Brief:
This a beautiful, ya bilge rat, exquisitely detailed 1/17.5 'Super Sport Scale' model kit o' t' USA's first satellite launch vehicle.

This rocket can be flown usin' either a 29mm motor canister (for F, shiver me timbers, me hearties, G and H motors) or a (4) 24mm cluster canister. Both 'quick change' mounts are interchangeable and secured with a solid retention system. Avast, me proud beauty! Blimey! This is a fun to build, fun t' fly rocket that will definitely get attention at any launch. Avast, me proud beauty! Ahoy! Is this kit for everyone? I would hope so, arrr, but be forewarned this is nay something that you will throw together t' night before a launch. Begad! Begad! True Modeler's Mission Statement starts off with "Our desire is t' brin' t' art o' model rocketry back t' t' roots from whence it came. Aye aye! T' True Modeler's Rocket Kits are designed t' take you back t' a time when model rocketry placed t' emphasis on "modeling."

For more see True Modeler's website site (link on title).

Construction:
T' main body is one very solid 32" long, 4.0" diameter tube. Well, blow me down! Aye aye! The fins are impressively laser cut, matey, me hearties, 'through t' wall' and assembled from 6 pieces into t' 4 solid fins. Blimey! Centerin' rings and motor mounts are all made from aircraft quality plywood and require only a fair amount o' fitting. Ahoy! Ahoy! T' top assembly, with transition, arrr, me bucko, satellite pod and extension 'tip' is recovered through a 'cradled' 18" parachute while t' main body is recovered by a solidly anchored 36" parachute. Arrr!

As impressive as t' photos on TMRK's website were, openin' t' eagerly awaited package (my girlfriend's Christmas gift t' me!) only reinforced my impression that this rocket would smartly become a favorite o' mine. Ya scallywag! All o' the materials (with a few minor concerns, shiver me timbers, noted later) were o' t' highest quality and appropriate for a solid, me bucko, many times t' fly, arrr, medium powered, arrr, highly detailed model rocket. True Modeler clearly put as much effort and thought into t' assembly instructions as they did in t' design and quality of materials o' this kit. Ahoy! A 12 page, clearly written and illustrated 'book' guides you through t' assembly process. Ahoy! Each major subassembly is 'kitted' in it's own package and clearly explained makin' it almost impossible t' make an error.

T' order o' assembly is 1) Booster Assembly, 2) Motor canisters, me bucko, 3) nose assembly, 4) Satellite and Tub, me hearties, 5) Paintin' and decals, and finally, me bucko, 6) Final assembly and flight prep. Begad! Blimey! As TMRK says "you will find this kit nay too difficult t' build, me bucko, but you must follow t' instructions exactly as they are written and in t' order they are written. Avast! Blimey! Upon completion, me bucko, you will have a master piece you'll be proud t' display and fly." I couldn't agree more!

Finishing:
Finishin' this rocket is pretty much a straightforward process for any experienced rocket builder, me bucko, but here I will note three concerns. Begad! First, was the rather light weight 'fishing' snap hook swivel that attaches t' an eyebolt on the transition below t' satellite tub and helps cradle t' nose assembly (like the Estes Saturn V and Mercury Redstone). Avast! Second were t' decals. Avast, me proud beauty! Avast! There are 4 large "UE" letters (it designates t' 29th Redstone booster built, shiver me timbers, me hearties, shiver me timbers, the 2nd and 9th letters o' t' 'Huntsville' Redstone arsenal). Aye aye! Ya scallywag! While I have never been especially adept at decals I did find these especially delicate and brittle. Begad! I managed t' apply only one o' t' 4 satisfactorily. Thirdly, me bucko, were t' 4 antennae on t' nose section. Well, blow me down! Ya scallywag! I found that these were very delicate and I managed t' break 3 o' the 4 (with an assist from me grandson!) durin' finishing. Ya scallywag! Ahoy! Finally, shiver me timbers, me bucko, I dispensed with them entirely. Ya scallywag! T' paintin' scheme is relatively simple and very clearly illustrated.

