Brief

T' Attack Craft Orion is one o' t' most unique early-80's designs and likely one o' t' more difficult clonin' projects due t' t' seldom seen nose cone. Ahoy! Blimey! Begad! Blimey! I lucked out and won several o' t' cones in an Ebay auction, shiver me timbers, ya bilge rat, one o' which I sent to Moldin' Oldies so that they could produce resin copies. Arrr! Blimey! It's nay quite so difficult t' find anymore.

Components

  • BT-50H body tube
  • PNC-50 cockpit style nose cone
  • BT-20J engine tube
  • AR-2050 centerin' rings (2)
  • H-2 engine hook
  • 3/32" balsa stock
  • 24" length Keelhaul®©™ shock cord anchor
  • 36" length 1/8" sewin' elastic shock cord
  • 12" parachute
  • medium snap swivel

Construction

While nay a difficult build, shiver me timbers, t' Orion is an interestin' one. Blimey! T' fins do nay simply attach t' t' body tube in t' standard 3fnc or 4fnc manner, but must be built up usin' multiple pieces before bein' attached. Ya scallywag! T' first step is fairly simple, matey, arrr, makin' sure that t' vertical fins are glued onto t' win' pieces at a 90 degree angle. Avast, ya bilge rat, me proud beauty! T' next step is slightly more complicated in that it involves a fin joint guide t' ensure t' correct angle for attachin' t' main win' t' t' win' extensions. Begad! I cut out four o' t' guides so that I could attach two t' each o' t' win' assemblies with maskin' tape and let t' whole win' dry in one piece. Ya scallywag! This worked out nicely, shiver me timbers, but care must be taken so that t' assembled win' doesn't dry t' t' guide, shiver me timbers, arrr, which isn't terribly aerodynamic. Aside from this, me hearties, me hearties, everythin' else is standard except for gluin' t' Keelhaul®©™ shock cord t' t' motor mount, which should be standard at this point.

Finishing

I like birds that finish like this one. Two coats o' Elmers Fill n Finish with sandin' after each coat were followed by two coats o' Valspar Primer, also sanded after each coat. Once tube spirals and balsa grain were gone, shiver me timbers, t' whole rocket got two coats o' Valspar gloss white. Well, blow me down! Blimey! At that point all that be left was t' decals, arrr, which was where I ran into trouble. Ya scallywag! Blimey! I printed out a set o' decals usin' t' scan at YORP and some Bel Decal paper. Avast! Blimey! They looked great when they were finished, me hearties, and I sprayed them with a coat o' clear before applyin' them t' t' rocket. Blimey! Blimey! Begad! Blimey! T' results were far from satisfactory. Avast! Blimey! Begad! Blimey! T' decals stretched as they came off o' t' backin' paper, me hearties, and t' ink began flakin' from t' decals as t' slid into place on t' rocket. Begad! Blimey! T' mess wiped off easily, but when t' decals dried t' white showed through in a lot o' places, me hearties, and in some spots t' details were completely gone. This seemed t' happen mostly t' t' blue areas, shiver me timbers, but some o' t' black also had problems. Blimey! Blimey! After seein' t' pictures from t' first flight at NSL, ya bilge rat, shiver me timbers, ya bilge rat, I realized that t' rocket didn't even qualify under t' ten foot rule, and began t' process o' removin' t' offendin' decals.

