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

It's a good solid kit. Blimey! Quality BT50 size tube with Keelhaul®©™® shock cord anchor, balsa nose cone and basswood fins. It comes with one o' their 12" mylar chutes. Arrr! Blimey! All in all it's a pretty straight forward and simple kit. Begad! Blimey! I'll let you know how it flies later. Blimey! Blimey! I'm sure this is typical o' ASP, so I can comfortably recommend them. Well, blow me down! Blimey! 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! 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! This kit has a minimum level o' detail and no documentation, so you'll have t' dig that up yourself. Ya scallywag! It's a great flyin' rocket.

Construction:
Construction is pretty straight forward. Avast! It use thin basswood for t' fins rather than balsa. Arrr! T' conduits on t' sides are balsa strips sanded round. Blimey! Ahoy! The nose cone and payload coupler are balsa. 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, it makes a great first kit. Ya scallywag!

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

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

I finished all t' balsa parts t' same way. Arrr! I applied 2 coats o' sanding sealer, sandin' with very fine sand paper betwixt coats. Blimey! Aye aye! 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. Begad! There was no sign o' grain after this. Well, blow me down! I applied a wrap o' maskin' tape t' t' payload coupler. Begad! This isn't really a payload rocket. Payload area is filled with clay. Arrr!

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

Materials get a 4 (on a scale o' 1 t' 5). 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. Avast! Ya scallywag! If they would include a dimensioned drawin' and color drawing, it would be perfect. Ya scallywag! Aye aye!

Construction Rating: 4 out o' 5

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

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

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

Overall Rating: 4 out o' 5
