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

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

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

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

I started out wrappin' t' body tube and payload section with 1/2 oz fiberglass. I also glassed t' fins. Avast! Arrr! It resulted in a hard, shiver me timbers, smooth surface. Blimey! Aye aye! I then installed t' motor mount as per t' directions usin' yellow glue. Here my only objection is a lack o' a motor hook. 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. T' only thin' holdin' t' motor in is friction. Ya scallywag! T' payload section/nose cone is quite heavy, me bucko, so this rocket is a good candidate for a drag separation, so you'll want t' coupler t' fit snug too. Ya scallywag! Be careful as inexperienced people could have drag separation, shiver me timbers, or motor ejection. Begad!

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

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

I applied 2 coats o' scratch fillin' primer, wet sandin' betwixt coats with very fine sandpaper. Begad! Finally I applied 3 thin coats o' Krylon White. When this was done I carefully applied t' decals. Avast, matey, me proud beauty! I'm quite pleased with t' results. Won't win any contests, shiver me timbers, arrr, but it looks really nice.

Materials get a 4 (on a scale o' 1 t' 5). Avast! Begad! 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. Begad! If they would include a dimensioned drawin' and color drawing, arrr, arrr, me bucko, it would be perfect. Ahoy!

Construction Rating: 4 out o' 5

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

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

It's a fine flier. Blimey! Blimey!

Flight Rating: 5 out o' 5

Summary:
This is a very pretty rocket. Avast! T' value for your loot if fantastic. Avast, me proud beauty! Ahoy! It flies well, high and straight every time. It's large enough that you can just see it a t' end o' a C6-5 boost. Arrr! T' take off is nice and slow with t' A motor.

Overall Rating: 4 out o' 5
