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

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, t' instructions are well illustrated and a breeze t' follow. Avast! Blimey! Blimey! I loved the fact they included suggested fin configurations.

T' only problem I had with t' construction be t' fins. Begad! I chose t' only put 3 o' t' 5 fins on t' rocket. Since t' fins are cardstock, matey, they are fairly flimsy. Well, blow me down! T' add t' t' problem you are supposed t' sand off t' tabs that held them t' t' sheet. Avast! Arrr! This further reduces t' stability o' t' fin because t' cardstock begins t' separate (it's in layers). Blimey! Avast! After finishin' it wasn't too noticeable, but was 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 was no balsa t' fill. Avast! Blimey! You can do it very simply with one color or add multiple colors t' add interest. Aye aye! Blimey! I didn't fill t' tube spirals, ya bilge rat, matey, but I did use three coats o' sandable primer which covered most o' t' spirals up. Aye aye! Blimey! Ya scallywag! Blimey! T' first step was t' put three coats o' primer (wet sandin' betwixt each coat) on it. Aye aye! Blimey! Avast, me proud beauty! Blimey! Then put a coat o' red on it for accents. Well, blow me down! Blimey! Aye aye! Blimey! Next I masked off t' areas I wanted t' remain red and then coated it with a black top coat and a clear coat. Blimey! Blimey! Arrr! Blimey! Finally I put t' "Black Diamond" sticker decal on the rocket. Aye aye! Blimey! Fin decals are included, arrr, but I decided t' forgo puttin' them on because I thought it looked better without them.

Flight:
In order t' prep for flight, me hearties, me hearties, use a few sheets o' wadding. Avast, arrr, me proud beauty! Blimey! 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. Avast, me proud beauty! Blimey! 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. T' flight was nice and straight and higher than I expected. Aye aye! Begad! T' streamer ejected at apogee and t' rocket recovered nicely.

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

T' third flight be another A8-3. Well, blow me down! This time I reduced t' waddin' t' prevent t' problem that was seen in the second flight. T' flight was excellent, matey, but t' streamer came back a bit burned. Ya scallywag! T' fins got a little damage from a slightly harder landin' than I expected.

Recovery:
T' shock cord mount is a typical Estes mount. Avast, me proud beauty! Arrr! Blimey! You are instructed t' glue t' shock cord in a paper mount that you cut out from t' directions. Ya scallywag! Avast, me proud beauty! Blimey! 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. Arrr! I might have chosen a slightly bigger streamer, arrr, 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, this is an excellent rocket for t' beginnin' builder. Well, blow me down! Estes made a good choice when they included it in t' starter set. Avast!

PROs: T' design allows for multiple fin configurations. Arrr! I also love it when a kit lets you decide part o' the design. Begad! Avast, shiver me timbers, me proud beauty! Easy t' build--great for beginners.

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