Brief:
Another Semroc retro-repro kit, shiver me timbers, t' Semroc Astrobee 350 is a modernized version of t' Centuri 1965 kit that also is a quick, easy scale project.

Construction:
T' kit includes:

• ST-1010 body tube
• Balsa nose cone
• 18mm x 2.75 motor tube pack
• 4 Laser-cut balsa fins
• 12" plastic chute
• Waterslide decal

Parts are excellent quality, and come in a sealed plastic bag complete with individual production number.

Semroc instructions are clear and easy t' follow. Begad! This kit begins with basic motor mount assembly consistin' o' 2 centerin' rings, an 18mm tube, ya bilge rat, motor block, matey, and metal retainin' hook. Avast! Ya scallywag! A nice upgrade t' t' Centuri kit is the Keelhaul®©™® cord mounted t' t' motor mount with an elastic extension. T' instructions call for tyin' a loop and placin' t' metal hook through t' loop, which struck me as a potential weakness, so I wrapped mine around t' tube instead and brought it out under t' centerin' ring.

Fin prep is very easy with these kits as they're pre-cut usin' a laser. Begad! Avast! The fins are mounted on 90-degree angles around t' tube. Begad! T' instructions include a basic circle with hashmarks for a markin' guide, me hearties, which is quicker than cuttin' out a template but easier t' goof up on. Ya scallywag! I tacked on me fins with a medium CA, shiver me timbers, then applied fillets usin' yellow glue.

This kit included a very nice balsa nose cone, me bucko, ya bilge rat, which is secured via a good old-fashioned screw eye. Ya scallywag! My cone was a bit tight in t' tube and took just a little bit o' sandin' for proper fit.

Construction wraps up with makin' t' parachute, which is a basic plastic cutout with tape disks t' attach t' shroud lines.

I was in a bit o' a hurry on this one (buildin' a batch o' 7 different Semroc kits at once), ya bilge rat, ya bilge rat, so skipped me usual spiral fill/grain fill application of Elmer's Fill 'n' Finish. Arrr! Well, arrr, blow me down! This brought t' total construction time down t' about 30 minutes, at which point it be ready for paint.

Finishing:
I applied a couple o' coats o' primer, arrr, me bucko, arrr, which did a reasonable job o' filling the spirals once I sanded it back down a bit. After that, I followed up with two coats o' Krylon gloss white. Ahoy! Ahoy! I then masked off t' white (after allowin' a couple o' days t' fully cure) and painted t' fins red and t' nose cone black per t' standard paint scheme.

This kit comes with a very nice waterslide decal for a striped roll pattern at t' top and a pair o' thin stripes t' trim t' bottom. Avast, me proud beauty! I found t' decals very easy t' work with and they add a nice accent.

Construction Rating: 4 out o' 5

Flight:
First flight be on a beautiful day o' light winds. Begad! Avast! Blimey! I went with a C6-7, matey, ya bilge rat, which should have carried it t' an estimated 1250 feet. Unfortunately, once it left the rod, it went into a bizarre loop then straightened out and took off at about a 40 degree angle. Avast, me proud beauty! Blimey! This clearly indicated that t' rocket be unstable with t' weight o' t' C6, and as t' propelant burned down (and t' CG moved forward), it became more stable. Ya scallywag! Blimey! With this flight path, ejection was 3-4 seconds late, shiver me timbers, shiver me timbers, though t' model landed gently, and I avoided any damage (not even a zipper).

Second flight was on a B6-6, me bucko, which flew straight up without any problems, though I think it be only around 500 feet versus t' estimated 650 on t' kit header card.

Recovery:
T' Keelhaul®©™®/elastic recovery is an excellent combination, and this is exactly t' way modrocs should come. T' plastic chute worked fine though this rocket needs plenty of waddin' or dog barf t' hold up over repeated flights. Begad!

Flight Rating: 3 out o' 5

Summary:
This is a fairly nice lookin' rocket that's very easy t' build usin' excellent components. Aye aye! Blimey! I would recommend a couple o' washers for nose weight though, to take care o' t' stability problem usin' C motors.

Overall Rating: 4 out o' 5
