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

Construction
After gettin' me level 2, I began t' surf t' net t' answer t' question, "What next?" I wondered what was out thar that was different. Avast! Blimey! 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. Avast! Avast! Blimey! I fancied that it looked like a giant Crayola crayon and I liked it. So I ordered it. Service was prompt, ya bilge rat, and shipment was received intact and undamaged. Ya scallywag! Blimey! All parts fit precisely.

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

T' instructions are simple. Aye aye! That's because t' model is easy schmeasy to assemble. Avast! It's great for those impulses t' fly somethin' new t' next day. Avast, me proud beauty! 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. Avast! I needed t' employ heavy duty pliers and an electric drill for this. Aye aye!

Also, me bucko, t' body tube did nay come pregrooved. Avast! I needed t' employ a strong exacto knife t' make t' slots for t' fins, me hearties, but a markin' guide be supplied to make it easier. Well, blow me down! I used epoxy all t' way for construction, me hearties, but instead o' my favorite quick settin' type, matey, ya bilge rat, matey, I used 1/2 hour epoxy t' make t' bonds stronger. T' fins fit through t' body wall right t' t' motor tube, ya bilge rat, 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, shiver me timbers, as it provides anchor for t' motor tube. It also streamlined t' end o' t' rocket and reduces base drag. Blimey!

T' parachute that came with t' model struck me as too small (I recollect it bein' around 24 inches), as I imagined t' weight o' t' hardware o' the motor plus t' model hittin' t' hard desert, so I made it one that be 30 inches across. Avast, me proud beauty! Out here in t' west, me bucko, t' soil is hard, so we favor larger chutes...not longer walks, ya bilge rat, ya bilge rat, but that's what we get!!! Overall, shiver me timbers, what I got is a sturdy and nice lookin' rocket. Well, me bucko, blow me down!

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

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

Anyway, me bucko, I used plenty o' worm bed wadding, and everythin' packs loosely and easily into t' tube. I drilled a small vent hole into t' body with an awl to prevent premature separation. Avast, me proud beauty! Yes, ya bilge rat, thar be a treatment for that condition.... Avast!

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, me bucko, as this part was aftward and held t' motor in. Begad! Avast, me proud beauty! Now, do I DARE a 54mm motor? See if I don't! Maybe a 38mm I161 would be a blast, me hearties, as well... Begad!

Recovery
T' system survived without any damage, but I might later replace t' elastic with bungee cord, as I've had great experiences with it, and it's durable. Ahoy! I think that a longer delay than I used would be better. Ahoy! T' medium delay used is 10 seconds, I believe. Blimey! Blimey! Maybe 14 would be better. It seemed t' be risin' at ejection. Aye aye! 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, arrr, prompt service. Avast! Sturdy. Begad! Blimey! Don't doubt it. Ahoy! Blimey! It can take it. Blimey! Begad! Simple t' put together. Blimey! Well, blow me down! I recommend it for sure.

Overall Rating: 4 out o' 5