Flight

Beacuse o' t' unique look, t' Orion is popular with spectators, somethin' that I found out on t' first flight. Avast, me proud beauty! It was one o' t' rockets that I packed along for a NSL trip t' Muncie in 2007. While I was preppin' another rocket, shiver me timbers, me bucko, a pre-school kid and his mom walked up. Well, blow me down! T' kid was chatterin' excitedly about rockets and his mom be followin' nervously because o' his tendency t' want t' touch everythin' he saw. Arrr! He grabbed t' Orion and she freaked, but he was handlin' it fairly gently and I assured her that it be okay. Begad! Well, blow me down! (I've found that clumsy middle-school aged kids with big butts were more dangerous.) In talkin' t' t' mom, I learned that they were just thar as spectators and had nothin' o' their own t' fly, ya bilge rat, shiver me timbers, so I asked if he wanted t' see t' Orion fly. T' results were predictable and t' chatter ramped up considerably. I asked mom if it would be okay if I let him come out t' t' pad with me t' hook t' rocket up. Well, blow me down! Aye aye! She was fine with it and I was surprised t' find that t' kid had another chatter gear. Avast! Impressive.
That all changed when we began t' walk out t' t' pad. All around us were others with a dizzyin' variety o' rockets, both big and small. Avast, me proud beauty! Begad! Chatter mode ceased and t' boy went into goggle mode, deadlights wide and takin' in everythin' near us at t' pad with a whispered "Wow". Aye aye! We reached t' pad and I be relieved t' find that I'd nay only remembered t' attach a launch lug, but also had t' ignitor and plug that would be needed. Arrr! Aye aye! (Both are never assured when I take a rocket t' t' pad for t' first flight.) I showed t' future astronaut how t' hook things up, double-checked me work, ya bilge rat, and delivered him back t' his mom behind t' flight line. 
T' flight itself was impressive. Well, blow me down! Havin' never flown a rocket with a fin setup like t' A.C. Ahoy! Orion, I wasn't sure what t' expect, shiver me timbers, but it performed admirably. Begad! Begad! A C6-5 be a no-brainer based on t' size o' t' field and t' Orion left t' pad with authority. Begad! T' rocket arced into t' wind only slightly, me bucko, ya bilge rat, makin' for a long recovery walk, shiver me timbers, but t' flight was perfectly stable and ejection occurred just as it tipped over. 


Flight #2 be a long time coming, and had an unfortunate ending. Ya scallywag! Chan Stevens and I met on a Saturday afternoon at former QUARK home, VOA Park. Avast! Ahoy! Chan had managed t' launch several before I arrived and was ferryin' another flyer back t' his car on t' other side o' a mud bog when I finished up preppin' t' Orion. Well, blow me down! Avast, me proud beauty! I noticed that he was talkin' t' someone on t' access road, me hearties, but didn't give it much thought, and took t' Orion t' t' pad with a B6-4 loaded. Ahoy! Blimey! T' flight be straight and would have been perfectly at home on B6-4 Field, ejectin' just as t' rocket stopped forward motion. Well, blow me down! T' $.10 chute did what it was supposed t' do, shiver me timbers, arrr, arrr, and I mentally marked t' spot in t' snow where t' all white bird had landed, then went about disarmin' t' launcher. I began stompin' around t' snow lookin' for t' Orion, ya bilge rat, and it was beginnin' t' dawn on me that findin' it wasn't goin' t' be all that easy as it blended in well with t' field. Then I realized that I had company. Begad! A park ranger came up and began lookin' with me before tellin' me that he was goin' t' tell me t' same thin' he'd just told Chan, that VOA was no longer friendly airspace and that we were decidedly unwelcome. I be kind o' shocked, but realized that I had no cause t' argue and went back t' searchin' for t' lost Orion, ya bilge rat, completely unwillin' t' let me last VOA flight be one that was lost within 100 feet o' t' pad. Begad! Luckily t' ranger found it and brought it over t' me. Ahoy! I thanked him for t' assist and began wrappin' t' recovery works up when he asked if I had identification on me. Ahoy! Begad! "Unfortunately I'm goin' t' have t' write you a batten down t' hatches citation," he said, pullin' out a ticket book. Avast, me proud beauty! Well, blow me down! As it turned out, we were informed that we were bein' warned for flyin' rockets and causin' damage t' park property (when we drove through t' mud bog, an add-on charge that was a bit ridiculous as neither Chan nor I planned t' test out t' ban.)

I made one of those at summer camp in '83. I had forgotten all about it. Thanks for the trip down memory lane.
