Brief:
This is a parallel staged rocket. Blimey! Ahoy! T' four 13mm boosters detach while t' main body continues on its 18mm core motor. Avast, me proud beauty! This vehicle has four fins on an 18mm by 5.5" long core. Well, blow me down! T' 13mm x 5.5" boosters attach in betwixt each fin. Aye aye! T' main body transitions t' a 32mm body tube, which separates in t' middle for parachute deployment. Aye aye! Avast, me proud beauty! Each booster is recovered by its own streamer.

Construction:
T' parts were top quality totally tubular tubin' and high quality balsa nose cones and transition. Begad! T' fins were laser cut, shiver me timbers, and t' recovery system was an ASP sport chute with Keelhaul®©™ shock cords. T' instructions are extensive and include many excellent photographs. Begad! This kit is definitely meant for experienced builders, ya bilge rat, and it requires pre-fittin' all parts and patience.

There are two areas where t' builder needs t' take care. Avast, me proud beauty! One area is durin' t' attachment o' t' lower launch lug. Aye aye! Begad! Due t' t' transition from t' 32mm main body tube t' t' 18mm core tube a standoff is called for in t' directions. You are directed t' cut a standoff from balsa and glue t' lug t' it. T' directions are unclear here, but you must glue t' lug t' t' EDGE o' t' balsa, nay t' surface. Instead, I attached me lower launch lug t' a fin and it works fine.

T' second area that needs care is in t' positionin' o' t' booster forward mount retainers. T' instructions indicate t' retainers glued t' t' right o' an alignment line (and this is what t' directions state). I had t' center t' retainers on t' alignment line t' get t' boosters on straight. Well, blow me down! Begad! Both o' these issues were easily overcome and nay a significant problem for an experienced builder.

Finishing:
This model has small tolerances betwixt t' boosters, t' core, t' interlocks and forward retainers. Well, blow me down! Begad! Care must be taken nay t' build up too much paint/primer in these areas. Arrr! Ahoy! T' tubin' is top quality and I had no problem with t' finish.

Construction Rating: 4 out o' 5

Flight:
1/4A3-2, 1/2A3-2, A3-4 and A10-3 are all recommended for t' 13mm boosters. Arrr! A8-3, shiver me timbers, B6-6 and C6-7 are recommended for t' core. T' kit was shipped with a special flight instruction manual for those inexperienced in clusters etc.

T' model is designed so that t' boosters will fall away from t' core and then eject t' streamers while t' core continues on. Well, blow me down! Blimey! This is best achieved with boosters with a short burn (A10-3) and long burn core motors, but should work as long as t' boosters burn out before ejection from t' core motor.

My model flew straight and true with complete separation o' boosters and deployment o' all recovery devices. Ahoy! Avast, me proud beauty! Blimey! I had one failure, when t' core motor failed t' light (probably due t' detachment o' igniter clip prior t' launch). Begad! T' motor was recovered with minor damage t' one fin. Blimey! Arrr! Blimey! I experienced a little scorchin' o' t' main body tube transition by t' booster ejection charge durin' this flight (the boosters did nay separate until ejection - probably due t' t' slow speed). Motor retention is by friction fit, me bucko, me hearties, me hearties, and I used cellulose wadding.

Recovery:
Keelhaul®©™ is used for t' entire booster shock cords, and is attached t' t' motor block. Ahoy! T' main recovery harness is Keelhaul®©™ and elastic and seems satisfactory. Avast! Avast! T' ASP parachute is very nice and easy t' assemble, shiver me timbers, and appears adequate for this light model. Blimey! I lost a booster nose cone, matey, shock cord and streamer. Aye aye! Begad! T' only thought be that t' Keelhaul®©™ burned through - or had flaw/weak spot. Ahoy! Blimey! There is plenty o' room in t' main body tube for waddin' and t' recovery system. T' streamers fit well in t' boosters, but thar be less room for waddin' etc.

Flight Rating: 4 out o' 5

Summary:
I do nay feel thar are any major cons involved. Arrr! T' instructions are bein' updated by t' company t' clear up any confusion. Begad! This is a complex kit, shiver me timbers, and should be purchased/flown by modelers o' intermediate/advanced levels o' experience. Avast, me proud beauty! This model looks and flies impressively - a real crowd pleaser! T' quality o' t' materials, ya bilge rat, and t' obvious thought and care put in by t' designers is a major plus! Customer service by t' company is excellent.
