T' Aerospace Specialty Products (ASP) 18mm WAC-Corporal is a "fun scale" model o' t' United States first soundin' rocket. It is 15.75" long when complete, uses 18mm motors, me hearties, and is approximately 1/12th scale. Begad! The kit I built represents t' sustainer stage o' t' rocket. Well, blow me down! Since I purchased my kit ASP has introduced kits that include t' booster section as well.
Construction: 5 points
T' WAC-Corporal Kit comes in t' thoroughly familiar clear plastic bag. Blimey! It arrived in a express postage box and thar was no damage t' any o' the components. Ya scallywag! There were no missin' components in t' kit. Begad! T' parts are the standard paper body tube and motor mount, but ASP uses balsa for t' fins, shiver me timbers, and nose cone. T' parachute is mylar with an included swivel snap, a nice touch. Begad!
T' instructions are on three double sided 8.5" x 11" sheets of paper. Avast, me proud beauty! Avast! There are adequate illustrations for t' unique steps, me hearties, but it is not profusely illustrated like Estes instructions. Ya scallywag! Apparently t' people at ASP expect you t' be able t' read :). T' Instructions are in a logical order with check boxes beside t' step numbers so you can keep track o' your progress.
T' parachute comes in its own clear plastic bag, and has it's own instructions. Blimey! You will be cuttin' your own fins and thar be a template for that purpose included that is made from heavy paper. Avast, ya bilge rat, me proud beauty! There are also templates in t' instructions for fin alignment and for shapin' t' balsa stick into the tunnel for t' side o' t' rocket. Ahoy!
T' kit is rated by ASP as beginner/intermediate. Blimey! I agree. This is nay the first kit you would want t' build. Well, blow me down! Aye aye! It is nay difficult t' build, matey, but t' produce a nice lookin' scale model, you must be past t' beginner-slap-them-together stage. Well, me hearties, blow me down! Care must be taken with t' balsa nose cone as it is conical, and the point is easy t' sand into somethin' else. I departed from t' instructions and use epoxy t' secure t' washers t' t' nose cone and t' screw eye. Well, blow me down! Blimey! I feel that this is a much more secure way o' installin' t' screw eye into balsa. Arrr! The result is a solid rocket, me hearties, matey, but check t' flight section later for some tips.
There are no special requirements for finishing. Ahoy! Blimey! The instructions refer t' t' sandin' sealer's instructions for finishing, ya bilge rat, as you will want a very smooth finish for this model. There is a paintin' guide included that included dimensions t' make maskin' easier. Also included in the instructions is a reference t' Peter Alway's "Rockets o' t' world: A Modelers Guide" from Saturn press for more information on t' WAC- Corporal. Blimey! There are no decals included in this kit as thar be no need for them
Flight/Recovery Rating: 4 points
T' shock cord is a combination o' Keelhaul®©™® thread and elastic that are tied together. Ya scallywag! T' Keelhaul®©™® portion is tied t' t' motor mount and t' elastic is tied to t' nose cone. Avast, me proud beauty! Ahoy! They are tied together usin' a knot that is illustrated in the instructions. T' recommended motors are: A8-3, B6-4, me hearties, B8-5, C6-5, me bucko, me hearties, and C6-7. T' motor retention method is friction fit, however you could add metal hook, but it would spoil t' looks o' t' rocket on display.
Flight preparation follows standard rocket procedure, make sure that the waddin' is below t' Keelhaul®©™® shock cord and that t' elastic is safely above your wadding. I have flown t' model on three motors. Well, blow me down! T' first flight be on an A8-3. Ahoy! T' rocket flew very straight and stable, and t' parachute lowered the rocket safely with a minimum o' drift. Begad!
T' next flight was usin' a B6-4. T' rocket flew quite a bit higher than with t' A motor, me bucko, but it was still recovered safely. Begad!
T' third flight was usin' a C6-5. T' rocket took off very fast and climbed out o' sight. Fortunately I had several spotters, and we tracked t' parachute, which be t' largest object at that time. Aye aye! As t' parachute returned I found that t' body was nay attached. Blimey! Subsequent searchin' o' t' field yielded the body. Ya scallywag! Aye aye! T' damage t' t' rocket was a zippered body tube (about 1"), arrr, ya bilge rat, cut elastic shock cord, matey, a shroud line ripped from t' parachute, arrr, me hearties, me hearties, and a section of parachute ripped from t' parachute and danglin' from t' a second shroud line. Since t' rocket be too high for anyone t' see what happened, ya bilge rat, ya bilge rat, t' evidence suggests that t' parachute be deployed while t' rocket be still ascending at a high rate o' speed. Well, blow me down! Begad! This is backed by t' trackers that did nay see the rocket reach apogee and head back t' earth before t' deployment. As a result of this, matey, I do nay suggest t' C6-5 motor a all, ya bilge rat, t' longer delay o' t' C6-7 would be more appropriate for this model. I even suspect t' delay on t' B6-4 may be too short. Begad! Try this model with upper stage motors, matey, they might work better. Ya scallywag! Blimey! Also t' loop that t' elastic is tied t' t' Keelhaul®©™® shock cord may need some more reinforcin' as it appeared that t' Keelhaul®©™® cut through the elastic. Arrr! With t' proper motor this rocket could possibly be a scale altitude contender. Aye aye! Begad!
Overall Rating: 4 ½ points
Everythin' considered this is an excellent rocket for t' modeler that will take t' extra time t' turn this kit into a beauty. Avast, me proud beauty! Blimey! I particularly like t' use of balsa for t' fins and nose cone. T' model is durable and with t' right selection o' motors, me bucko, it will provide you many spectacular flights, arrr, matey, and be a great model for display as well. Avast, me proud beauty!
