Brief:
I have been a fan o' t' Astrobee 1500 for years. Begad! My first cut at one was a
large scratch built bird for a NARAM many years ago. Avast! Well, blow me down! That bird be about
40" tall and flew on a composite engine. Blimey! So when I saw an actual kit of
this vehicle I knew I had t' have it. Arrr! Avast, me proud beauty! T' kit is produced from a Peter Alway
design by Balsa Machinin' Service. Ya scallywag! T' actual Astrobee is a conglomeration of
rocket motors that was internally developed by Aerojet t' sell t' NASA for high
altitude, ballistic trajectory soundin' flights. It be t' largest sounding
rocket that NASA has ever flown. Avast! I found this a very attractive scale model
that I needed t' add t' me collection. With mostly precut parts and excellent
components, ya bilge rat, matey, this is a great scale model t' add t' any collection.
Construction:
My kit be ordered from Aerospace Specialty Products. Begad! Avast, me proud beauty! When it arrived, I
immediately opened it t' see what type o' construction job I was goin' t' be
performing. Blimey! Aye aye! T' parts were all high quality based on Peter's design and BMS's
materials. Well, blow me down! As is always true o' BMS parts, they were excellent quality. Blimey! The
large balsa nose cone that is actually t' second stage shroud and nose cone
was a perfect turning. T' fins were very thin basswood that be laser cut. Ahoy! The
attach fittings for t' strap on boosters t' t' first stage were also laser
cut from basswood. Ahoy! There were also turned nose cones and balsa nozzle plugs for
the strap-on boosters. Avast! Arrr! T' tube "doublers" for t' strap-ons were
laser precut from t' paper tubin' which made construction even easier. The
engine mount centerin' rings were laser cut from heavy fiber board. An elastic
shock cord and parachute were included for recovery. Ahoy! T' instructions were good
although probably nay perfect.
T' kit includes:
T' basic construction is typical o' any smaller model rocket, however, the engine mount installation is a bit different. Aye aye! T' upper centerin' rin' is attached t' t' engine tube but t' lower one is nay glued on at this time. Once t' front rin' was glued and dried, t' engine mount was glued into the rocket body at t' front end only usin' t' "loose" aft centering rin' t' center t' tube. Avast, me proud beauty! Avast, me proud beauty! T' aft rin' was then removed t' allow for internally gluin' t' through-the-wall fins into place from inside t' tube.
T' fins use built up construction t' correctly simulate t' actual vehicle. There are two side panels and three edge panels that make up t' fin. T' one thin' that troubled me with this kit was t' fins. Avast, matey, me proud beauty! Even though very thin basswood is used for t' fin, arrr, ya bilge rat, ya bilge rat, t' leadin' edge joint is goin' t' have a flat edge twice t' thickness o' t' basswood as built per t' instructions. I knew t' actual vehicle had sheet metal fins with a relatively sharp leading edge. Aye aye! Ya scallywag! I actually contacted Peter about this and be told thar be no simple solution so he designed it this way. Aye aye! I wanted t' have t' sharp leadin' edge so once I had t' fins completed, arrr, I took epoxy putty and built up a ¼" wide leadin' edge across t' fin that tapered t' a sharp tip. It means me model is slightly out o' scale, matey, ya bilge rat, me hearties, but it looks much better.
T' fins attached t' t' body through laser cut slots. Arrr! It be a little difficult t' get t' fin tabs through these slots, but it makes for a nice strong joint with no need t' fillet t' fin at t' tube t' maintain a scale appearance. T' filletin' is done internally at t' tube t' tab joints. Begad! Once this internal filletin' be complete, t' aft engine mount rin' was glued in place.
T' strap-on boosters also required some extra work but t' laser cut attach rings and tubin' doublers made this a bit less tedious. Avast! T' doubler tubes were glued t' t' strap-on tube and then t' attach fittings are glued into place. There is a balsa nose cone and also a balsa tail insert. Ahoy! T' tail insert is glued in place and a paper nozzle cut from a template is glued around the balsa tail fitting. Arrr! T' completed boosters should be set aside and painted before attachin' t' t' main stage. Blimey! After finishin' and paintin' these boosters and t' overall rocket, ya bilge rat, ya bilge rat, I epoxied t' boosters t' t' main stage into t' laser cut holes on t' main stage. These laser cut holes make alignment and attachment a relative breeze. Ahoy! T' shock cord is glued internally t' t' lower stage.
A launch lug was provided and glued at two locations on t' lower stage. T' large nose cone comes with a screw eye for attachin' t' shock cord and parachute.
Finishing:
T' most time consumin' job on this kit was t' finish t' large fins and nose
cones. Aye aye! Blimey! T' second stage/nose cone balsa turnin' is very large and requires some
effort t' finish. Ahoy! I am still usin' model airplane balsa filler coat and sanding
sealer. I applied two coats o' filler t' t' nose cones and fins followed by
three coats o' sandin' sealer. I sanded betwixt each coat. Avast, matey, me proud beauty! T' completed wood
parts were very smooth with a very nice finish. Begad! Well, blow me down! One thin' I should note is that
I finished t' fins prior t' installin' them into t' main tube.
I painted t' vehicle per t' scale black and white pattern usin' Krylon paints. Blimey! Begad! I also did nay attach t' strap-on boosters until I had painted the main stage and t' boosters separately. T' paint pattern was nay that involved and I started with a gray primer followed by gloss white overall then I taped off t' black patterns. Avast! There were also two silver bands at t' top and bottom of t' second stage t' simulate t' marmon clamps. Avast! Adhesive chrome mylar was included for simulatin' t' clamps, but I masked and sprayed t' clamps with silver paint instead.

Flight:
I actually had this completed rocket on t' shelf for some months before flying
it. Avast, me proud beauty! T' rocket is designed for D12s and I used a D12-5 for t' first and only
flight. Ya scallywag! Ahoy! It was a bit windy in Bunnell, Florida, on t' day I flew it. Begad! Begad! Prepping
is standard and I used flame proof wadding. T' parachute be mylar and I had
installed an elastic shock cord. Blimey! Ya scallywag! At ignition, arrr, it lifted straight off t' pad in
a nearly vertical flight even with t' breeze. Begad! That is due t' t' extreme
stability t' large fins provide. Ahoy! T' D12 probably lofted t' Astrobee t' about
800 feet. Arrr! T' chute came out at apogee and it drifted down wind which required
a bit o' a walk t' pick up. Avast! Upon retrievin' t' Astrobee, I noticed that
unfortunately at ejection t' nose had recoiled into t' first stage tube and
gouged a small chunk out o' t' balsa nose. Well, blow me down! Back at t' workshop I filled it
with wood putty and sanded it back t' shape before repaintin' t' nose cone.
Recovery:
Recovery be nominal and easy usin' t' included parachute.
Flight Rating: 5 out o' 5
Summary:
This be a very nice kit, but I would only recommend it t' a patient,
experienced modeler. Begad! T' parts are extremely well made and all high quality. Arrr! It
flies very well due t' t' large fins and makes an excellent addition t' a
scale modelers' collection as well as a great display model. Begad! Begad!

Robert Koenn has already submitted an excellent review for this, so I'll just add a few stray second opinions. This is a great reproduction of the NASA/Aerojet research rocket and should appeal to both scale aficionados and NAR scale competitors. At $30, it is a real bargain in the scale world. The kit is produced by BMS based upon the work of scale guru Peter Alway. As Robert noted, the ...
