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

That said, almost everythin' about this build went smoothly. Begad! Aye aye! I didn't wind up with too much o' an epoxy mess, matey, except for one occasion when a fillet refused t' cure, causin' me t' have t' go back and start over. Avast, me proud beauty! 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. Avast! Aye aye! With t' exception o' paint and nose weight, matey, 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, me bucko, and thar was very little grain showin' in t' plywood fins. Begad! These were eliminated with t' last o' me thinned Elmer's Fill 'n' Finish. Begad! T' balsa nose and tail cones were treated t' several coats o' FnF and came out lookin' great after several sandings. Once t' rocket be smooth enough, me hearties, matey, I primed it with Valspar white primer, 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. Avast! 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. Avast! Aye aye! 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 was impressed with how well it held its place once it was applied. T' finished product looks great: squat, bulky and sturdy. Ya scallywag! My kind o' rocket.

Construction Rating: 5 out o' 5

Flight:
Like many people, I found myself choosin' me motor based on t' what was available when I visited our on-field vendor, Merlin Missiles. Blimey! Begad! Nay ownin' an RMS system and nay willin' t' chance borrowin' someone else's, I went with t' Aerotech G38FJ-7--a choice that I be assured would be great for this rocket. 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. Ya scallywag! In t' end, matey, shiver me timbers, me hearties, 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. Aye aye! However, that flight definitely won't be t' last. Ahoy! Launch day be gray and overcast with a constant breeze. Avast, me proud beauty! Arrr! Blimey! Since this be goin' t' be only me third flight usin' an Aerotech motor and me first since 2002, me hearties, I was a little nervous about t' impendin' flight. 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. Ahoy! I had an idea o' how t' proceed but havin' someone t' confirm that what I was doin' be correct made all t' difference in t' world. Begad! Blimey! Once t' motor was secured and t' ignitor in place, things got rollin' quickly, and after loadin' t' rocket on t' pad and gettin' t' obligatory pictures, ya bilge rat, t' launch followed quickly. I managed t' catch t' whole process with t' burst mode on me camera, even though I've never had t' slightest bit o' luck timin' Copperhead ignitions. Begad! T' Hawk rose fairly smartly and followed an almost arrow straight flight path up t' t' point o' motor burnout. Ya scallywag! Blimey! It weathercocked some durin' t' coast phase due t' t' large surface area o' t' fins, matey, shiver me timbers, matey, but for t' most part, everythin' occurred just over t' flight line.

Recovery:
At ejection, t' rocket had taken a nose-down attitude, but even with a fairly violent jerk, thar was no damage. Well, blow me down! Blimey! 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, me bucko, makin' for an easy recovery walk. Aye aye! Blimey! 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. Begad! Ease o' construction (aside from a personal difficulty with epoxy that I have no one but myself t' blame). Ya scallywag! Avast, me proud beauty! Madcow now makes a Jayhawk kit. Blimey! (Can you say Father's Day present?)

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