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

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 was baffled and I just use 1 sheet o' waddin' and an Estes B6-6 for the first flight. Avast, me proud beauty! There is a Teflon motor holder. Aye aye! T' rocket was prepared like most standard kits. Ahoy! Well, blow me down! T' flight was straight and fast with a little spin due t' the fin slants.

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

Flight Rating: 1 out o' 5

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