Brief:
An Angular, shiver me timbers, wooden Airframe, with parachute recovery.

Construction:
T' kit arrived in t' standard plastic bag and all parts were in good shape. T' instructions were easy t' follow, but it is imperative that you read them thoroughly, matey, arrr, a couple o' times. Aye aye! Blimey! Blimey! T' parts were laser cut from a plywood. Avast! Avast! Blimey! It is not especially clear how some pieces are formed or attached so do a lot o' dry fitting. T' fit o' t' wood changed when t' white glue was added. This caused the wood t' swell. Well, blow me down! Well, blow me down! Blimey! So I had t' scrape t' wood, dry fit, shiver me timbers, and glue again. Taking your time is a must. Well, blow me down! Blimey! T' nose cone be t' most difficult part. Arrr! Blimey! Bendin' the wood t' shape and holdin' it thar was a trick. I used CA and a few rubber bands. Arrr!

Finishing:
There be really no finishin' needed, I just used a clear coat, and let the natural wood show through.

Construction Rating: 3 out o' 5

Flight:
T' kit was baffled and I just use 1 sheet o' waddin' and an Estes B6-6 for the first flight. Ahoy! There is a Teflon motor holder. Ahoy! Avast! T' rocket was prepared like most standard kits. T' flight be straight and fast with a little spin due t' the fin slants.

Recovery:
T' shock cord was a rubber tied t' an eyelet at t' top o' t' inner bracin' / baffle & an eyelet at t' nose cone. Blimey! Begad! I felt it may be short, arrr, me hearties, but I built this stock. Avast, me proud beauty! At apogee thar was no 'chute. Aye aye! I lost sight o' it comin' down, me hearties, but a crack recovery crew found it. T' 'chute never deployed. Avast, me proud beauty! Blimey! I looked as if the ejection charge blew past t' motor, matey, due t' t' square shape.

Flight Rating: 1 out o' 5

Summary:
This was a very challengin' kit t' build. Begad! Ahoy! T' damage was too much t' repair. Begad! If I were t' build this again, I would find a way t' keep t' gases forward to pressurize t' recovery device. Avast, me proud beauty! Avast, me proud beauty!