PicFlight:
I was rather nervous about flyin' this model because it be me first launch at my local club (Sacramento Area Rocketry Group - SARG) and because I had simply liked how this one looked and didn't want t' wreck it. Arrr! Avast! Blimey! I checked all me prep several time and debated whether t' use an F40-4W Aerotech reload or an Aerotech G80-7T. Aye aye! After consultation with a couple o' more experienced members I decided on t' G80. Basically, me bucko, I wanted t' make sure I had plenty o' power and didn't want t' risk a cato due t' faulty reload motor assembly on me part. As I checked in I received more than a few inquiries about t' model and a number of compliments as well. Aye aye! Well, blow me down! Blimey! My first attempt t' load t' rocket on t' launch rod revealed 'sticky' launch lugs - I had obviously gotten paint on t' inside of the lugs. Avast, me proud beauty! Blimey! A little light sandin' solved this. Well, matey, blow me down! Blimey! I'll have t' admit a small case of butterflies as t' countdown reached 'launch' and t' Copperheads lit the motor. Avast! Arrr! Blimey! T' G80 lifted t' "J1JC" smartly off t' rod and STRAIGHT up! It appeared that chute deployment, me bucko, both o' them thankfully, ya bilge rat, occurred exactly at apogee - after a nice coast. In spite o' slight mishap I was very happy with the flight and again received several compliments on t' flight. Avast! Blimey!

Recovery:
T' only problem I experienced occurred durin' chute deployment. Avast, me proud beauty! Blimey! The lightweight snap hook on t' nose section which I noted earlier be pulled apart and instead o' comin' down gently cradle at 45 degrees t' nose section came down straight on t' satellite extension tube which broke. Blimey! Avast, arrr, me proud beauty! TMRK recommends that you don't glue this delicate extension into t' tub assembly so this will be rather easy t' replace and maybe nay install on future flights! Other than this detail t' main shock cord is solidly attached t' a Keelhaul®©™® cord which is eyebolted solidly into t' t' upper plywood centerin' ring. Begad! Both chutes are high quality rip stop nylon solidly shrouded and grommeted. Begad! Only a little mud and t' above noted damage (which TRMK is replacin' at no charge) marred t' otherwise perfect maiden flight o' me TMRK 'J1JC' and it WILL fly again, arrr, often, ya bilge rat, and at me first opportunity. Ya scallywag!

Flight Rating: 4 out o' 5

Summary:
Overall, I could hardly be happier with this kit. Begad! T' detail o' t' rocket requires that several parts be delicate and I am more than happy t' manage those details. Avast! Arrr! Another plus is that Mark and Scott at True Modeler are very helpful whenever needed. Ya scallywag! My experience with this kit would lead me t' highly recommend this TMRK kit and TMRK generally. Ya scallywag! Ahoy!

Just a quick comment on the "UE" lettering and what it means. It was actually the 'serial number' of the flight, with the letters from the word 'HUNTSVILLE' used in place of numbers. Huntsville is 10 characters so, H-1, U-2, N-3, and so on, making 'UE' flight number 21. I may have the letter/number info incorrect, but this is the origin of the lettering.

I built this kit. It is an awesome kit to have. I launched mine on an Aerotech G64-4W reload. It was a picture perfect flight. TMRK makes some really nice kits. Well worth you money.

I flew this kit for the first time on a D12-3 four-by cluster to 250 feet. Beautiful, graceful and satisfying launch. Perfect deployment of the chutes and a nice, easy landing. The only adaptations I made were for a rail launch, and I used West System 90 epoxy to reinforce the main transition paper shroud (turns the paper into FRP wonderfully), the fins and 4" tubes. What a wonderful kit if you like scale and historic replicas - right size, very durable if you build right and a truly nice flyer. I am looking forward to a four-by cluster flight on Aerotech E30 SUs - should be over 1,300 feet!
