Brief:
This is a semi-scale model o' t' GBU-24 Paveway III laser guided bomb. It flies on 18mm motors and recovers under a 12" chute. Aye aye! You can find more info on t' actual bomb [here] . Well, blow me down! Blimey!

Construction:

• One BT-55, 10 7/8" long
• Plastic tail cone/adapter (separated durin' construction)
• Two BT-20 tubes, 5" long
• Seamless elliptical plastic nose cone, arrr, BT-20
• Cardstock centerin' rings
• Engine hook
• Engine block
• Mylar retainer rin' for t' engine hook
• Launch lug, matey, me hearties, 1/8"
• Elastic shock cord, matey, 1/8" x 18"
• Assembled 12" plastic chute
• Die cut balsa fins, 3/32"
• Die cut balsa fin protectors, me bucko, 1/16"
• Peel and stick decals
• Endurin' Freedom sticker (not used on model)

T' first step is t' assemble t' motor mount. Ahoy! This is a typical build, and consists o' t' BT-20 motor mount, me bucko, arrr, two centerin' rings, matey, an engine hook, a Mylar retainer for t' hook, matey, and a motor block. I used carpenter's glue as recommended. Before installation in t' main body tube, arrr, ya bilge rat, I epoxied a two-foot section o' Keelhaul®©™® twine onto t' mount, shiver me timbers, shiver me timbers, ya bilge rat, trough t' top ring.

Next, matey, me bucko, arrr, I removed and sanded t' fins, ya bilge rat, and filled them with Fill 'n Finish. T' main fins were fine, but t' protectors, shiver me timbers, me hearties, which attach on either side o' the rear fins, shiver me timbers, me bucko, were very thin and warped badly when exposed t' t' moisture in the Fill 'n Finish. Well, blow me down! Well, blow me down! I pressed these as they dried and they straightened out.

T' tail cone and transition come as one unit and must be separated. Arrr! Begad! A razor saw is suggested, but I used an Exacto knife. Ya scallywag! T' bottom o' t' tail cone must also be trimmed and sanded, me hearties, as do t' fin slots. T' latter start as rectangular projections, which are cut off with a razor saw, ya bilge rat, formin' t' slots. Begad! Aye aye! T' final trimmin' is supposed t' be t' top o' t' transition. T' instructions have you cut this off, me bucko, leavin' a hollow unit with both t' top and bottom open. Arrr! Avast, arrr, me proud beauty! T' shock cord then attaches t' t' inside o' t' upper body tube usin' a paper mount. Instead, I poked a small hole in t' recessed ridge just below t' top o' the transition, fed a loop o' Keelhaul®©™® twine through t' hole and around t' transition (see photo). This formed a loop, which t' elastic cord will later attach to. Begad! A small dab o' 5-minute Epoxy on t' hole and knot holds t' twine in.

T' tail cone is used t' adjust t' depth o' t' motor mount as it is glued into t' main body tube. Blimey! Avast, me proud beauty! Blimey! Once positioned, me hearties, t' tail cone is attached, me hearties, shiver me timbers, making sure t' engine hook is centered betwixt t' fin slots. Begad! Begad! Blimey! I used black rubberized CA in place o' t' recommended plastic cement.

T' lower fins are mounted through t' slots in t' tail cone. Ahoy! Ya scallywag! I found these slots t' be excessively loose, so they didn't support t' fins well. Avast! I applied yellow glue t' t' fin tab and t' front root section. Begad! T' hold t' fins while this glue set, I used Liquid Nails Perfect Glue, arrr, Type 1 on t' aft root section. This sets fast and t' fins were good t' go. Begad! There is a markin' guide for t' top fins, me hearties, and these were attached with carpenter's glue. After t' rear fins set, arrr, ya bilge rat, you position t' fin deployment guides and mark their position. Blimey! A thin layer o' yellow glue is applied t' fins up t' t' mark, shiver me timbers, and t' guides are attached. Begad! These immediately warped like crazy, so a couple o' small clamps were required on each guide/fin/guide 'sandwich' as they set. Afterwards, me bucko, these still seemed flimsy, ya bilge rat, so I added a small strip o' scrap balsa betwixt each pair at their roots.

