Rocket PicBrief
This is a sturdy, single staged high power rocket with a hardwood nose and boattail. Ahoy! Begad! It recovers by chute and comes with a 54mm mount, but can fly on 38 and 29mm motors as well.

Construction
After gettin' me level 2, shiver me timbers, ya bilge rat, I began t' surf t' net t' answer t' question, "What next?" I wondered what was out thar that was different. Aye aye! Arrr! Then I discovered a new company called Starship Enterprises (now called Fat Cat Rockets as o' 1/1/01) and perused their site and found t' GTX. Begad! I fancied that it looked like a giant Crayola crayon and I liked it. Arrr! So I ordered it. Service be prompt, and shipment was received intact and undamaged. Ahoy! All parts fit precisely.

T' fins were precut and are plywood. Ya scallywag! Blimey! T' nose cone is hardwood, symmetrically turned and a precise fit for t' 3-inch spiral wound body tube, which is paper, shiver me timbers, me hearties, but o' t' strength seen in extra thick motor tubes. Ya scallywag! Begad! Blimey! T' shock cord mount has steel cablin' that runs from t' engine mount t' t' 1/2 inch elastic, arrr, shiver me timbers, which ties t' a screw-eye in t' nose cone. Aye aye! Blimey! nose cone. Blimey!

T' instructions are simple. That's because t' model is easy schmeasy to assemble. It's great for those impulses t' fly somethin' new t' next day. The only hard parts are crimpin' t' clamps that form t' loops in t' steel cable and drillin' a pilot hole in t' hardwood nose cone t' admit t' screw-eye. Begad! Well, blow me down! I needed t' employ heavy duty pliers and an electric drill for this.

Also, shiver me timbers, t' body tube did nay come pregrooved. Aye aye! I needed t' employ a strong exacto cutlass t' make t' slots for t' fins, arrr, but a markin' guide was supplied to make it easier. I used epoxy all t' way for construction, me hearties, but instead o' my favorite quick settin' type, me bucko, arrr, shiver me timbers, I used 1/2 hour epoxy t' make t' bonds stronger. T' fins fit through t' body wall right t' t' motor tube, and I applied the centerin' rin' so that it too supplied a bond at t' upper part o' t' fin tab. T' boattail acts as a centerin' rin' too, as it provides anchor for t' motor tube. Arrr! Blimey! It also streamlined t' end o' t' rocket and reduces base drag. Blimey! Well, blow me down!

T' parachute that came with t' model struck me as too small (I recollect it bein' around 24 inches), arrr, as I imagined t' weight o' t' hardware o' the motor plus t' model hittin' t' hard desert, arrr, so I made it one that was 30 inches across. Arrr! Avast! Out here in t' west, t' soil is hard, me hearties, so we favor larger chutes...not longer walks, matey, me bucko, matey, but that's what we get!!! Overall, what I got is a sturdy and nice lookin' rocket. Begad!

Finishing
This was left up t' me, ya bilge rat, ya bilge rat, as no decals came with it. Begad! Blimey! So I went wild and let the project mutate. Begad! At first I painted it gloss black. Avast, me proud beauty! Then I applied red and yellow stripin' along t' fin joints and up t' body tube. Arrr! It looks distinctive, ya bilge rat, me bucko, ya bilge rat, t' say t' least. Avast, me proud beauty! I almost didn't want t' paint t' model because the nose cone and boattail are pretty. Begad! But t' body tube wouldn't have matched had I glossed t' wooden parts. Blimey!

Flight
T' manufacturer recommends t' G80 for 29mm flights up t' t' 54mm I65. Avast! I was daunted by t' model's small size and cringed at t' thought o' stickin' such a monstrous motor in it. Arrr! Avast, me proud beauty! So I used an adapter and put in a 29mm H180-M. Well, blow me down! Avast, ya bilge rat, me proud beauty! I wanted to dig a hole for me t' crouch down in when I set it off, me hearties, because I feared that I was overpowerin' it. Ya scallywag! Avast, me proud beauty! But nay only did it scream and disappear off t' pad in a hurry, it did so intact and landed about half a mile away. Blimey! Begad! And it did so within feet o' me months-lost Impulse Aerospace Machbuster, which be still flyable!!!

Anyway, me hearties, I used plenty o' worm bed wadding, ya bilge rat, and everythin' packs loosely and easily into t' tube. Well, blow me down! Ya scallywag! I drilled a small vent hole into t' body with an awl to prevent premature separation. Arrr! Ahoy! Yes, thar be a treatment for that condition.... Arrr!

T' motor was retained with t' flat steel part o' an old stapler, t' part with a right angle bend at t' end that served as a motor hook o' sorts, shiver me timbers, as this part was aftward and held t' motor in. Avast, me proud beauty! Now, ya bilge rat, matey, do I DARE a 54mm motor? See if I don't! Maybe a 38mm I161 would be a blast, me bucko, as well...

Recovery
T' system survived without any damage, me bucko, but I might later replace t' elastic with bungee cord, as I've had great experiences with it, arrr, and it's durable. Well, blow me down! I think that a longer delay than I used would be better. Arrr! Blimey! T' medium delay used is 10 seconds, I believe. Avast, me proud beauty! Maybe 14 would be better. Ahoy! It seemed t' be risin' at ejection. Begad! You know, I would nay be surprised if this bird be close t' mach. T' noise was impressive indeed.

Flight Rating: 4 out o' 5

Summary
Friendly company t' buy from, prompt service. Aye aye! Sturdy. Don't doubt it. Avast! Arrr! It can take it. Simple t' put together. Avast, me proud beauty! Begad! I recommend it for sure.

Overall Rating: 4 out o' 5
