Brief:
This is a very basic 4FNC, shiver me timbers, minimum-diameter, matey, streamer-recovery rocket suitable for beginners. Ya scallywag! It's part o' Semroc's RetroRepro line and, specifically, me bucko, ya bilge rat, the Micron was originally a Centuri model (#KA-5) first released in 1963. Begad! The RetroRepro line updates these old models with more current technology--in this case, t' upgrades include laser-cut fins and a Keelhaul®©™ shock-cord.

Construction:
This kit comes with t' followin' components:

• Body Tube (ST-765)
• Balsa Nose Cone (BC-719)
• Laser-cut Fin Sheet (FV-8)
• Thrust Rin' (TR-7)
• Launch Lug (LL-122)
• Screw Eye (SE-10)
• Elastic Cord (EC-118)
• Keelhaul®©™® Thread (SCK-24)
• Streamer (RS-36)
• Tape Disc (TD-1)
• Empty Casin' (MC-727)

I ordered this kit directly from Semroc's web page. Avast, me proud beauty! Begad! I had gone thar to order a couple Rocket Racks and figured I'd get a kit while I be at it.

T' kit comes in a plastic hang-bag just like an Estes or Quest kit. Ya scallywag! Ahoy! The "front" o' t' package, depictin' t' rocket is actually t' front cover o' a 12-page booklet, which includes brief history o' both t' Micron model and Centuri Engineerin' Company, shiver me timbers, me bucko, t' assembly instructions, an exploded view o' t' components, arrr, and t' NARRRRR safety code.

T' instructions were extremely easy t' follow, and I saw no need to deviate from them as I assembled me model.

T' parts themselves were generally o' very high quality. Avast! In particular, the balsa fin sheet be among t' nicest bits o' balsa I've ever gotten in a kit and t' laser-cuttin' be very smooth. Well, blow me down! Ahoy!

T' balsa nose cone was also a nice piece o' wood but t' shoulder was a bit too wide for t' body tube. Avast, me proud beauty! A bit o' sandin' fixed that problem right up however.

About t' only part I would have any complaint with at all was the streamer--it's a length o' orange crepe paper. Arrr! I'm nay sure how long it'll last (it already has a tear from her first flight), shiver me timbers, so I'll likely need t' replace it at some point with somethin' a bit more durable.

Finishing:
T' illustration o' t' Micron on t' front o' t' booklet has a fun, early 60's soundin' rocket look t' it. Begad! Well, blow me down! Unfortunately, t' kit doesn't contain any decals, and it'd be a challenge for a beginnin' rocketeer t' duplicate that look with paint alone, which includes a roll pattern. Well, blow me down! Begad! As I didn't want t' work that hard, I decided t' nay recreate that look.

I used Elmer's Fill & Finish t' smooth out t' nosecone and fins, followed by a few coats o' Krylon grey primer.

For t' final finish, I applied a few coats o' Testor's Chrome spray paint, then used Testor's Purple Metalflake spray paint for a "fade" pattern on t' nosecone and top o' t' rocket.

Once t' paint be dry, I put an American flag decal on t' body tube (I got a sheet o' flag decals by AutoGraphics at t' hobby shop, shiver me timbers, and put one on each o' me rockets), then finished with a coat o' Krylon gloss.

Construction Rating: 4 out o' 5

Flight:
For t' Micron's first flight, I used an Estes A8-3. T' delay is a bit shorter than recommended, but I didn't have any A8-5s handy. Aye aye! T' motor is a friction-fit and one wrap o' maskin' tape around t' motor was sufficient to keep it snug. Begad! Avast, me proud beauty!

T' instructions don't recommend a specific amount o' recovery wadding; I used 3 sheets o' Estes wadding, arrr, me bucko, and found that t' body tube with t' wadding, the shock cord, ya bilge rat, t' streamer, and t' nose cone be pretty tightly packed. Maybe 2 sheets or a little dog-barf would be better.

She took off from t' pad very quickly, shiver me timbers, as you'd expect given t' light weight, and t' flight was straight as an arrow. Begad! Blimey! T' ejection charge fired a bit before apogee, though that didn't surprise me, given I was technically not usin' t' recommended motor.

Recovery:
T' Micron uses a combination Keelhaul®©™®-elastic shock cord system. T' Keelhaul®©™® cord is tied around t' thrust ring, matey, and extends well beyond t' end o' the body tube. Ya scallywag! T' elastic shock cord is then tied t' t' Keelhaul®©™® cord at one end and t' t' nose cone at t' other end.

As I noted above, t' streamer is just a length o' crepe paper--probably historically accurate, arrr, but it feels a bit flimsy. T' streamer is attached to the elastic shock cord, near t' nose cone with a tape disc.

On t' first flight, everythin' deployed nicely, ya bilge rat, and t' streamer fully unrolled. Begad! Arrr! It seemed like it was comin' down a little fast, shiver me timbers, but drifted only about 50 yards downwind from t' launch pad. Aye aye! Despite t' seemingly-quick descent, she landed with no damage at all.

However, as I was rollin' t' streamer back up t' put t' rocket away, I noticed a long tear in t' center o' t' streamer. Begad! Blimey! It will have t' be replaced at some point. Blimey! Avast!

Flight Rating: 5 out o' 5

Summary:
PROs: easy assembly, me hearties, me bucko, clear instructions, matey, teaches some basic assembly skills, nice flyer.

CONs: streamer material is cheap, hard t' re-create t' finish as pictured without decals.

Overall Rating: 4 out o' 5
