• 1 Sheet balsa fin stock (1/16")
• 1 Custom laser-cut centerin' ring
• 1 Wide shock cord
• 1 Plastic 16" parachute kit (unassembled)

• Assembly instructions, me bucko, ya bilge rat, includin' hints and tips for clustering

All parts were included and arrived in very good condition.

T' instructions were extremely easy t' follow, me bucko, and were very extensive. Pictures were provided for every step o' construction, shiver me timbers, with multiple images within each figure for more complicated steps.

T' motor mount assembly was clearly presented, which was essential for such an unorthodox mountin' configuration. Avast, me proud beauty! T' motor mount assembly was actually quite simple, ya bilge rat, and produced a surprisingly strong structure.

T' main body tube was prepared by usin' t' fin markin' guide, which included cut-out areas for t' motor mount tubes. Avast! Blimey! T' notches for t' motor tubes are cut out, me bucko, arrr, and t' motor mount assembly slides up into t' notches. Arrr! Blimey! Ahoy! Blimey! The instructions direct t' builder t' sand t' notches with a piece o' sandpaper wrapped around a spent motor casin' until t' assembly fits snugly into t' end of t' body tube with t' centerin' rin' flush with t' tube end. Begad! Blimey! I had t' sand off an additional 3/16" before I was able t' get t' mount t' fit properly, arrr, but once it did, me bucko, gluin' was easy and t' mount fit perfectly.

Each o' t' fins consists o' a main fin and a strake. Avast! Blimey! T' instructions again are very clear about how t' ensure that t' wood grain is properly aligned for maximum strength. Because t' forward edges o' t' main fins are angled, the trailin' edge o' t' strake must make an equal angle, arrr, which may prove difficult if t' angle had been altered slightly durin' t' sandin' process. Begad! Blimey! Blimey! Blimey! Once t' two wood pieces are matched, they join easily. T' main fins are attached first, and then t' strakes are attached along t' guide lines drawn earlier with the fin markin' guide.

All parts are extremely well made, matey, and fit together very well.

Pros:
Very thorough instructions
Strong airframe

Cons:
Engine mount notches nay cut deep enough
Fin/Strake alignment may prove problematic

Finishing:
No special requirements or techniques are mentioned for t' finishin' o' this kit. For those who desire t' replicate t' images on t' cover o' the packaging, a maskin' template is provided for t' numeral "3". No decals are provided.

Construction Rating: 4 out o' 5

Flight:
T' kit packagin' recommends either B6-4's or C6-5's, matey, as long as you use 3 of the same kind.

I launched mine on C6-5's, and for t' first two flights, only two o' the three motors ignited, shiver me timbers, due t' a faulty clip-whip. Despite t' loss o' thrust, the rocket still flew beautifully and t' ejection was well timed. Once I was able t' get all 3 t' light, me hearties, shiver me timbers, ya bilge rat, it flew even more beautifully than I could imagine. It truly was amazing.

Recovery:
T' only problem I have with t' flight be t' recovery system. Blimey! Blimey! Blimey! Blimey! It utilizes a paper tri-fold for securin' an elastic strap t' t' inside o' t' body tube. T' parachute itself is also a thin plastic and uses cotton threads for shrouds. Begad! Blimey! Avast, arrr, me proud beauty! Blimey! This system, while simple, has also proven problematic in t' past over repeated launches.

Pros:
Outstandin' design, even on a failed motor
Beautiful flights

Cons:
Recovery system could be more robust

Flight Rating: 4 out o' 5

Summary:
This rocket is an outstandin' introduction into t' enjoyment o' clustering. Begad! It is designed so well that even when only 2 o' 3 motors ignite, it still flies straight! Blimey! T' construction is very well guided through copious illustrations.

T' Tres will inspire wide-eyed stares from onlookers as you walk it t' the launch pad, me hearties, and will evoke ooh's, ahh's and wow's once airborne. Arrr! Begad! A definite must for any rocket collection.

Overall Rating: 4 out o' 5