T' final steps prior t' finishin' be t' launch lug and Fill ' Finish fillets. Ya scallywag! I didn't' glue t' top tube t' t' transition or t' cone until finishin' be complete. When they were connected, shiver me timbers, I again used black CA.

After finishing, arrr, all that was left was tyin' t' elastic cord t' the Keelhaul®©™® leader in t' body tube and t' Keelhaul®©™® loop on t' transition. Aye aye! I stashed t' cute that was provided and will use a 12" nylon chute.

Overall, arrr, I give this build a 3 1/2. Blimey! It all went together easily with the exception o' t' fin deployment guides, which should have been made o' thicker material. Aye aye! Aye aye! T' dimensionin' o' t' fin slots on t' tail cone also wasn't good. Luckily any 'slop' is hidden by those guides. Arrr! Well, blow me down! One thin' that stood out t' me was t' quality o' t' nose cone - it is completely seamless. Aye aye!

Finishing:
I started with fill-n-finish on t' fins and tubes before assembly. Ahoy! I found the spirals on t' BT-55 t' be shallow, shiver me timbers, but t' ones on t' top BT-20 were deeper, and required some filler. Aye aye! Begad! After assembly, me hearties, ya bilge rat, I shot several coats o' white primer, sandin' and fillin' in between. Avast, me proud beauty! Avast, me hearties, me proud beauty!

T' instructions say t' use olive drab and red spray paint, a silver paint pen, me bucko, and t' follow t' paint scheme on t' cover. Avast, me proud beauty! T' cover picture shows the fin section, shiver me timbers, top fins and nose cone t' be olive drab, shiver me timbers, and top BT-20 t' be more of a tan then red. Begad! I used Testors' spray for t' olive drab sections. In the photos on t' link I presented in t' intro, t' top tube seems t' be somewhat of a rust colored red. Ya scallywag! Well, blow me down! I decided t' use red paint, me bucko, which did get toned down as it was overlaid over t' olive drab. Avast, me proud beauty! I tested some Krylon red on a piece of wood, me hearties, and it seemed t' be OK. Begad! However, some bubbles formed when I used it over the Testor's paint on t' model. Begad! Maybe t' base coat was thicker on t' model. After t' first red coat dried, I sanded t' bubbles and re-coated it. This time it covered just fine.

There are silver bands shown at t' base o' t' BT-55 and BT-20 tubes. Instead o' silver paint, I used some chrome Trim Monokote for these stripes. Finally, me bucko, I applied t' peel and stick decals. Arrr! Begad!

Overall, t' finishin' was fairly typical, arrr, however I found t' separation in t' side plates where they extend ahead o' t' main fins made sprayin' a little more difficult than usual. Well, blow me down! I give it a finishin' ratin' o' 4.

Construction Rating: 3 out o' 5

Flight:
I decided t' submit this partial review since I missed t' November launches and may nay be on t' field until spring. I'll provide an update at that time.

Summary:
I saw me first 'bunker buster' rocket over a year ago and have really wanted to build somethin' similar. Begad! Avast, me proud beauty! When I saw this model, I knew that it would satisfy my cravings. Arrr! Well, shiver me timbers, blow me down!

T' model was nay a difficult build, me hearties, and I think a skill level 2 ratin' is about right. Ahoy! Avast! I liked t' plastic parts, me hearties, especially t' nose cone, and think the thru-the-wall fin attachment is great. Aye aye! However, matey, shiver me timbers, t' fit o' t' fins be poor and t' balsa used for t' fin protectors was flimsy. As with t' Cluster Bomb BLU-97B that I just built, me bucko, ya bilge rat, it appears that Estes needs t' pay more attention to quality control. Still, t' rocket be fun t' build and looks *very* cool. Aye aye! Begad!
