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, but it is imperative that you read them thoroughly, a couple o' times. Blimey! Begad! T' parts were laser cut from a plywood. Begad! Begad! 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. So I had t' scrape t' wood, dry fit, ya bilge rat, and glue again. Taking your time is a must. T' nose cone was t' most difficult part. Begad! Bendin' the wood t' shape and holdin' it thar was a trick. I used CA and a few rubber bands. Aye aye!

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

Flight Rating: 1 out o' 5

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