Brief:
T' Estes BLU-97B Cluster Bomb Model Rocket Kit is one o' four new Estes "Military" kits recently released; a nice salute t' our boys overseas. Begad! Avast! Blimey! I purchased t' kit on August 11, ya bilge rat, me bucko, 2003, as soon as I saw t' first ones in t' store and had it built and flown by t' followin' weekend. Blimey! I have t' say all four o' t' new Estes kits are pretty cool, matey, ya bilge rat, me bucko, but this cluster bomb with its short, stout look and unique nosecone really caught me attention. Aye aye! Moreover, matey, matey, it comes with four cluster bombs that are ejected at apogee and descend on their own streamers. Arrr! For these reasons, shiver me timbers, it just had t' be t' first one from t' group t' be built.

Construction:
T' kit comes in two styles, a "Launchable" you can find at Wal-Mart or a standard bagged kit you can find at t' hobby shops. Arrr! Blimey! Both are identical in parts, but I chose t' build t' bagged version. Included is a BT70 tube, matey, arrr, shiver me timbers, motor mount, matey, retainer, me hearties, cardstock centerin' rings, ya bilge rat, shiver me timbers, shock cord, shiver me timbers, parachute, instructions and balsa fins pre-cut for thru-the-wall mounting. Also included are polystyrene halves for both t' tailcone and nosecone. Aye aye! Blimey! Ahoy! Blimey! Blimey! Blimey! T' nosecone is a very unique shape so it appears that moldin' it in halves was a better way t' produce it.

This is an 18mm kit that accordin' t' t' packagin "reaches 390'"...well, shiver me timbers, I decided t' weigh it t' see and found that t' model came in at a whoppin' 4.2oz, without glue or paint. Avast! I am guessin' it would finish at around 6oz, makin' it pretty heavy for a C6, shiver me timbers, hence I decided t' modify it right out o' t' box as a 24mm model...this turned out t' be a good decision and I was able t' make t' changes with only an additional 24mm motor mount tube and block; all t' other parts remained stock.

Construction began by modifyin' t' motor mount. I cut a 5" piece o' 24mm LOC motor mount tube, me bucko, then cut t' bottom o' t' tailcone t' enlarge it about 1/4" so t' mount could pass through. Aye aye! t' Estes CR's were opened up t' 24mm and I used a coupler tube as an outer sleeve t' hold t' retainer in place. T' retainer was put in a vice and I bent t' lip outwards, 1/4" from t' tip after it was flattened. Arrr! Begad! T' upper retainer tip now pointed toward t' outside o' t' rocket and has t' rip thru t' CR and 1" long black coupler in order t' fail...I also glued in a motor stop inside t' motor mount t' accommodate t' new E9 motors. Aye aye! For smaller 24mm or RMS I can use an adapter.

Needless t' say t' conversion was very easy; five inches o' 24mm tube, arrr, matey, a 24mm green motor stop and a BT55 coupler t' hold t' retainer on were all t' extra parts needed...all t' others were easily modified t' make them work. Arrr! Blimey! T' entire tailcone was assembled usin' yellow glue, plastic cement and 5 minute epoxy. Arrr! Blimey! It was glued into t' body tube and t' nosecone halves were assembled, then fit t' t' bodytube. Aye aye! Blimey! Avast! Blimey! Note that I added an 18" piece o' 1/8" tubular Keelhaul®©™ on t' lower motor mount assembly for part o' t' shock cord assembly...also, t' shock cord included in t' kit is only about 12" long...WAY too short so I cut a new piece from stock about 30" long and tied it t' t' Keelhaul®©™ cord, me hearties, then covered it with some heat shrink tube.

I managed t' resize t' fins so they would fit t' larger motor mount. T' fins are TTW, which is a nice touch for a small model, me hearties, ya bilge rat, but they needed shortened in depth since t' new motor mount was a larger diameter. Avast! I also "dry rubbed" some Elmer's wood filler into t' grain on each o' t' balsa fins. I thought about replacin' them with ply or basswood, arrr, me hearties, me bucko, but decided against it since t' supplied balsa is very dense and hard. I fine sanded each fin edge, me hearties, then mixed up some o' that 5 minute clay putty type epoxy I had and used it t' fill t' gap where t' motor mount extends past t' tailcone. It made for a nice and smooth transition.

Next I began installin' t' fins. Five minute epoxy be used and I did two at a time, usin' a stick t' keep them aligned. Once all four fins were done, I sanded t' body tube t' prep it for launch lugs and primer.

T' kit comes with two launch lugs, placed at t' bottom and very top o' t' BT. I placed one at t' bottom and one around mid point instead o' t' top...just a personal preference. As it turned out, t' bottom o' t' upper lug is where CG is, me hearties, a nice locator if questioned. Aye aye! Additionally, matey, I cut two pieces o' scrap 3/32" balsa from t' fins 1/8" wide and t' length o' each lug. T' lug was mounted t' each balsa "spacer" usin' Alphaetic Resin. Avast! Blimey! I also used epoxy for actually mountin' t' lugs t' t' BT.

