Brief:
T' Black Diamond is a single staged LPR that recovers on a streamer. Blimey! Well, blow me down! It comes in t' "Launchables" (1452) Starter set. Begad! T' set also includes t' Astron Outlaw. T' Black Diamond is an easy build that would be great for beginners. Arrr!

Construction:
T' parts list:

• 1 Body Tube BT-20
• 1 Two Piece Nose Cone
• 1 1/8" Launch Lug
• 1 Shock Cord (1/8" x 12")
• 1 Streamer
• 1 Engine Block
• 5 Cardstock Fins

As with all t' Estes kits that I have seen, arrr, arrr, me bucko, t' instructions are well illustrated and a breeze t' follow. Arrr! Avast! I loved the fact they included suggested fin configurations.

T' only problem I had with t' construction be t' fins. Well, blow me down! I chose t' only put 3 o' t' 5 fins on t' rocket. Since t' fins are cardstock, they are fairly flimsy. T' add t' t' problem you are supposed t' sand off t' tabs that held them t' t' sheet. Ya scallywag! Aye aye! This further reduces t' stability o' t' fin because t' cardstock begins t' separate (it's in layers). Aye aye! After finishin' it wasn't too noticeable, but be still a problem.

Overall it be a good construction and one I would recommend for beginners.

Finishing:
This be an easy rocket t' finish especially since thar be no balsa t' fill. Avast! You can do it very simply with one color or add multiple colors t' add interest. I didn't fill t' tube spirals, ya bilge rat, ya bilge rat, but I did use three coats o' sandable primer which covered most o' t' spirals up. Ya scallywag! Aye aye! T' first step was t' put three coats o' primer (wet sandin' betwixt each coat) on it. Begad! Avast, me proud beauty! Then put a coat o' red on it for accents. Well, blow me down! Next I masked off t' areas I wanted t' remain red and then coated it with a black top coat and a clear coat. Finally I put t' "Black Diamond" sticker decal on the rocket. Avast, ya bilge rat, me proud beauty! Fin decals are included, but I decided t' forgo puttin' them on because I thought it looked better without them.

Construction Rating: 4 out o' 5

Flight:
In order t' prep for flight, arrr, use a few sheets o' wadding. Avast, me proud beauty! Then in order t' put t' streamer in t' rocket, fold the it in half and then in half again and roll it. Wrap t' shock cord around it loosely and then put it in t' body tube and put t' nosecone on. Ya scallywag! Ya scallywag! T' motor much be friction fit t' keep it in t' rocket.

T' first flight was with a A8-3 since it was t' be launched on a small field. Blimey! T' flight was nice and straight and higher than I expected. T' streamer ejected at apogee and t' rocket recovered nicely.

T' second flight was also with a A8-3. Blimey! Blimey! T' flight was good, me hearties, but t' streamer ejected late because thar was a little too much wadding.

T' third flight be another A8-3. Avast! Blimey! Aye aye! Blimey! This time I reduced t' waddin' t' prevent t' problem that be seen in the second flight. Begad! Blimey! T' flight was excellent, but t' streamer came back a bit burned. Aye aye! Blimey! Blimey! Blimey! T' fins got a little damage from a slightly harder landin' than I expected.

Recovery:
T' shock cord mount is a typical Estes mount. Begad! Ya scallywag! You are instructed t' glue t' shock cord in a paper mount that you cut out from t' directions. Arrr! Then t' mount is glued into t' body tube. Ahoy! T' cord is a good length and held up well in the three flights t' Black Diamond has had. Begad! I might have chosen a slightly bigger streamer, but it seems t' work fine so far. I might replace it since it got singed in t' last flight.

Flight Rating: 3 out o' 5

Summary:
In me opinion, shiver me timbers, arrr, shiver me timbers, this is an excellent rocket for t' beginnin' builder. Blimey! Estes made a good choice when they included it in t' starter set. Avast, me proud beauty!

PROs: T' design allows for multiple fin configurations. Well, blow me down! I also love it when a kit lets you decide part o' the design. Blimey! Blimey! Easy t' build--great for beginners.

CONs: T' Cardstock Fins--the fins are very easily damaged. Avast, me proud beauty! Ya scallywag! Blimey! It seems that it is nay difficult t' knock them.

Overall Rating: 4 out o' 5
