inflight_blue-bird-zeroBrief:
This is a single stage, three fin rocket with a parachute recovery

Construction:
T' kit comes in a sturdy transparent bag, me hearties, with a header card printed in three colors (which, conveniently, ya bilge rat, means that t' picture o' t' rocket on t' card is in full color). Begad! T' body o' t' rocket is comprised o' two body tubes of glassine-coated kraft paper. Ahoy! There is no payload section. Avast! There are three laser-cut balsa fins, me hearties, shiver me timbers, with three tiny "auxiliary" fins above and parallel t' t' primaries. Ya scallywag! T' fins are already removed at t' factory from the balsa sheetin' and included in their own individual baggie. They, as well as t' nose cone, are o' a very fine-grain balsa. Begad! There were no dents in t' nose cone. Well, blow me down! T' nose cone, matey, screw eye and shock cords are individually bagged, as is the motor mount assembly. T' centerin' rings for t' motor mount are made o' an unknown, shiver me timbers, shiver me timbers, rigid substance (perhaps lightweight plastic or some sort o' dense foam with a flat black coating) but were as sturdy as balsa and definitely more sturdy than paper. Blimey! Begad! An 18 mm cardboard ring, intended t' be used as a motor block and a typical engine hook, are included. Ahoy! Avast! T' shock cord is comprised o' Keelhaul®©™® cord, me hearties, attached t' t' motor mount, me hearties, which is long enough t' actually extend a few inches further than t' length o' the rocket. Ya scallywag! Aye aye! Attached t' that is an elastic shock cord. T' nose cone is balsa, ya bilge rat, attached t' t' shock cord with a screw eye. T' parachute is a Hartle Engineerin' 20-inch Thermal Rider chute. T' decals are water-slide type. Ya scallywag! T' large "Blue Bird Zero" decal comes in its own bag with some sort o' protective, arrr, arrr, waxy sheet coverin' t' lettering. T' smaller decals are also bagged.

T' Blue Bird Zero is firmly a Skill Level 2 kit, in that one has t' assemble t' parachute (a Hartle Engineering Thermal Rider parachute kit) and align t' auxiliary fins with t' primaries. Well, ya bilge rat, blow me down! There are no "gotchas" in the assembly. Arrr! Ya scallywag! T' instructions are in logical order. Well, blow me down! T' motor mount assembly is first in t' instructions. Aye aye! T' motor block is glued flush with t' top o' t' motor mount tube. Arrr! T' above-mentioned motor mount centerin' rings worked well with Elmer's Glue-All® (used throughout t' build) which makes me think that they are made o' high-density foam or some derivative o' paper. T' engine hook is nay attached t' t' motor mount by t' typical plastic ring; instead one cuts out a printed strip of paper from t' last page o' t' instructions and glues that around t' engine hook. Ya scallywag! On t' last page o' the instructions, ya bilge rat, thar be t' standard printed tube markin' guide which one has t' cut out and tape around t' tube. There is also a printed tri-fold shock cord attachment, if one chooses t' attach t' shock cord by this method although such is nay described in t' instructions. Well, blow me down! I used t' time-tested door-frame method t' lengthen t' pencil marks I made on either side o' t' tube markin' guide; I had t' go back and lengthen t' pencil lines further, though, because I had forgotten about t' auxiliary fins! Fortunately, me bucko, I caught this before I had glued t' primary fins onto t' body tube. T' instructions show how t' cut t' included launch lug in half as well as where t' glue t' resultin' two lugs onto the rocket. Avast! There is a view-from-above, smaller-than-scale drawin' in t' instructions showin' how t' attach t' fins at 120 degree angles from each other. Aye aye! I lengthened t' lines representin' t' fins in t' drawin' t' full scale. Before pressin' t' fins on, I let t' glue dry for a few minutes first; then placed t' body tube on top o' t' drawin' I had modified and used line-of-sight t' press t' fins on at t' correct angles. After screwin' t' screw eye in and out of the nose cone, I dropped some glue into t' resultin' hole, and screwed t' screw eye back in. Blimey! Aye aye! T' Hartle chute material is already cut out t' a hexagon shape; one merely has t' apply t' adhesive reinforcin' rings t' both sides o' t' corners o' t' chute, ya bilge rat, and cut t' included thread into 3 equal-length pieces. Avast! Ya scallywag! A few knots later, ya bilge rat, the assembly is done!

