Brief:
An Angular, wooden Airframe, me hearties, 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, arrr, arrr, a couple o' times. T' parts were laser cut from a plywood. It is not especially clear how some pieces are formed or attached so do a lot o' dry fitting. Begad! Avast, me proud beauty! Blimey! T' fit o' t' wood changed when t' white glue was added. Ya scallywag! This caused the wood t' swell. Ahoy! Blimey! So I had t' scrape t' wood, arrr, matey, dry fit, and glue again. Arrr! Ahoy! Blimey! Taking your time is a must. T' nose cone was t' most difficult part. Aye aye! Bendin' the wood t' shape and holdin' it thar was a trick. Begad! Blimey! I used CA and a few rubber bands. Avast, me proud beauty! Arrr! Blimey!

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

Construction Rating: 3 out o' 5

Flight:
T' kit be baffled and I just use 1 sheet o' waddin' and an Estes B6-6 for the first flight. Blimey! There is a Teflon motor holder. Aye aye! Ahoy! 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. Aye aye! I felt it may be short, but I built this stock. At apogee thar was no 'chute. Arrr! Avast! I lost sight o' it comin' down, but a crack recovery crew found it. Begad! T' 'chute never deployed. Begad! I looked as if the ejection charge blew past t' motor, me hearties, due t' t' square shape. Begad!

Flight Rating: 1 out o' 5

Summary:
This was a very challengin' kit t' build. Avast! T' damage be too much t' repair. 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! Ya scallywag!