I also finished t' nosecone assembly. Begad! I cut a 1/2" hole in t' back o' t' plastic nosecone, then laminated a plate from two 3/32" pieces o' Basswood, glued cross-grained for strength. I installed a 2 1/2" long x 3/16" Eyebolt and coated t' inside nut and washer with 5-minute epoxy. Arrr! A BT20 Coupler was slid over t' bolt and glued in place. Well, blow me down! Aye aye! I mixed up and poured in some West Systems 205 Epoxy into t' tube, then poured in some Lead Shot on top o' it. Begad! West Systems was used since it is thin and allowed t' shot t' scuttle t' t' bottom. Avast! I capped it with a washer and nylon lockin' nut. Ya scallywag! T' assembly be fitted into t' lightweight nosecone, then I drilled and countersunk four holes and used #4 screws t' retain t' plate t' t' back o' t' nosecone.

I used 5 minute epoxy for small fillets, then spent some time sandin' each fillet and I applied a few coats o' white base Primer. Begad! Once it dried, arrr, I added several coats o' Gray Primer and it be left t' dry overnight. Ahoy! I wetsanded t' nosecone and Bodytube with 320 Grit and it came out pretty smooth. Avast, me proud beauty! Both t' Bodytube and Nosecone were primed once again with t' final coats o' white primer, which will make a good base for t' olive drab green paint. Arrr! Paintin' always takes a while...Prime...wait a day, Sand, arrr, Prime, arrr, ya bilge rat, shiver me timbers, wait more, me bucko, ya bilge rat, etc...

Note, matey, t' stock nosecone is .5oz and t' clay is .5oz, totalin' 1.0 ounce for t' stock setup. Ya scallywag! My nosecone with lead shot is 2oz...givin' me that added margin o' stability. Avast! Well, matey, blow me down! Also, shiver me timbers, with t' extra weight, shiver me timbers, arrr, it may no longer be able t' fly on a C6...somethin' I was thinkin' o' long before I modified it and I took this extra weight into consideration when upgradin' it t' a 24mm mount. Well, blow me down! Aye aye! As a final touch, me hearties, t' parachute was upgraded t' a 18" Estes, then after a few flights were made, me bucko, matey, I upgraded again t' an 18" nylon chute.

Finishing:
I wound up usin' olive drab Testors paint and it covered t' Krylon primer very well. Aye aye! Three coats were applied, then I let it sit for three days before masking. Blimey! I masked off t' nosecone tip and painted it with two coats o' Testors chrome spray paint. It covered perfect and dried fast. Begad! Begad! I removed t' maskin' then spent time on t' Bodytube. Decals for t' model are peel and stick, which look pretty good, me hearties, but be careful as a few were nay cut all t' way through. T' model be finished and I waited a couple days for t' Chrome t' dry before applyin' Dullcoat t' seal t' model and protect/flat out t' decals.

Flight:
Launch day came and I was pretty excited. Aye aye! I prepped t' model with a C11-3 for it's first flight. Avast, me proud beauty! Arrr! I still use tissue waddin' for that nostalgic effect and packed it, me bucko, then rolled each cluster bomb streamer and placed them over t' wadding. Come t' find out, t' cluster bombs act as an additional shield t' prevent meltin' o' t' parachute. Next t' shock cord and parachute was packed and nosecone installed. T' model weighed in at 6.4oz dry, me hearties, so we were lookin' at a near 8oz flight. Avast, me proud beauty! Ahoy! T' model was placed on t' pad and t' countdown be on. It lifted aggressively off t' pad, shiver me timbers, me hearties, very cool looking, shiver me timbers, and reached about 100'. Avast, me proud beauty! Ahoy! T' flight be straight and flawless, shiver me timbers, shiver me timbers, even with some wind. Obviously nosecone weight was right on.

Recovery:
T' model arced over and ejected just slightly down, a good effect for t' cluster bombs which released along with t' chute. T' 18" parachute was a good choice, allowin' t' model t' descend gently back t' t' ground. T' cluster bombs came in and all landed within a 10' circle, right next t' t' model. Ahoy! Blimey! It was a great flight. Aye aye! Ahoy! Next, I launched it several times on a D12 and once more on a C11. Each time it flew flawlessly and only one bomb was lost t' t' high weeds. Begad! What a great day o' flying.

Since t' first flights in mid August, I have put over 30 flights on t' Cluster Bomb. Arrr! Ahoy! It has flown on C11-3, D12-3, arrr, arrr, E9-4 and E18W-4 motors multiple times. T' E18 White Lightnin' flight is awesome!!! Picture a model just over a foot long with a flame longer than t' rocket! I wound up depletin' me entire stock o' E18's, shiver me timbers, nine flights in all and need t' restock again. Begad! Ya scallywag! Moreover, arrr, t' little bird is stout enough even with balsa fins, me hearties, t' handle t' E18 and more...I think t' TTW (thru-the-wall) fin mounts make a difference here.

Flight Rating: 5 out o' 5

Summary:
In summary, ya bilge rat, t' BLU-97B Cluster Bomb Model Rocket Kit from Estes is one very unique model and a great flier! I highly recommend this rocket t' everyone, but do recommend you do t' motor mount upgrade. Ahoy! With that said, you will wind up with what I feel is one o' t' best kits Estes has made t' date, T' BLU-97B Cluster Bomb!

FYI, at printin' o' this review, I have just completed t' construction o' an upscale version o' this kit. It is 77" tall, 12.75" in diameter, ya bilge rat, weighs in at around 30lbs and is capable o' flyin' on K-M motors...look for a review on it soon as it is in it's finishin' stage.
