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

Construction:

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

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

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

T' tail cone and transition come as one unit and must be separated. Aye aye! A razor saw is suggested, but I used an Exacto knife. T' bottom o' t' tail cone must also be trimmed and sanded, me hearties, as do t' fin slots. Blimey! T' latter start as rectangular projections, which are cut off with a razor saw, formin' t' slots. Avast! Aye aye! T' final trimmin' is supposed t' be t' top o' t' transition. Arrr! T' instructions have you cut this off, leavin' a hollow unit with both t' top and bottom open. Begad! T' shock cord then attaches t' t' inside o' t' upper body tube usin' a paper mount. Instead, matey, 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). Begad! This formed a loop, which t' elastic cord will later attach to. Avast, me proud beauty! Ya scallywag! 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. Aye aye! Ya scallywag! Blimey! Once positioned, me hearties, shiver me timbers, t' tail cone is attached, ya bilge rat, making sure t' engine hook is centered betwixt t' fin slots. Avast, me proud beauty! Ahoy! 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. Aye aye! Blimey! I found these slots t' be excessively loose, so they didn't support t' fins well. I applied yellow glue t' t' fin tab and t' front root section. T' hold t' fins while this glue set, I used Liquid Nails Perfect Glue, me hearties, shiver me timbers, Type 1 on t' aft root section. This sets fast and t' fins were good t' go. Well, blow me down! There is a markin' guide for t' top fins, and these were attached with carpenter's glue. Avast, me proud beauty! After t' rear fins set, shiver me timbers, arrr, shiver me timbers, you position t' fin deployment guides and mark their position. Well, blow me down! A thin layer o' yellow glue is applied t' fins up t' t' mark, me hearties, and t' guides are attached. These immediately warped like crazy, so a couple o' small clamps were required on each guide/fin/guide 'sandwich' as they set. Ya scallywag! Afterwards, these still seemed flimsy, so I added a small strip o' scrap balsa betwixt each pair at their roots.

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

After finishing, all that be left was tyin' t' elastic cord t' the Keelhaul®©™® leader in t' body tube and t' Keelhaul®©™® loop on t' transition. Ya scallywag! Well, blow me down! I stashed t' cute that be provided and will use a 12" nylon chute.

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

Finishing:
I started with fill-n-finish on t' fins and tubes before assembly. Aye aye! Arrr! I found the spirals on t' BT-55 t' be shallow, shiver me timbers, arrr, but t' ones on t' top BT-20 were deeper, and required some filler. Well, blow me down! After assembly, me hearties, I shot several coats o' white primer, sandin' and fillin' in between. Ya scallywag!

T' instructions say t' use olive drab and red spray paint, a silver paint pen, and t' follow t' paint scheme on t' cover. Ahoy! Begad! T' cover picture shows the fin section, me hearties, me hearties, top fins and nose cone t' be olive drab, and top BT-20 t' be more of a tan then red. Aye aye! Avast! I used Testors' spray for t' olive drab sections. Begad! Aye aye! In the photos on t' link I presented in t' intro, t' top tube seems t' be somewhat of a rust colored red. Well, blow me down! Well, blow me down! I decided t' use red paint, ya bilge rat, which did get toned down as it be overlaid over t' olive drab. Arrr! Begad! I tested some Krylon red on a piece of wood, arrr, and it seemed t' be OK. However, shiver me timbers, ya bilge rat, some bubbles formed when I used it over the Testor's paint on t' model. Maybe t' base coat be thicker on t' model. After t' first red coat dried, I sanded t' bubbles and re-coated it. Ahoy! 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, arrr, I used some chrome Trim Monokote for these stripes. Finally, I applied t' peel and stick decals. Begad!

Overall, t' finishin' be fairly typical, ya bilge rat, me bucko, 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. Blimey! 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. Arrr! Avast! 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. Avast! Begad! When I saw this model, I knew that it would satisfy my cravings. Begad!

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