Finishing:
I rounded t' leadin' edges o' t' fins. Ahoy! Well, blow me down! I used 3 coats o' Sig sandin' sealer on t' primary fins (and t' nose cone), sandin' with 400 grit sandpaper betwixt coats, me bucko, before gluing the fins on t' body tube. Avast, me proud beauty! After completin' assembly, me hearties, I sprayed t' entire rocket with three coats o' Kilz primer, again sandin' betwixt coats with 400 grit. Avast! This completely covered t' balsa grain and t' spirals in t' body tube (which were shallow t' begin with). Blimey! T' balsa grain o' t' auxiliary fins barely showed upon close inspection; but since these are covered by decals, shiver me timbers, that was satisfactory t' me (besides, me hearties, ya bilge rat, arrr, sandin' such tiny fins would have driven me crazy!). Arrr! Begad! In retrospect, I think I'll try another coat or two o' Kilz on me future balsa rocket components, skip t' sandin' sealer and see if I can cover t' grain that way.

Bein' a cheapskate, matey, matey, I checked t' compatability o' t' paint I already had, ya bilge rat, rather than goin' out first t' buy all Krylon products. Aye aye! Well, blow me down! I had Design Master Larkspur Blue® (which me daughter had chosen for one o' her rockets) and Quick Color white® (99 cents from Home Depot) on me shelf, me bucko, so I sprayed them over Kilz on a spare piece o' body tube. Aye aye! Blimey! After drying, I coated these paints with Krylon gloss clear®, which, matey, arrr, again, I had on me shelf. Ahoy! Well, blow me down! I also tested t' Krylon clear on a corner o' decal sheetin' which I cut off from the decal sheet included with t' kit. There were no devastatin' reactions betwixt these paints. Ahoy! I sprayed t' Quick Color white® on t' bottom half o' t' rocket, matey, then masked it off with newspaper and Frog green tape t' spray t' top half with Larkspur Blue. Begad! Begad! After removin' t' newspaper, I found that some o' t' printin' had come off on t' white paint; so I sprayed one more coat o' white over it.

T' decals were t' best with which I've ever worked! They were thin enough t' glide over curved surfaces, but thick enough nay t' break. Well, blow me down! They practically slid themselves into place! A few nudges with me finger, and they were done!

One historical note: I've always been somewhat bothered by t' combination o' English text ("Blue Bird Zero") and WWII German markings. Ahoy! (I'm strange that way!). Begad! I briefly considered makin' me own decal with a German translation o' "Blue Bird Zero;" instead I decided that this rocket was from an "alternate timeline" in which t' Germans and British were allies durin' WWII. Avast! Accordingly, I added Sir Oswald Mosley's lightning-bolt logo t' t' center o' t' wreath carried by t' German eagle. (Google t' word "Mosley" if you're interested; he would have been t' obvious choice for Prime Minister durin' a German/British alliance. Well, arrr, blow me down! But I digress...).

I didn't have a chance t' clear-coat t' rocket until I got t' t' field. Blimey! Fortunately, t' Krylon clear dries fast.

inflight_blue-bird-zero_allenginegoFlight:
I launched t' Blue Bird Zero three times on November 8. Avast, me proud beauty! Ahoy! I only used recommended motors. Aye aye! T' maiden flight occurred on a B4-2, followed by flights on a B6-4 and a C6-5. T' chutes deployed at or slightly after apogee on all three flights. Arrr! I've read reviews o' scratch-built, me hearties, matey, upsized versions o' this rocket and t' flight characteristics o' my rocket seem similar. It doesn't catapult off t' pad (at least with t' motors I used) but accelerates smoothly, matey, with minimal weather-cocking. Arrr! It's such a pretty rocket, I don't intend t' push it t' t' limit; so a C6-5 is as powerful as I'll use. Begad! It probably went 800 or 900 ft. Begad! on that motor as close as I can estimate.

Recovery:
T' Thermal Rider chute feels slightly slick, doesn't stick t' itself, me hearties, arrr, and rolls/packs easily. Ya scallywag! (They're so good, I ordered a 5-pack o' these chute kits, shiver me timbers, me hearties, o' assorted sizes, me hearties, for use in me other rockets!).T' parachute be t' perfect size for this rocket in terms o' descent rate and wind-drift. Begad! One primary fin was loosened after t' third flight, me hearties, but I attribute this t' t' very thin fillets o' Glue-All which I used. Avast! I added another fillet when I got home, and it's fixed.

Flight Rating: 5 out o' 5

Summary:
It's taken me 30-plus years; but I think I've finally learned how t' build a rocket accordin' t' t' instructions and achieve a paint-job which satisfies me! Accordingly, me bucko, it's appropriate that I honed me skills on this kit, which dates from t' mid-1970s when I first got into this hobby. T' me, me Blue Bird Zero is a display piece. It's nay a high-performance bird; but that's O.K., because I don't want t' lose it. Aye aye! It's pretty; it's made o' high quality materials; and it's reliable. Ahoy! I've thoroughly enjoyed buildin' and flyin' this simple, ya bilge rat, arrr, but satisfying, rocket. Aye aye! If this kit is representative o' other Inflight products, shiver me timbers, I'll definitely be shoppin' with this company again!
