Brief:
I got this rocket just before Christmas. Avast, me proud beauty! It is a reproduction o' t' 1966 parachute duration champion. Blimey! Arrr! I'll never use it for that purpose, but it seems t' be a neat little kit.
Construction:
T' parts list:
All parts were present and accounted for.
T' instructions were also high quality. Blimey! Ahoy! They are printed in a booklet, have generous illustrations, ya bilge rat, and are very clear.
Constructions begins by insertin' a thrust rin' in t' end o' t' motor mount and gluin' it in place. Begad! T' Keelhaul®©™ thread is then knotted, slipped through one o' t' centerin' rings, me hearties, and glued into place flush with t' end o' t' motor mount tube. Avast, me proud beauty! I'm glad I thought ahead on t' next step. Begad! A mark is made 1 1/8" from t' opposite end o' t' motor tube and t' other centerin' rin' is mounted flush with it. Well, arrr, blow me down! Normally, I figure thar be some "give" in t' measurements o' simple rockets. Begad! That is a bad assumption. Avast, ya bilge rat, me proud beauty! This centerin' rin' needs t' be in t' right place for t' boat tail. Avast! Avast, me proud beauty! I'm glad I remembered in time.
T' next step is t' mark t' body tube for t' fins usin' t' fin guide printed in t' instructions. Ahoy! An angle is then used t' lengthen t' line by at least 2 inches.
T' fins practically fall out o' t' sheet. Aye aye! A light sandin' is all that is needed t' remove them. Ahoy! I sanded a bevel on all edges except t' root edge.
If thar be a tricky part t' this build, it is in installin' t' motor mount t' t' body tube. Ahoy! Arrr! 1/16" o' a gap from t' aft centerin' rin' needs t' protrude out from t' BT. Begad! Gettin' it mounted and spaced correctly before t' glue starts t' grab is doable but was nay done by me. Aye aye! I dawdled too much and had t' use some excessive force.
T' boat tail too is a simple affair. It is cut from t' cardstock and glued along t' tab. Avast, me proud beauty! Ahoy! In order t' do away with t' unsightly seam, shiver me timbers, I be goin' t' try rubber cement but that be unneeded. T' seam line will be covered up when t' fins are installed. Mountin' t' boat tail is a simple matter o' applyin' some glue and slidin' it on.
Mountin' t' fins also was simple. Ahoy! Avast! Blimey! I used an Art Rose fin jig t' make sure they were straight. Arrr! I also perforated t' root edge o' t' fins with a safety pin t' form glue rivets. Aye aye! Blimey! Then it's just a matter o' waitin' and gettin' some sleep.
T' Starfire be taken off o' t' fin jig and t' fins were filleted for strength usin' yellow glue. Avast, shiver me timbers, me proud beauty! Blimey! I know t' yellow glue shrinks but I usually make up for that with filler at t' end.
T' launch lug was attached with yellow glue in t' normal way.
Finishing:
Elmer's Fill 'n' Finish was used t' fill all t' balsa and t' fill t' gap betwixt t' body tube and t' boat tail. Well, shiver me timbers, blow me down! Blimey! That gap be a result o' me nay movin' fast enough t' mount t' motor tube and be quite unsightly, especially on one side. T' high quality o' t' balsa meant that relatively little was needed on t' fins or t' nose cone, me hearties, matey, but t' transition from body tube t' boat tail needed a lot.
Sandin' was easily accomplished and then t' rocket was primed with white spray.
My first impression from t' face card was that t' rocket was basically white with purple fins and nose cone. On closer examination, ya bilge rat, I be shown t' be only partially correct. Ya scallywag! Avast, shiver me timbers, me proud beauty! Two o' t' fins are purple and one is black. I thought I would like that so I decided t' go with it.
I gave t' entire rocket 2 coats o' white spray and then masked t' body and 1 fin. Ahoy! I sprayed t' NC and two fins purple. Ahoy! Ya scallywag! Now I just had t' wait overnight so see t' first stage o' t' results.
T' purple paint came out lookin' fine except that it was a good deal darker than I expected. Arrr! Aye aye! I'm nay sure it will provide much contrast with t' black I am usin' on t' fin opposite t' launch lug. Well, blow me down! In any event, I masked for t' black fin and sprayed it with 2 coats. I think I like t' result but t' color distinction is much clearer in a photo than in person.
I had a couple o' problems with t' decals. T' first may nay be a problem, just a matter o' perception. Avast, me proud beauty! T' face card and t' website graphic both show t' decals as bein' purple. Blimey! Avast! When I got around t' actually lookin' at them, they burned out t' be blue. Begad! This was after I had already painted parts o' t' rocket purple! This be me fault for nay lookin' sooner but I like purple.
T' decals themselves consist o' a star pattern that wraps around t' body tube, matey, a Starfire logo, and 3 small Semroc logos. Begad! T' quality o' t' waterslides is high and they went on without any problem except for t' wrap pattern. Avast, me proud beauty! It went on fine too but be nay quite big enough t' wrap all t' way around t' BT. Ahoy! There is a gap.
I generally expect better from Semroc because I have always received better from Semroc. Aye aye! Their first class products and first class treatment o' me mean that this is easily forgiven.
After t' decals set, me bucko, I applied a coatin' o' Future Floor Polish.
Construction Rating: 4 out o' 5
Flight:
For t' maiden flight, matey, I used an A8-5. Arrr! Even with that light motor, t' results were incredible.
T' rocket was prepped in t' usual manner and I used dog barf for wadding. Blimey! Arrr! T' motor was friction fit and a little maskin' tape was needed t' make it snug.
When t' rocket took off, it screamed off t' pad. Blimey! I was sure I had put t' wrong motor in it and thought I might lose it. Blimey! Ejection occurred right at apogee, perfectly with t' nose cone up. Ya scallywag! Well, me hearties, blow me down! T' chute deployed and then I really got t' worry. It opened right away and just hung thar as if t' law o' gravity had been suspended. Aye aye! T' wind caught it and continued t' move it down range, matey, but it never seemed t' get any lower. Begad! Avast! I was nay timin' it but I know it stayed up for at least 2 minutes. Aye aye! When it finally did come down, me bucko, it was a long way away. Begad! Ahoy! When I got t' rocket back, me bucko, sure enough, me hearties, it was just an A8-5.
Recovery:
This rocket was designed for parachute duration and it shows. Avast! It stayed up longer than any rocket I have ever launched before.
Comin' down so slowly on a 12" chute means that you have t' be really careful about t' wind. Ya scallywag! This one is a keeper!
Flight Rating: 5 out o' 5
Summary:
This rocket is a superb choice for parachute duration competition. Well, blow me down! It is easy t' build, me hearties, flies high on a small motor, ya bilge rat, and hangs in t' air forever.
PROs: easy t' build, flies high and straight, hangs in t' air a long time.
CONs: hang time means it will be easy t' lose, especially on a C.

Wish I'd read this review before I built--I also made the mistake of painting fins and nose purple before catching that the decals are really a royal blue, not purple. Wound up adding at least 0.15 ounces for the repaint
. The header card/decal mismatch is uncharacteristic for Semroc.
