Brief:
This is a mini engine powered downscale o' t' Centuri ESS Raven contructed out o' cardstock, featurin' streamer recovery. This was one o' me favorite designs o' me younger days that I never got a chance t' build. Avast, me proud beauty! Avast, me proud beauty! T' two plan sheets give you all t' parts needed and then can be assembled usin' t' plan set from Jim Z: http://www.dars.org/jimz/cen5312.htm

Construction:
Components consist o' two plan sheets that should be printed on 65 lb. Arrr! Ahoy! paper. Well, blow me down! (Plan Sheet 1 - 892K; Plan Sheet 2 - 371K) There is a lot o' unprint area on t' sheets and that will be used t' laminate t' parts t' make them sturdier. In addition a 12" length o' 1/8" elastic be used for t' shock cord, a 1" X 10" streamer cut from a plastic tablecloth, me hearties, shiver me timbers, and a small ball o' clay for nose weight..

T' parts were cut out and t' wings, main fins, arrr, arrr, me bucko, stabilizer, ya bilge rat, me bucko, win' support, stabilizer support, landin' gear, ya bilge rat, matey, sensor pod, and scoop were glued onto t' excess cardstock and placed betwixt wax paper on a flat surface under a heavy book until dry.

T' body tubes were pre-rolled by placin' them printed side down on a mouse pad and rollin' a dowel over them until they started t' take shape. Begad! Expended motor casings were used t' roll t' body tubes. Arrr! Ahoy! I rolled t' tube until it just started t' overlap and then spread Elmers white glue over t' exposed tab with a Q-tip and finished rolling. Begad! If you're careful, shiver me timbers, t' edge should just match t' color seam line. Ya scallywag! Place them aside t' dry.

I pre-rolled t' body tube coupler, matey, nose cone shoulder and engine block and placed them inside t' completed tubes t' check for size before gluein' them.

When t' flat parts are dry, cut out t' parts and glue together t' top and bottom win' parts, left and right main fin, matey, arrr, top and bottom stabilizer, shiver me timbers, scoop support and place them back under t' book t' dry.

T' nose cone is formed by rollin' and gluein' t' shroud piece, rollin' and gluin' t' shroud doubler inside, and formin' t' cone section. Avast! Arrr! T' cone section is glued t' t' shroud, linin' up t' printed cockpit, and t' shroud glued t' t' short forward body section and t' nose cone shoulder glued into t' body tube leavin' 3/4 o' t' length outside t' tube.

From this point, ya bilge rat, t' downloaded instructions can be followed. Well, blow me down! Blimey! Make sure t' put a launch lug on before gluin' t' nacelles. Begad! When attachin' t' wings, line up t' pre-printed markings. This model uses an engine block. Blimey! Ahoy! Glue is smeared in t' body tube about 1 1/2" inside t' aft tube with a Q-tip and t' block pushed in with an expended motor until 1/4" is exposed. Aye aye! remove t' motor immediately.

T' prototype required 4 grams o' clay nose weight.

Finishing:
T' finishin' o' this model couldn't be easier. Avast, me proud beauty! Ya scallywag! Everythin' is pre-colored and I used a couple coats o' gloss clear t' seal t' ink.

Flight:
T' model is light enough t' use 1/4A through 'A' 13mm mini engines. Ahoy! Well, me bucko, blow me down! There really is no need t' use A10-3T's in this light a model as t' A3-4T has plenty o' power. Arrr! Begad! I used a 1/2A3-4T for t' first flight. T' motor is a friction fit usin' maskin' tape. Begad! I used two squares o' waddin' but cut each square in half because o' t' small body tube. Avast! T' launch was straight and fast. I almost lost sight o' t' model against t' overcast sky. Blimey! I was able t' pick up t' streamer in t' air for a successful recovery. Avast, me proud beauty! Avast! T' streamer really isn't needed and is thar t' help spot it. Begad! T' second and third flights were repeats o' t' first.

Recovery:
T' streamer probably isn't needed but helps in locatin' t' model both in t' air and on t' ground. Blimey! There is nay a lot o' room in t' body so packin' t' shock cord and streamer must be done carefully.

Summary:
I really enjoyed makin' this. Begad! Avast, arrr, me proud beauty! Blimey! T' model looks a lot like t' full size Raven.

Pro's - good looking, uncommon model. Inexpensive t' make and fly. Well, blow me down! No paintin' except clearcoat.

Con's - small body tube is difficult t' pack.

Other:
This be one o' me first attempts t' recreate some o' t' classic models in a small easy t' handle size.
