Semroc Astronautics Astro-1Brief:
With more and more old rocketeers rediscoverin' t' hobby and Estes seemingly intent on remainin' a shadow o' its former self, arrr, it be only a matter o' time before other, matey, more BAR friendly companies arrived on t' scene t' fill t' void. Ahoy! One o' t' more recent o' these companies is Semroc. Ya scallywag! More "experienced" fliers will recognize t' Semroc name from their brief stint in t' rocketry world 30+ years ago, but it would be a mistake t' think o' them based on this alone. T' new Semroc is a self contained model rocketry history lesson, ya bilge rat, with planned offerings from as far back as Orville Carlisle's 1957 Roc-A-Chute Mark II and from long lost companies like Model Missiles, Flight Systems, Canaroc, shiver me timbers, me bucko, Rocketry Development Corporation, me hearties, Centuri, matey, and their own Semroc products. Blimey! (They even have a token Estes kit, shiver me timbers, t' Sky Hook from t' Astron days.) Like many others, matey, when t' new Semroc lineup o' rockets was announced a few months ago, I smartly put t' Laser X at t' top o' me "can't wait t' build" list. Avast, me proud beauty! While t' Laser X project turned out t' be an enjoyable one that produced a great lookin' rocket (despite me efforts t' t' contrary), I was surprised t' find that I enjoyed buildin' t' Astro-1 quite a bit more. Begad! I had always assumed that t' Astro-1, arrr, a stocky, me bucko, sturdy, arrr, ya bilge rat, 3FNC rocket, me bucko, me hearties, was in t' same ballpark as t' Estes Alpha from a size standpoint, me hearties, but I be surprised t' find that it be considerably bigger than it's Estes counterpart.

T' Semroc version o' t' Astro-1 comes in t' traditional hangin' bag with t' parts clearly visible through t' bag back. Well, blow me down! T' instruction booklet doubles as a face card and inside t' instruction sheet, arrr, one finds a mini-history lesson on both t' rocket and t' company that originally produced it, somethin' I consider a nice touch. Ahoy! There's also a well detailed assembly guide and an exploded view o' t' rocket (in a "centerfold" that only a BAR could love.) T' parts are nicely done and include what has become a mod-roc staple o' late; laser cut fins and a Keelhaul®©™-based shock cord system. Begad! T' fin sheet be t' most impressive part o' t' unbuilt kit, arrr, almost an art piece unto itself with t' laser etched Semroc logo and kit name. T' balsa itself is fairly hard, shapes easily, me bucko, and needs little in t' way o' cleanup after removal from t' spar. Arrr! Begad! Overall t' feelin' o' quality permeates this kit and t' three other Semroc offerings that I've built. Begad! T' rocket is a legitimate skill level one project with t' most complicated step in t' instructions bein' t' installation o' t' motor mount and Keelhaul®©™ shock cord, shiver me timbers, me bucko, nay a step likely t' cause a panic attack even in a beginner. After this is completed t' project is a simple 3FNC build and it progresses quickly, but I did things a little backward for a change.

Finishing:
Followin' t' advice o' a fellow OldRockets poster, me hearties, I sprayed t' body tube with a coat o' Valspar primer before I attached t' fins or started t' sealin' or sandin' process. Theoretically this was supposed t' toughen t' body tube for t' sandin' process. Arrr! Turns out it works. Ya scallywag! Even at t' top o' t' body tube where I had become accustomed t' some frayin' t' tube held together well. Ya scallywag! Begad! T' primer was followed by t' requisite two coats o' thinned Elmer's Fill 'n' Finish with each coat followed by a brisk sandin' with very fine grit sandpaper. Aye aye! Well, matey, blow me down! Nay only did this hide any tube spirals, me hearties, it also roughened up t' body tube and gave t' fins a little more t' bite onto once they were glued in place. Avast! T' fins were attached usin' t' double glue method usin' Elmer's Wood Glue and were also finished as t' body tube was with Fill 'n' Finish. Arrr! After t' fins were sanded, t' entire rocket was re-sprayed with primer, then with a base coat o' ValSpar gloss white. Once dry, t' fins were masked and sprayed with ValSpar Cherry Red, me bucko, while t' nose cone was sprayed with ValSpar gloss black. Aye aye! Begad! After a light coat o' acrylic clear t' decals were applied. Ahoy! They went on with ease and nicely completed t' look. Avast, matey, me proud beauty! Once everythin' be dry I applied another coat o' clear and called t' project finished.

Flight:
T' first launch was a rarity, a Leap Day launch, me hearties, but that fact passed me by until that evenin' when I be enterin' t' flights into t' flight log. Ya scallywag! Like I said earlier, arrr, I expected t' Astro-1 t' be much like t' Estes Alpha in it's flight characteristics, shiver me timbers, ya bilge rat, but as it turned out, I liked it even better. For t' size o' t' field I was flyin' on, t' Astro-1 is tough t' beat. T' added size cuts down on t' height while makin' t' whole flight visible. Well, blow me down! Ya scallywag! Flyin' on a B6-4, me hearties, t' rocket flew t' a respectable height and managed t' recover on t' field despite t' full chute and constant breeze. Well, blow me down! Havin' proved it's small field worth, arrr, I looked forward t' a chance t' try it out with a C engine on a big field. A month later I finally got around t' launchin' it on t' big field at VOA with t' Cincinnati Quark group. Begad! Since I had a lot more room t' work with, arrr, I loaded up a C6-5 and let 'er rip despite t' relatively heavy breeze. Begad! Ya scallywag! T' Astro-1 arced into t' wind and flew t' a nice altitude with ejection comin' right before apogee (so a C6-7 might have been a better choice.) Again under a full chute, me hearties, me bucko, t' rocket began driftin' with t' wind t' t' northwest, me bucko, well away from our launch site. Well, blow me down! From where we stood it looked like it might land near t' park's edge, shiver me timbers, so I decided t' drive t' t' landin' site instead o' plowin' through t' thistles and swampy spots that lay betwixt me and t' rocket. Begad! I drove t' t' site and began walkin' along t' sight line, arrr, but found no rocket. Thirty minutes later I disappointedly decided that I had indeed been beaten, shiver me timbers, but on t' drive back I realized that t' row o' cars I had been usin' as a point o' reference were nay parked on t' Quark flight line, so I decided t' try again. Again nothing, ya bilge rat, so then I really gave it up. Aye aye! Ya scallywag! Apparently that be what did it. Blimey! Well, blow me down! I hadn't moved t' van 100 feet when I saw t' Astro-1 hangin' from a thistle a mere 25 feet from t' road, matey, but completely on t' opposite side o' t' access road. I guess t' drift only looked extreme from where I stood because I was a good 1/4 mile away from where I had been searching.

Flight Rating: 5 out o' 5

This is strange...that rocket looks almost exactly what Alpha's look like when the trailing edge is glued on instead of the root edge...wierd.
