Brief:
An Angular, matey, 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, ya bilge rat, shiver me timbers, but it is imperative that you read them thoroughly, ya bilge rat, a couple o' times. Ya scallywag! T' parts were laser cut from a plywood. Avast, me bucko, me proud beauty! 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. Begad! So I had t' scrape t' wood, dry fit, and glue again. Begad! Blimey! Taking your time is a must. Avast! T' nose cone be t' most difficult part. Well, blow me down! Bendin' the wood t' shape and holdin' it thar be a trick. Ahoy! I used CA and a few rubber bands. Avast!

Finishing:
There was really no finishin' needed, me hearties, I just used a clear coat, 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. Ya scallywag! Arrr! There is a Teflon motor holder. Begad! Ya scallywag! T' rocket be 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. Ahoy! Begad! I felt it may be short, me bucko, but I built this stock. Aye aye! At apogee thar be no 'chute. Blimey! Avast, me proud beauty! I lost sight o' it comin' down, me bucko, but a crack recovery crew found it. T' 'chute never deployed. I looked as if the ejection charge blew past t' motor, ya bilge rat, shiver me timbers, due t' t' square shape. Blimey! Aye aye!

Flight Rating: 1 out o' 5

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