Brief:
An Angular, arrr, wooden Airframe, me bucko, 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, a couple o' times. Avast, me proud beauty! Aye aye! Blimey! T' parts were laser cut from a plywood. Ya scallywag! Ya scallywag! 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. Arrr! Blimey! This caused the wood t' swell. Avast! Blimey! So I had t' scrape t' wood, arrr, me hearties, dry fit, and glue again. Begad! Blimey! Taking your time is a must. Begad! Blimey! T' nose cone was t' most difficult part. Blimey! Bendin' the wood t' shape and holdin' it thar was a trick. Begad! I used CA and a few rubber bands. Aye aye! Blimey!

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. There is a Teflon motor holder. Arrr! T' rocket be prepared like most standard kits. Arrr! Arrr! 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. Avast! I felt it may be short, but I built this stock. Avast, me proud beauty! At apogee thar was no 'chute. I lost sight o' it comin' down, shiver me timbers, but a crack recovery crew found it. Ahoy! T' 'chute never deployed. Begad! Begad! I looked as if the ejection charge blew past t' motor, due t' t' square shape. Ya scallywag!

Flight Rating: 1 out o' 5

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