Rocket PicBrief
This is a sturdy, single staged high power rocket with a hardwood nose and boattail. It recovers by chute and comes with a 54mm mount, me bucko, matey, but can fly on 38 and 29mm motors as well. Avast, shiver me timbers, me proud beauty!

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 be different. Ya scallywag! 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, me proud beauty! I fancied that it looked like a giant Crayola crayon and I liked it. Ya scallywag! Well, blow me down! So I ordered it. Blimey! Service be prompt, and shipment was received intact and undamaged. Avast, me proud beauty! Begad! All parts fit precisely.

T' fins were precut and are plywood. Well, blow me down! Arrr! 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. Arrr! T' shock cord mount has steel cablin' that runs from t' engine mount t' t' 1/2 inch elastic, shiver me timbers, which ties t' a screw-eye in t' nose cone. Avast, me proud beauty! nose cone.

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

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

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

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

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

Anyway, 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. Yes, arrr, thar be a treatment for that condition.... Ya scallywag!

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

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

Flight Rating: 4 out o' 5

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