Rocket PicIntroduction:
Scale model o' t' U.S. Ya scallywag! Army's first guided missile. Begad! I got t' Aerospace Specialty Products catalog by sendin' e-mail t' them. Aye aye! ASP has some really cool products, arrr, especially for NARRRRR people gettin' into competition. It's a basement business, arrr, so don't expect call center answerin' systems and full blown retail convenience. Ahoy! I bought a couple o' Mylar chutes and decided that I'd give one of their kits a try. Blimey!

It's a good solid kit. Begad! Quality BT50 size tube with Keelhaul®©™® shock cord anchor, balsa nose cone and basswood fins. Avast, me proud beauty! Blimey! It comes with one o' their 12" mylar chutes. All in all it's a pretty straight forward and simple kit. Begad! Blimey! Avast! Blimey! I'll let you know how it flies later. Begad! Blimey! I'm sure this is typical o' ASP, me hearties, shiver me timbers, so I can comfortably recommend them. I will definitely buy more stuff from them in t' future.

Quality Scale Kit...
This is a scale model o' t' US Army's first guided ballistic missile. Aye aye! Ya scallywag! The Corporal missile was developed about t' time and by t' same folks who developed t' WAC Corporal soundin' rocket (hence t' name similarity). Begad! Aye aye! This kit has a minimum level o' detail and no documentation, so you'll have t' dig that up yourself. Well, blow me down! It's a great flyin' rocket.

Construction:
Construction is pretty straight forward. It use thin basswood for t' fins rather than balsa. Begad! T' conduits on t' sides are balsa strips sanded round. Arrr! The nose cone and payload coupler are balsa. Avast, me proud beauty! T' decals are t' peel and stick on type. Well, blow me down! If you've spent time buildin' paper and wood models, this will be a snap. Otherwise, me bucko, shiver me timbers, it makes a great first kit.

I started out wrappin' t' body tube and payload section with 1/2 oz fiberglass. Arrr! Blimey! I also glassed t' fins. It resulted in a hard, smooth surface. Ya scallywag! Blimey! I then installed t' motor mount as per t' directions usin' yellow glue. Blimey! Blimey! Here my only objection is a lack o' a motor hook. Avast, me proud beauty! Blimey! T' 18 mm tube is inside a 24 mm tube and t' two tubes are flush, so thar's no way t' apply an external wrap of tape. Aye aye! Blimey! T' only thin' holdin' t' motor in is friction. Aye aye! Blimey! Begad! Blimey! T' payload section/nose cone is quite heavy, ya bilge rat, so this rocket is a good candidate for a drag separation, so you'll want t' coupler t' fit snug too. Be careful as inexperienced people could have drag separation, me bucko, or motor ejection.

I attached t' fins with thickened epoxy. T' reason I used epoxy was I could get a strong bond, matey, but I had some time t' work with it. Avast! I glued a spent motor onto a scrap piece o' cardboard. I placed t' body tube on t' this. motor such that t' fins would just touch t' cardboard. I was hopin' that I could set t' four finned rocket on a flat surface and it wouldn't rock.

I finished all t' balsa parts t' same way. Well, blow me down! I applied 2 coats o' sanding sealer, sandin' with very fine sand paper betwixt coats. Well, blow me down! Avast! Then I mixed some RAKA epoxy with maple flour until it be as thick as very thick syrup. Blimey! I painted this on t' balsa parts. Ahoy! There be no sign o' grain after this. Aye aye! Ahoy! I applied a wrap o' maskin' tape t' t' payload coupler. Arrr! This isn't really a payload rocket. Well, arrr, blow me down! Payload area is filled with clay.

I applied 2 coats o' scratch fillin' primer, me bucko, wet sandin' betwixt coats with very fine sandpaper. Blimey! Finally I applied 3 thin coats o' Krylon White. When this was done I carefully applied t' decals. Well, ya bilge rat, blow me down! Blimey! I'm quite pleased with t' results. Won't win any contests, me hearties, but it looks really nice. Ahoy! Avast! Blimey!

Materials get a 4 (on a scale o' 1 t' 5). Ahoy! Blimey! I deduct a half point for t' lack o' a motor clip and a half point because thar be nay scale data for t' rocket included. Ya scallywag! Blimey! If they would include a dimensioned drawin' and color drawing, me bucko, it would be perfect.

Construction Rating: 4 out o' 5

Flight/Recovery:
I only recommend t' A, me hearties, B and C motors. Well, blow me down! It would handle t' D motors just fine, but it would go very high, very fast and be hard t' track. T' C motor gets it way up there. Avast, me proud beauty! It flies very straight, even in windy conditions. It's fairly heavy for it diameter and fin area, ya bilge rat, so it doesn't tend t' weather cock much. Arrr!

T' supplied parachute is fine, shiver me timbers, in fact I'm kinda in love with t' ASP mylar chutes. Begad! Ya scallywag! I attach a snap swivel from a fishin' supply store and use t' ASP parachute on all me model rockets. That parachute has been through a lot. Well, blow me down! Avast! Get a red one. Well, blow me down!

Flight Rating: 5 out o' 5

Summary:
This is a very pretty rocket. T' value for your loot if fantastic. It flies well, matey, high and straight every time. Aye aye! Blimey! It's large enough that you can just see it a t' end o' a C6-5 boost. Begad! Blimey! Well, blow me down! Blimey! T' take off is nice and slow with t' A motor.

Overall Rating: 4 out o' 5
