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

Finishing:
There was really no finishin' needed, I just used a clear coat, me hearties, 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! Arrr! T' rocket was prepared like most standard kits. Avast! T' flight was 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. I felt it may be short, me hearties, but I built this stock. Well, blow me down! Avast! At apogee thar was no 'chute. Ahoy! Arrr! I lost sight o' it comin' down, me bucko, but a crack recovery crew found it. Begad! Aye aye! T' 'chute never deployed. Ahoy! I looked as if the ejection charge blew past t' motor, due t' t' square shape. Aye aye!

Flight Rating: 1 out o' 5

Summary:
This was a very challengin' kit t' build. Arrr! T' damage was too much t' repair. Avast! If I were t' build this again, matey, me hearties, ya bilge rat, I would find a way t' keep t' gases forward to pressurize t' recovery device.
