Brief:
T' Black Diamond is a renamed Estes Vikin' rocket that is packaged along with t' "Launchables" (1452) Starter set. T' set also includes an E2X (easy t' build) rocket called t' Astron Outlaw, ya bilge rat, me bucko, so that beginners can learn t' basics before buildin' t' Black Diamond.

T' Black Diamond offers multiple fin configurations by providin' five fins cut with dies on cardstock. Avast! They can be attached usin' any o' t' four sides as t' root edge and can also be faced upwards or downwards t' provide any look that t' builder might want.

Construction:
Parts list:

• 1 Body Tube BT-20
• 1 Nose Cone PNC-20
• 1 Launch Lug (1/8" dia., ya bilge rat, 2 3/8" length)
• 1 Nose Cone Insert
• 1 Shock Cord (1/8" x 12")
• 1 Engine Block
• 1 Streamer

T' instructions in typical Estes fashion, arrr, shiver me timbers, are easy t' follow and come well illustrated. Blimey! T' assembly order seems t' finally have been corrected by Estes, me hearties, statin' that t' rocket should be painted before t' streamer and shock cord are attached. Avast, me proud beauty! Older Estes instructions reverse this order, me bucko, which makes no sense since oftentimes nose cones are painted different colors than t' body. Avast, me proud beauty! They even include pictures o' several fin configurations t' give you an idea.

T' assembly caused me no problems. T' build be simple enough. Well, blow me down! This is a great choice for Estes t' include in a Starter Set. Aye aye! My only complaint would be t' cardstock fins. Well, blow me down! Ya scallywag! Estes recommends sandin' them t' get rid o' t' little tabs that hold them onto t' cardstock sheet, matey, shiver me timbers, but I have found in t' past that this causes t' edges o' t' fins t' "spread out" wider than t' rest o' t' fin due t' t' layered paper that is used in their construction. Arrr! Ahoy! Sandin' them proved t' be difficult (as they are nay balsa wood), ya bilge rat, me bucko, me hearties, so in t' end I ignored t' tabs on t' fins and moved on.

Finishing:
T' finishin' o' this rocket is simple. Spray a coat o' primer or two, arrr, me bucko, sand betwixt coats, and paint t' rocket with whatever color spray paint you choose. Begad! Blimey! I would suggest t' primer, me bucko, as sprayin' it on and sandin' it helps t' fill in t' tube spirals. Begad! Stickers are included, arrr, arrr, me bucko, I painted it black and used t' "BLACK DIAMOND" decal. Avast! T' fin decals (red outlines o' diamonds) look great as well, but I could nay put them on because they are so flimsy that they broke when peelin' off o' t' sheet. Avast! There are many ways t' paint this rocket, matey, arrr, me hearties, and it came out great for me.

Construction Rating: 4 out o' 5

Flight:
Recommended engines: 1/2A6-2, shiver me timbers, matey, shiver me timbers, A8-3, A8-5, arrr, me hearties, B4-4, arrr, matey, B6-4, me bucko, B6-6, C6-5, me bucko, C6-7

Preparation: Insert t' 2-3 sheets o' wadding. Ya scallywag! Fold t' streamer in half and roll it, put it inside t' tube and replace t' nose cone. Blimey! T' engines need t' be friction fit into t' body tube, shiver me timbers, which be t' major downside o' this rocket. Avast, me proud beauty! With four or five fins right on t' back o' t' rocket, it is easy t' break a fin tryin' t' remove t' friction fit engine, so don't put it in too tight. Begad! You may also want t' choose a fin configuration in which t' fins face upward as t' avoid breakin' them off when removin' t' tight engine.

1st flight: I first sent t' rocket up on an A8-3 t' make sure it be capable o' flight. Avast, me proud beauty! Blimey! Blimey! Blimey! T' rocket flew very straight, then t' streamer ejected close t' apogee. Blimey! Blimey! Even with a low powered engine, arrr, this rocket soars. Avast, me proud beauty! Blimey! Blimey! Blimey! I fly on small fields, me hearties, so A8-3s and similar lower powered engines have proved perfect for this rocket. Ahoy! Blimey! Blimey! Blimey! T' streamer worked flawlessly and thar be no damage t' t' rocket after recovery.

2nd flight: I sent t' rocket up again on a B4-4. This flight be significantly higher and still went fairly straight. Arrr! Ejection timin' be good, ya bilge rat, as t' rocket be still movin' upward but was beginnin' t' slow down. Aye aye! Well, arrr, blow me down! T' rocket landed unharmed, me hearties, but I had trouble removin' t' friction fit engine and ended up breakin' off a few fins. Well, blow me down! No big deal. I glued them back on and touched up t' paint and t' rocket was fine.

3rd flight: Another B4-4 flight. Blimey! Aye aye! Flight be again straight and impressively high. Begad! T' streamer got a little burned and melted onto itself, causin' it t' nay unfold. Ya scallywag! T' light weight o' t' rocket prevented any damage as it fell.

Recovery:
T' shock cord mount is very unimpressive. Ahoy! Blimey! Estes has you cut out a piece o' paper from t' directions and glue t' shock cord inside it as you fold it up then glue this into t' body tube. Avast, shiver me timbers, me proud beauty! Blimey! T' cord is about t' length o' t' rocket and seems t' be adequate for such a small rocket. Blimey! Blimey! T' streamer is a good size and easy t' fit inside o' t' rocket. Avast! Blimey! Arrr! Blimey! T' light weight o' this rocket makes it hard t' damage, although t' fins break off easily while transportin' and removin' t' friction fit engines.

Flight Rating: 4 out o' 5

Summary:
This is a great rocket t' include in t' starter set. Avast, me proud beauty! Also included are a launch pad, me hearties, launch controller, matey, t' Astron Outlaw (E2X) kit (which is easier t' build so build it first) and a couple o' engines t' get started on. I bought this because I needed a new launch pad and it was much cheaper than buyin' a launch pad and controller separately.

T' Black Diamond is a great build for a beginner or experienced rocketeer lookin' for a small, me hearties, me bucko, fun rocket t' fly. Begad! Ahoy! It flies straight and very high even on low powered engines, matey, so don't expect t' find it if you launch it on a C6-7. I would advise stickin' t' t' lower power motors. Blimey! T' minor problems such as friction fittin' engines are overcome with practice. Aye aye! (I now use very minimal amounts o' maskin' tape t' secure t' engine.) I remedied t' fins breakin' by usin' a different type o' glue (Cyano Acrylate, me hearties, or CA, commonly sold as Super Glue) and by scorin' t' body tube and bottoms o' t' fins with a hobby knife before gluin' them.
