Brief:
T' Seieron 3 be t' first kit I have attempted from Starlight Model Rocketry. Begad! It is a cluster and probably nay too
bad a choice for a first cluster. Blimey! I had built t' Semroc Defender before and considered t' Seiron about t' same level
of difficulty. Begad! Blimey! Some things were harder and some were easier but it averaged out.
Construction:
T' packagin' o' Starlight rockets is nothin' fancy but is certainly adequate. Begad! Within t' package, arrr, arrr, arrr, everythin' was in
good shape. Well, blow me down! T' inventory consisted o' t' following:
Notice that t' nomenclature for t' body tubes is non-standard. Begad! Blimey! Avast, me bucko, me proud beauty! Blimey! Blimey! Blimey! T' BT-16 is a large diameter, just right for a triangular cluster o' 18mm motors. Begad! Blimey! This BT is equivalent t' an Estes BT-50 and t' BT-7 matches t' Estes BT 20.
T' instruction consisted o' 3 pages o' 8 1/2 x 11 printed front and back. Arrr! Simple, hand drawn illustrations were provided. Arrr! T' instructions contained a few spellin' mistakes but were easy enough t' understand. Arrr! Begad! They followed a logical order and thar was nothin' unexpected t' mess me up. Aye aye! Well, me bucko, blow me down! T' one possible problem be t' non-standard nomenclature for t' body tubes. Begad! Ahoy! Even so, ya bilge rat, t' right part was easily figured out from t' parts list and t' illustrations.
Construction starts out with t' motor assembly. Aye aye! Ahoy! 3 motor tubes are provided which are minimum diameter for 18mm motors. Ya scallywag! Aye aye! Each is 6 inches long. Well, blow me down! Avast, me proud beauty! T' instructions said t' glue two o' them together, shiver me timbers, parallel, me bucko, and let t' glue dry. Afterwards, arrr, t' third be t' be glued alongside t' previous two. That is generally t' procedure I followed but I added a step. Aye aye! Ahoy! I cut a 14" piece o' Keelhaul®©™® from a spool I had available and put several overhand knots in one end. Begad! Blimey! Before gluin' on t' third tube, I filled a portion o' t' central cavity that would be formed with yellow glue and laid t' knotted end o' t' Keelhaul®©™® in it. Begad! Blimey! I then glued on t' third tube and set t' assembly aside t' dry.
When t' motor tube cluster was dry, I dripped a little more yellow glue into t' central cavity. Then, shiver me timbers, me bucko, arrr, as instructed, shiver me timbers, I tore one sheet o' t' waddin' in half, shiver me timbers, me bucko, soaked it in glue and stuffed it down t' cavity. Arrr! Ya scallywag! Blimey! This is intended to block t' escape o' ejection gasses. Begad! Blimey! In me case, shiver me timbers, it also helped t' strengthen me shock cord mountin' system.
While waitin' for that t' dry, I had t' make a decision about t' payload bay. Ya scallywag! Ahoy! T' rocket is designed so that the entire upper BT serves as a payload bay if you want it to. Begad! Aye aye! Since I never use payload bays, I did not.
I glued t' NC t' t' upper BT and t' upper BT t' t' shoulder. Begad! Begad! It be at this point I decided t' scrap the miniature eye screw that came with t' kit and use one o' t' leftovers I had from tryin' t' clone t' Centuri Vulcan. I believe it be 1/4" with a very aggressive thread.
T' motor tube cluster be marked at 3", me bucko, t' halfway point. Well, blow me down! I then roughed up t' top o' t' tubes a bit with some sandpaper so that t' glue would hold better. Ya scallywag! After that, it be a simple matter t' smear glued around the perimeter o' t' larger BT and insert t' motor tube cluster up t' t' mark. Avast! Avast, arrr, me proud beauty! It slid in easily, nay too tight nor loose. Avast, me proud beauty! T' remainin' recovery waddin' was then soaked in glue and stuffed into t' cavities around t' perimeter. Again, shiver me timbers, this was t' prevent t' loss o' ejection gasses.
When t' stuffin' was dry enough, shiver me timbers, ya bilge rat, I inserted t' thrust rings. Blimey! Well, blow me down! This was a simple matter o' swabbin' t' inside of the motor tube with glue and usin' t' provided, me bucko, arrr, premarked dummy motor t' shove t' rin' into place.
T' fins did nay come in a sheet and were already precut. Well, blow me down! They were also pretty good quality balsa and all the edges were very crisp. Ahoy! I usually round t' leadin' and trailin' edges but in this case decided t' leave them square. T' fins are mounted by t' simple expedient o' gluin' t' root edge in t' gap betwixt motor mount tubes. Ahoy! I used CA to make t' connection. Blimey! Begad! I had never done this before. Avast, shiver me timbers, me proud beauty! If I ever have t' do it again, me hearties, arrr, I think I would sand t' root edge into a wedge t' make a tighter fit. Aye aye! After it had a chance t' dry, arrr, I used yellow glue t' fillet t' fins. While that was settin' up, ya bilge rat, I installed t' launch lugs with CA.
