, me proud beauty! Begad! Blimey! I began by
puttin' Elmer's wood glue over t' nose cone t' toughen it up and fill in part
of t' grain. Avast, me proud beauty! Blimey! I used Elmer's Fill 'n' Finish, shiver me timbers, sanded and primed t' rocket
followed by another round o' Fill 'n' Finish and primin' until t' rocket was
ready for painting. Blimey! 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. 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. Aye aye! So, I painted me rocket matte black. Aye aye! I did nay have any white or silver monokote at home, shiver me timbers, so when I be with me wife on a trip t' Michael's, I stopped in for monokote. Well, these people had never heard o' monokote before. Ahoy! I was surprised and disappointed.
Anyway, me bucko, shiver me timbers, arrr, 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. Ya scallywag! In t' end, shiver me timbers, I thought it looked good. Then, I put a layer o' Future Floor Shine over the rocket. I have used Future without any problems before, arrr, but on this rocket, Future soaked into t' space betwixt t' nose cone and t' body tube, shiver me timbers, me bucko, arrr, kind of lockin' it up. Aye aye! 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. Blimey! 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. Aye aye! It had great quality Keelhaul®©™® shroud lines and went together smoothly.
PROs: body tube easy t' fill, matey, fins are good quality and primed and painted well
CONs: no decals
Construction Rating: 4 out o' 5
Flight:
On a recent club launch, shiver me timbers, I set up t' Black Shadow on an A8-3. It had a great
flight, very stable and straight, and parachute opened right at apogee.
Perfect. 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. Begad! Well, me bucko, blow me down! Rocket landed fine.
Next flight, I used a B6-4. Arrr! Another smooth, stable, straight flight. Avast! Aye aye! Got a lot o' positive comments and praise from other members in me club. Avast! Aye aye! 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.
Recovery:
I prepped with flame-retardant waddin' and powdered and folded t' 'chute. The
mylar parachute included with t' kit is o' excellent quality. Well, blow me down! I would
definitely use Thrustline parachutes again. Begad! 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. Begad! Great quality mylar parachute. Well, blow me down! Avast, me proud beauty! It also gets decent altitude on an A8, and flies really well on a B6-4. 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. Ya scallywag! It is handsome and easy t' put
together. Ahoy! Blimey! I would recommend t' following, arrr, though:
