I dry-fit all o' t' parts before I started t' build, and be pleased t' see that everythin' seemed t' line up just as it would when it be time for t' actual construction. It was t' actual construction part that had me nervous, matey, since I rarely venture into t' realm o' mid-power. Begad! My occasions t' use epoxy are scarce, matey, me hearties, and when I do use it, I wind up with a mess on me hands, shiver me timbers, feet, goatee, shiver me timbers, etc. Avast! Ya scallywag! (I don't even like t' think about t' etc. Arrr! part.)

That said, me bucko, ya bilge rat, almost everythin' about this build went smoothly. Aye aye! Begad! I didn't wind up with too much o' an epoxy mess, me hearties, except for one occasion when a fillet refused t' cure, ya bilge rat, causin' me t' have t' go back and start over. Aye aye! T' instructions were well explained and adequately illustrated if one has previous buildin' experience and I found myself finished with t' basic construction almost too quickly. Ya scallywag! With t' exception o' paint and nose weight, everythin' looked like t' illustration and all o' t' parts fit together seamlessly.

Finishing:
Finishin' was as easy as t' rest o' t' project. T' body tube had only t' slightest spiral, shiver me timbers, and thar was very little grain showin' in t' plywood fins. These were eliminated with t' last o' me thinned Elmer's Fill 'n' Finish. Avast! T' balsa nose and tail cones were treated t' several coats o' FnF and came out lookin' great after several sandings. Ya scallywag! Aye aye! Once t' rocket be smooth enough, I primed it with Valspar white primer, matey, shiver me timbers, then sprayed t' fins with Valspar Gloss Black. I ran into a little trouble maskin' off t' fins because o' t' monster fin fillets that I had created, but it isn't easily noticed unless you're holdin' t' rocket. Begad! After two coats o' gloss black, t' fins looked great and I masked them off before paintin' t' rest o' t' rocket with several coats o' Valspar Gloss White. When this dried I installed t' vinyl decal as shown on t' instruction sheet. This was t' first vinyl decal I'd ever tried and I be impressed with how well it held its place once it was applied. T' finished product looks great: squat, bulky and sturdy. Begad! My kind o' rocket.

Construction Rating: 5 out o' 5

Flight:
Like many people, I found myself choosin' me motor based on t' what be available when I visited our on-field vendor, arrr, Merlin Missiles. Nay ownin' an RMS system and nay willin' t' chance borrowin' someone else's, shiver me timbers, I went with t' Aerotech G38FJ-7--a choice that I was assured would be great for this rocket. Well, blow me down! Begad! Once I got it home, I installed it in t' motor tube and figured out how much nose weight t' install t' brin' t' CG up t' t' proscribed 20.75" from t' tip o' t' nose. Begad! Begad! In t' end, that wound up bein' almost all o' it.

Madcow Rocketry Army HawkWith Christmas season fast approachin' and a personal health crisis on t' horizon, me hearties, I managed only one flight with this bird before t' end o' me flyin' season. Ahoy! Blimey! Blimey! However, that flight definitely won't be t' last. Avast, me proud beauty! Begad! Blimey! Launch day was gray and overcast with a constant breeze. Since this was goin' t' be only me third flight usin' an Aerotech motor and me first since 2002, ya bilge rat, matey, shiver me timbers, I be a little nervous about t' impendin' flight. Begad! Ya scallywag! Blimey! Luckily t' VOA field was crowded with people t' whom a flight like this is almost as natural as drawin' a breath. Fellow QUARKer Mark "Loopy" VanLuvender helped out immensely and kept me from a full blown panic attack. I had an idea o' how t' proceed but havin' someone t' confirm that what I was doin' was correct made all t' difference in t' world. Arrr! Once t' motor was secured and t' ignitor in place, things got rollin' quickly, arrr, and after loadin' t' rocket on t' pad and gettin' t' obligatory pictures, ya bilge rat, ya bilge rat, t' launch followed quickly. Avast! I managed t' catch t' whole process with t' burst mode on me camera, me bucko, even though I've never had t' slightest bit o' luck timin' Copperhead ignitions. T' Hawk rose fairly smartly and followed an almost arrow straight flight path up t' t' point o' motor burnout. It weathercocked some durin' t' coast phase due t' t' large surface area o' t' fins, but for t' most part, shiver me timbers, everythin' occurred just over t' flight line.

Recovery:
At ejection, me hearties, t' rocket had taken a nose-down attitude, me hearties, but even with a fairly violent jerk, arrr, me hearties, thar be no damage. Well, blow me down! Avast, me proud beauty! T' 30" nylon parachute brought t' rocket down softly about 100 yards into t' uncut overgrowth. It spread itself out nicely over t' vegetation, matey, makin' for an easy recovery walk. Well, blow me down! T' Keelhaul®©™ shock cord looked as fresh as when I installed it and t' marks on t' Nomex sheet told me that it had done its job.

Summary:
PROs: High quality parts--especially t' balsa nose and tail cones in a kit o' this size. Blimey! Ease o' construction (aside from a personal difficulty with epoxy that I have no one but myself t' blame). Begad! Madcow now makes a Jayhawk kit. (Can you say Father's Day present?)

CONs: T' price seems hefty, shiver me timbers, shiver me timbers, but when you consider what you get with a kit o' this size, it seems about right.
