QModeling WAC CorporalBrief:
Mid power scale model upscaled from t' Estes WAC Corporal.

Construction:
T' model is based on t' BT-60 and has a 24mm 'E' length engine mount which makes t' kit over 28 inches tall. Ahoy! T' nose cone is injection molded o' a soft plastic with a laser cut wooden plug that also serves as a screw eye mount. Begad! The fins, ya bilge rat, TTW fin mount braces, me bucko, me bucko, shiver me timbers, and fuel transfer conduit/tunnel are all laser cut balsa. Aye aye! T' top centerin' rin' is laser cut wood, me bucko, and t' bottom rin' is heavy laser cut cardstock. Aye aye! Included is a 5 piece laser cut jig that combines fin sandin' unit, me hearties, and a fuel transfer conduit shape pattern. Arrr!

First off, ya bilge rat, I was pleased with t' quality o' t' parts, many o' which are produced 'in house' at Q Modeling. Begad! T' nose cone is crisply molded, requiring only minor finish sanding, and t' 3 light balsa fins and other laser cut parts fit perfectly. Ya scallywag! T' engine hook is a hefty 1/8" wide and is o' heavier gauge than those in most kits. Aye aye! It is also long enough t' hold nay only the motor, me hearties, me bucko, but also t' engine block. Ya scallywag! (I make them this way when I bend me own hooks, me hearties, so I am very impressed.) T' shock chord is a 9' piece o' heavy duty Keelhaul®©™®, and is securely mounted t' t' top o' t' engine tube comin' through t' top centerin' ring.

Despite t' beveled fins and conduit, t' kit is a solid skill level two in regards t' assembly. Arrr! I am impressed by t' 18(!) pages o' historical info, general rocketry modelin' tips, great illustrations, matey, paintin' instructions (three pages alone), shiver me timbers, launch tips, NARRRRR safety code, me hearties, and even instructions to build a 24mm spacer t' fly t' rocket on a D engine. Blimey! Oh yeah, me hearties, shiver me timbers, they also tell you, in very detailed and descriptive terms, how t' build t' kit. Begad! The instructions are clear and often point out common mistakes so that you can avoid them. Arrr! It is obvious that t' gang at Q Modelin' know their rockets. Aye aye! One thin' I really like is that each assembly section has a estimated time so that you can decide when t' stop for t' night. Blimey!

T' parts all go together smoothly, thanks t' precise laser cutting, and clear instructions. On t' first night, shiver me timbers, I assembled and installed t' motor mount with integral TTW fin mounts. Aye aye! T' structure is strong and surprisingly light. Well, blow me down! I was pleased t' see t' foil lined engine mount tube as this kit is beggin' for AT power!! (F21?) T' next night I assembled, ya bilge rat, shiver me timbers, installed, and sanded the fuel conduit and assembled t' nose cone. Aye aye! Ya scallywag! I am now in t' process o' fin sandin' and t' included fin sandin' jig prevents this from bein' a nightmare although it does take some time.

As an aside, I am someone who finds it almost impossible t' leave a design alone. Well, blow me down! Begad! Blimey! I change engine mounts, ya bilge rat, arrr, recovery mounts, etc. Avast! on almost every kit I build, however, arrr, me hearties, I am pleased t' say that t' only change I will be makin' to this kit is t' add 1/4" elastic t' t' stock Keelhaul®©™®-shock chord. T' kit contains 9' o' heavy duty Keelhaul®©™®, but I just like havin' t' extra sprin' o' some elastic. Ahoy!

I only needed standard model rocket tools and supplies t' assemble this kit: X-acto knife, matey, me hearties, sandpaper, Aliphatic Resin glue (yellow glue), medium CA, a pencil and a ruler.

Finishing:
T' rocket is nay yet finished. Avast, me proud beauty! However, me hearties, t' straightforward 3FNC design, plastic nose cone and three pages o' finishin' instructions should make finishin' a breeze.

Construction Rating: 5 out o' 5

Flight:
T' model has nay yet flown. Avast, me proud beauty! T' manufacturer advises t' followin' approximate flight altitudes: 500’ D12-3, matey, ya bilge rat, me bucko, 850’ E9-4. Ahoy! Ahoy! Motor retention is via a heavy duty motor hook. Begad! After flyin' with t' E9. Ahoy! I plan on tryin' some AT E and F motors. Ya scallywag!

With t' TTW design, me hearties, I expect a straight flight.

Recovery:
T' model has nay yet flown. T' recovery system is every bit as you expect from Top Flight Recovery: very light and strong. It includes a Top Flight Recovery 30" Octagon, Thin Mil, Ripstop Nylon Parachute with sewn in 24" Nylon shroud lines, and a Nomex® Heat Shield. Blimey!

Summary:
I be pleased with this kit in just about every way. Begad! T' directions were clear and t' laser cut parts made assembly enjoyable. Avast, me proud beauty! Well, blow me down! T' sandin' jig is a great idea, shiver me timbers, makin' sandin' actually palatable. Aye aye! Aye aye! Due t' it's good looks and simple, ya bilge rat, low power style construction, me bucko, ya bilge rat, I would recommend this kit for anyone who would like to try mid power. Arrr!

    Brief: Relatively tiny for the "Mega" line of Estes upscales, this WAC is a fine looking scale kit and great flyer. An excellent kit in every way even though at $50 list, scale builders on a budget might consider the ASP 24mm version (listing for $20). Construction: I ordered this kit online (actually won it on eBay) and the kit arrived Priority Mail 3 days later. ...

Nice models but quite inaccurate The real WAC corporal is not white. It's yellow and there are no bevels on the fins of the real thing.

Guest A.H. is correct that the original WAC Corporal was yellow. Blame Estes Industries for starting the idea that it was white. However, the original WACC clearly did indeed have beveled fins (or at least a shape very close to a bevel). Look at the original photos and Peter Always drawings at http://www.jcrocket.com/waccorporal.shtml

Followup: Several months ago, QModeling started shipping the MRS-WACC with an 18-inch parachute instead of the 30-inch. The new chute is perfectly sized for this kit.

I have built two of the WAC's and used the bevel on both. Upon examination of photos from White Sands it seems that there is either a prolonged misconception regarding fin section, or the section changed from a more utilitarian bevel to a more elegant shape in the course of successive rounds. The link below clearly shows a double curved root section. http://www.jcrocket.com/images/waccorporal/02-037-004.jpg
