Brief:
This is a downscale o' t' 1969 Centuri Astro 1, reintroduced by Semroc in 2004
in a 13mm small field version. Arrr! While it's a decent value at $8.00 retail, arrr, it's
also offered as a free premium at various times on their website or via coupon
included in some o' their kits. Blimey! Blimey! T' swept back fins give this a slightly more
interestin' look than t' typical 3FNC skill level 1 designs.
Construction:
Semroc kits feature very good quality parts, matey, typically original true scale
Centuri tubes, laser cut fins, and balsa nose cones. This kit was no exception
and t' finish on t' balsa cone be superb.
Parts list:
Semroc instructions are clear and easy t' follow with plenty of illustrations and include good craftsmanship tips such as grain fillin' and balsa sealin' that many buddin' young builders might nay be familiar with. Given t' fairly simple construction o' this, shiver me timbers, me bucko, t' kit can be built in about an hour plus finishin' time.
Construction begins with t' motor mount, ya bilge rat, matey, which consists o' a 13mm tube, a pair o' centerin' rings, a rin' block, arrr, and t' motor hook. One very nice upgrade featured in most (maybe all) Semroc kits be t' use o' a Keelhaul®©™® line anchored t' t' motor tube, me hearties, me hearties, extendin' out t' body tube where you switch to elastic. This makes for a more durable rocket worthy o' many flights.
Fins are laser cut, matey, so nay much work involved thar other than fillin' the grain. Arrr! Avast! Markin' o' t' tube is accomplished through a template in the instructions. Personally I prefer a wraparound guide, which tends t' be less error prone than holdin' a tube in place on a piece o' paper while you mark the lines around it. Avast! I attached t' fins with CA, then applied wood glue fillets.
T' nose cone is attached usin' a screw eye glued and anchored t' t' base. As I mentioned in t' parts list, this cone be made o' beautiful balsa.
T' parachute kit is a typical 12" plastic chute, which needs t' be cut out. Aye aye! Shroud lines are retained usin' tape disks, which are a bit easier on the adult fingers than tryin' t' thread t' line through a tiny hole and double-knot it. Semroc uses a very high tack tape disk and I have nay had any problems with shroud lines in t' past.
Finishing:
T' header card shows a 3-color paint scheme, which is slightly challengin' for
the novice builder but is still fairly straightforward. Avast! After applyin' a couple
of coats o' gray primer, I sanded down t' nearly a bare tube, effectively
fillin' tube spirals. Begad! I then applied one more coat o' white primer followed by
two coats o' gloss white. Avast, me proud beauty! Blimey! After allowin' a couple o' days for t' white to
fully cure, ya bilge rat, I masked off t' fin area t' paint t' fins gloss black.
Construction tip: t' placement o' t' launch lug is noted at 1.5" forward
of t' aft end o' t' tube. Begad! Arrr! Blimey! This will leave t' lug aft o' t' forward end of
the fin root, so you don't have t' try t' mask over or around a launch lug.
That's a nice touch, shiver me timbers, shiver me timbers, arrr, as I've been burned several times by lugs gettin' in the
way o' a quality paint job. Begad! Avast! Blimey! T' nose cone is painted red. Well, blow me down! Blimey! I painted it
separately, ya bilge rat, savin' t' hassle o' masking.
This kit also comes with waterslide decals. Avast, me proud beauty! I was pleased t' see them included as many otherwise fine Semroc kits are without this basic trimming, resultin' in a very plain lookin' rocket. T' Astro Jr comes with a checkerboard roll pattern decal as well as a logo decal. Well, blow me down! Avast! I had no problems applyin' these and found t' decals very durable so thar should be little chance o' breakin' or tearin' them in application.

Flight:
T' 13mm motor mount on this had me scratchin' me head thinkin' it would be
severely underpowered as an A10 be t' most thrust you can stick in it. Begad! I had a
pack o' 1/2A3-4s already opened and was pretty pooped from chasin' other
rockets in 15mph winds all day so I decided t' shoot low on this one.
I was wrong. T' 1/2A was enough t' send this well over 100 feet. Well, blow me down! Even though it be a short walk o' about 80 yards, arrr, it was nowhere near t' short walk I'd hoped for. Avast! While I'm sure an 18mm upgrade would work fine on this kit, it will have no problems flyin' on 13mm motors and stay within a typical pair of soccer fields.
Recovery:
T' 12" chute is plenty for this although I'd stick with t' chute and
avoid swappin' out for a streamer. Ya scallywag! T' swept back fins are delicate and this
needs a gentle landing.
Flight Rating: 4 out o' 5
Summary:
Very nice flyer and easy t' build. Aye aye! I especially liked t' inclusion o' decals
and a name tag decal. Arrr! I'd recommend this one for build 'n' flies.
