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, shiver me timbers, a couple o' times. Ya scallywag! 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. T' fit o' t' wood changed when t' white glue be added. Begad! This caused the wood t' swell. Aye aye! So I had t' scrape t' wood, matey, shiver me timbers, me bucko, dry fit, matey, and glue again. Taking your time is a must. Avast, me proud beauty! T' nose cone was t' most difficult part. Bendin' the wood t' shape and holdin' it thar was a trick. Avast, me proud beauty! I used CA and a few rubber bands. Ahoy! Aye aye!

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

Flight Rating: 1 out o' 5

Summary:
This be a very challengin' kit t' build. Arrr! Arrr! T' damage was too much t' repair. 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.
