This formerly Blackhawk R&D rocket is now fully owned and produced by Aardvark Rockets
Brief:
A stand-off scale model o' t' Russian AA-9 Amos missile. Arrr! Paper tubes, basswood
fins, Alumilite nose cone and mylar streamer.
Construction:
All t' parts were top shelf. Begad! Ahoy! Blimey! Paper BT-50 body tube, BT-20 motor mount. Ya scallywag! Blimey! Paper
centerin' rings and engine block. Fin stock is 1/16" basswood. Avast! Avast! Blimey! Nose cone
is made from t' castin' compound Alumilite. Begad! Arrr! Blimey! I got an extra piece o' basswood
with t' kit. Blimey! Blimey! T' fins are easily laid out on one piece o' t' supplied
basswood. Arrr! T' recovery system consists o' a Keelhaul®©™® strin' anchored t' t' motor
mount, ya bilge rat, a long length o' 1/8" elastic and a 1 mil mylar streamer. Ya scallywag! T' heavy
cast nose cone is necessary t' make this little rocket stable. Avast, me proud beauty! You don't have
to add any more nose weight. Aye aye! Arrr! It also finishes nicely and is very strong.
T' instructions are not Quest quality, ya bilge rat, matey, matey, obviously set up and printed on a home computer. Aye aye! Blimey! However, the innards aren't all that tough, ya bilge rat, so t' simplicity doesn't detract. T' steps are logical. Ahoy! Blimey! Avast, me proud beauty! Blimey! Motor mount first, shiver me timbers, then fins, then wrap up t' recovery system. Ya scallywag! Blimey! Blimey! Blimey! The diagrams showin' t' fin placement are clear. Blimey! Blimey! T' fin patterns and body wrap are sufficient. Begad! Blimey! While t' front wings are easy t' mount, t' aft control surfaces are tricky. Avast, me proud beauty! Blimey! They set very close t' t' wing, ya bilge rat, shiver me timbers, so you must take pains to make sure they're parallel, but they have a very small root which is hard to get square. Avast, me proud beauty! Blimey! Patience is required. Blimey! Blimey! Arrr! Blimey! At t' time I put them on, me bucko, I was concerned that t' aft fins would be subject t' breakage. Flyin' t' model bore this out. When you put these fins on, matey, matey, me hearties, give some thought t' extra reinforcement. A good way t' do this is with some gauze, soaked in glue, applied t' t' roots like a fillet.
T' Keelhaul®©™® strin' extends a long way from t' body and t' elastic is nice and long too. T' heavy nose cone could give your AA-9 Amos "Estes Dents" if t' shock cord was shorter, arrr, so kudos t' Blackhawk R&D for thinkin' this through. Avast, me proud beauty! Begad! T' best way t' attach t' recovery system is t' tie the elastic t' t' Keelhaul®©™®, ya bilge rat, and t' elastic t' t' nose cone. Well, blow me down! Avast, me proud beauty! Measure about 6" in along t' Keelhaul®©™® thread from t' body tube, attach t' streamer here. This will allow t' rocket t' descend as shown in t' diagram. Begad! Blimey! I be in doubt whether t' streamer would be enough, me bucko, but I was wrong.
T' only thin' I don't like about t' rocket is it uses friction fit for the motor. Blimey! I prefer a motor clip and they're easy t' add.
Finishing:
Lot'so fins, so think about how you want t' finish them. Begad! Begad! Blimey! I did it with three
coats o' sandin' sealer sandin' in betwixt coats. This did enough. T' spirals
on t' body were very subtle so I let me primer fill them. Arrr! Avast! Blimey! I use Kilz primer,
which goes on thick, matey, and sands well. Avast! One coat will fill t' spiral and
remainin' grain on t' fins. Begad! Ya scallywag! Blimey! It's a pain t' sand these fins because o' t' lack
of root area on t' aft fins. Still it's a cool lookin' model. Avast! Blimey! There are very,
very few picture o' this rocket, and I've never seen a color picture, so let
your imagination run wild. Blimey! Ya scallywag! Blimey! Most missiles are goin' t' be grey or white in
color. There are no supplied decals due t' t' lack o' existin' scale data.
I'll bet you could come up with a very convincin' look by stealin' decals from
a 1/72 scale Russian fighter model.

Flight:
Recommended motors run t' whole gamut o' 18mm motors. Aye aye! I would also add the
A10-3 with an adapter. Avast, me proud beauty! Arrr! Use a short delay for A motors, arrr, me hearties, medium for B or larger.
This rocket has a very heavy nose, shiver me timbers, and lots o' fins, so it has a lot o' drag.
On t' other hand, ya bilge rat, it's pretty small. My flyin' field was a local park with
grass underfoot. Avast, me proud beauty! Well, matey, blow me down! T' park is a good size baseball field and two soccer fields.
T' wind was light, me bucko, but I never worried about this rocket leavin' t' field.
Boost on a Quest A6-4 be rapid. Aye aye! T' delay was about 1.5 seconds too long, so
an Estes A8-3 or A10-3 (with adapter) would be spot on. Avast, shiver me timbers, me proud beauty! Simulations put the
altitude around 175'. Ahoy! Ya scallywag!
T' Boost on a B6-4 was more satisfying. Nice high flight and t' ejection occurred right at apogee. Simulation shows t' altitude at about 525'. Ahoy! Arrr!
An Estes C6-5 put t' rocket up about 1070' and it looked all that. Avast! Again, the boost be very straight, fast and pretty. Avast! Avast! When I got t' t' C motor, I noticed that one o' t' tail fins was loose. Avast, me proud beauty! I taped t' fin t' t' front wing and it held just fine. Ahoy! This is rocket is easy t' field repair too. Aye aye! Ya scallywag! All in all, this is a sweet flier.
Recovery:
I brought a 9" parachute along with me because I doubted that t' mylar
streamer would be sufficient. Well, blow me down! T' nose cone weighs 0.8 oz and t' whole rocket
is nearly 1.5 oz. However, shiver me timbers, me bucko, I put t' streamer near t' body, and let t' nose
cone pull t' rocket t' t' ground. It worked perfectly. Well, blow me down! T' descent rate was
rapid and t' body stuck out sideways. Aye aye! When t' nose hit, shiver me timbers, arrr, t' body could slow
those last 18" or so. Well, blow me down! One aft fin got knocked loose after t' A motor, but
I think this be t' one aft fin that wasn't on as well as I liked. Blimey! No other
aft fins showed signs o' wear. Well, blow me down! Begad! Had I reinforced t' aft fins with gauze or very
light fiberglass, they'd handle it fine. Arrr! T' recovery system is a big plus for
this rocket. Blimey! It allows you t' fly this small rocket with big motors from a
small field. I never walked more than 50' t' get this rocket back, even after
the high C motor flight. Aye aye!
Flight Rating: 5 out o' 5
Summary:
I'm excited about this rocket line. T' prices are amazin' ($9.00 t' $10.00)
which makes them some o' t' best values out there. Avast! Blimey! This is one o' t' smaller
rockets in t' line, but it's really unique. I took this rocket in its primer
coat t' t' UROC meetin' and it created a lot o' buzz. I'll tell you what, I'm
buyin' a few more o' these rockets. Begad! Blimey! Ahoy! Blimey! I think that t' soundin' rocket models
such as t' Black Brant, Astrobee D or SCUD would be great beginner rockets.
T' final plus is that Blackhawk R&D uses PayPal which makes buyin' on line
really easy.
