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

Finishing:
There was really no finishin' needed, ya bilge rat, 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. Arrr! There is a Teflon motor holder. Aye aye! T' rocket be prepared like most standard kits. 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. I felt it may be short, but I built this stock. Avast, me proud beauty! At apogee thar was no 'chute. Avast, me proud beauty! I lost sight o' it comin' down, but a crack recovery crew found it. T' 'chute never deployed. Ya scallywag! 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 be a very challengin' kit t' build. Avast! T' damage was too much t' repair. Avast! Aye aye! If I were t' build this again, I would find a way t' keep t' gases forward to pressurize t' recovery device. Begad!