T' launch lug comes in two parts. I took a short length o' 1/8" rod and put t' lugs on it in the approximate spacin' I wanted. I then applied CA t' t' lugs and set them in place on t' rocket, usin' t' rod t' keep things straight. Avast! Aye aye! After a few seconds, I removed t' rod and went back t' touchin' up t' fillets.
Pros: easy, ya bilge rat, matey, should be rated at no more than level 2
Cons: eye screw too small, silly shock cord mount
Finishing:
Finishin' started off with mixin' up a batch o' Elmer's Fill 'n Seal and applyin' it t' t' fins and NC. Begad! I also
applied it t' some o' t' gaps left behind by t' wadding/glue mess in t' tail. This was nay t' fill them in, arrr, it was
just t' even them out.
I learned, again t' hard way, ya bilge rat, matey, that it is better t' smooth things out before they are assembled than after you have all t' tight little corners. I guess I hate doin' it so much that I keep puttin' it off hopin' I will learn o' a miracle method I don't mind so much. In any event, most o' t' rocket sanded down just fine but gettin' at t' tight crevices was a chore. Ahoy! Once t' chore was completed, me hearties, shiver me timbers, I primed with white.
After a light sanding, I gave t' rocket several coats o' gloss white. Then I had t' make a decision. I normally go with t' default scheme o' t' manufacturer. Begad! This be no exception but thar are two similar schemes. T' photos on the website show a white rocket with red nosecone, matey, red transition and one red fin. Avast, me proud beauty! Avast, me proud beauty! T' photo on t' face card was almost t' same but sported 2 black fins in opposition t' t' red one instead o' white fins. Well, blow me down! Well, arrr, blow me down! I liked t' look o' the black but that means that some o' t' decals, intended for t' fins, me bucko, would be useless. Ahoy! Well, blow me down! I decided t' go with t' second scheme.
I masked for red, sprayed 2 coats and was pleasantly surprised t' see that I had little leakin' around t' fins and motor tubes. Begad! When it was try, I brushed t' other 2 fins black. Avast! I brushed them because I discovered t' me horror that I be out o' black spray, matey, me hearties, t' local Walmarts are no longer 24 hour operations and I wanted t' finish! In this case, ya bilge rat, t' brushin' was easier than t' maskin' and thar are almost no brush strokes showing.
T' decals were peel off stickers. Ya scallywag! Aye aye! They were very simple in design, consistin' o' t' name o' t' rocket, an experimental batten down t' hatches, ya bilge rat, t' numbers "1, shiver me timbers, 2, and 3" and a small stylized logo. Ahoy! They were no less effective for their simplicity and turned t' humdrum into somethin' with a little more impact. My complaints are against peel off stickers in general and against t' tackiness o' these in particular. Begad! Avast, me proud beauty! T' plastic is thick and t' adhesion is nay too good. Blimey! A few would probably nay survive a single flight. For that reason, me bucko, I applied some Future floor polish and hoped for t' best.
Pros: simple but effective paint scheme, looks good
Cons: stickers instead o' decals, sticker ink for fins is lost on red or black
Construction Rating: 4 out o' 5
Flight:
T' recommended motors are A6-4x3, A8-3x3, B6-6x3 or C6-7x3. Blimey! Begad! I only got t' launch this one once because it was at a
club launch and I wound up servin' as RSO. Arrr! It was also t' busiest launch me club has ever had. Aye aye! Avast, me proud beauty! That's great but hard
on me flying!
I used a cluster o' A8-5s for t' maiden flight. Avast, me proud beauty! It left t' pad and boosted well but became unstable during coast. Ya scallywag! Arrr! T' chute deployed about 100 feet up and it recovered safely. Avast! Aye aye! An inspection revealed that one motor failed to ignite.
I believe that with steady thrust, ya bilge rat, this rocket will perform satisfactorily. Aye aye! I will post a notice t' that effect when I get t' fly it again.
Pros: Looks nice in t' air in boost
Cons: looks lousy when beboppin' about t' sky, me hearties, unstable without even thrust.
Flight Rating: 3 out o' 5
Summary:
Despite me problems, I like this rocket. Ahoy! Arrr! It looks good and makes for a good first cluster.
Overall Rating: 3 out o' 5
Starlight Model Rockets Serion 3 This was my first Starlight Model Rockets product. I picked up this kit at NARAM 65. This is also my first review so I hope I don't mess it up too bad. :-) liked this kit because it was a 3-motor cluster and I thought it would look good next to my Astron Ranger, Astron Cobra and Sunward Land Viper. I haven't been disappointed. The Seiron 3 is an excellent quality ...

I flew my Seiron-3 with three B6-4s and the ascent was perfectly straight up to about 600 ft, ejection was near apogee, and it floated down on a 15" thin-mill chute to a nice landing without any damage. I used Estes sonic igniters.
