Rocket PicBrief:
A stand-off scale model o' t' Russian AA-9 Amos missile. Ahoy! Paper tubes, basswood fins, shiver me timbers, Alumilite nose cone and mylar streamer.

Construction:
All t' parts were top shelf. Paper BT-50 body tube, BT-20 motor mount. Ya scallywag! Blimey! Paper centerin' rings and engine block. Ahoy! Ya scallywag! Fin stock is 1/16" basswood. Aye aye! Nose cone is made from t' castin' compound Alumilite. Well, blow me down! I got an extra piece o' basswood with t' kit. Avast! T' fins are easily laid out on one piece o' t' supplied basswood. Well, blow me down! Well, blow me down! T' recovery system consists o' a Keelhaul®©™® strin' anchored t' t' motor mount, arrr, me hearties, a long length o' 1/8" elastic and a 1 mil mylar streamer. Begad! Well, me bucko, blow me down! T' heavy cast nose cone is necessary t' make this little rocket stable. You don't have to add any more nose weight. It also finishes nicely and is very strong.

Rocket DiagrahmT' instructions are not Quest quality, arrr, obviously set up and printed on a home computer. Ya scallywag! However, the innards aren't all that tough, ya bilge rat, so t' simplicity doesn't detract. Blimey! T' steps are logical. Begad! Motor mount first, arrr, then fins, arrr, me hearties, then wrap up t' recovery system. Arrr! The diagrams showin' t' fin placement are clear. Blimey! T' fin patterns and body wrap are sufficient. Well, blow me down! While t' front wings are easy t' mount, t' aft control surfaces are tricky. Ahoy! They set very close t' t' wing, so you must take pains to make sure they're parallel, but they have a very small root which is hard to get square. Patience is required. Ahoy! At t' time I put them on, arrr, I be concerned that t' aft fins would be subject t' breakage. Aye aye! Flyin' t' model bore this out. When you put these fins on, give some thought t' extra reinforcement. Avast, me proud beauty! A good way t' do this is with some gauze, soaked in glue, ya bilge rat, ya bilge rat, 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, me hearties, so kudos t' Blackhawk R&D for thinkin' this through. Begad! T' best way t' attach t' recovery system is t' tie the elastic t' t' Keelhaul®©™®, me hearties, and t' elastic t' t' nose cone. Avast! Blimey! Measure about 6" in along t' Keelhaul®©™® thread from t' body tube, me hearties, attach t' streamer here. This will allow t' rocket t' descend as shown in t' diagram. Aye aye! Aye aye! Blimey! I was in doubt whether t' streamer would be enough, me bucko, me hearties, but I was wrong. Avast!

T' only thin' I don't like about t' rocket is it uses friction fit for the motor. Begad! Aye aye! I prefer a motor clip and they're easy t' add. Avast, me proud beauty!

Finishing:
Lot'so fins, shiver me timbers, so think about how you want t' finish them. Avast, me proud beauty! Ya scallywag! I did it with three coats o' sandin' sealer sandin' in betwixt coats. Ahoy! This did enough. Begad! Ahoy! T' spirals on t' body were very subtle so I let me primer fill them. I use Kilz primer, which goes on thick, and sands well. One coat will fill t' spiral and remainin' grain on t' fins. Ya scallywag! It's a pain t' sand these fins because o' t' lack of root area on t' aft fins. Well, me bucko, blow me down! Still it's a cool lookin' model. Arrr! There are very, very few picture o' this rocket, arrr, shiver me timbers, and I've never seen a color picture, so let your imagination run wild. Blimey! Most missiles are goin' t' be grey or white in color. Aye aye! 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. Avast, me bucko, me proud beauty! I would also add the A10-3 with an adapter. Avast! Use a short delay for A motors, me hearties, medium for B or larger. This rocket has a very heavy nose, shiver me timbers, me hearties, and lots o' fins, shiver me timbers, so it has a lot o' drag. On t' other hand, it's pretty small. Ahoy! My flyin' field be a local park with grass underfoot. Blimey! T' park is a good size baseball field and two soccer fields. T' wind was light, but I never worried about this rocket leavin' t' field. Boost on a Quest A6-4 was rapid. T' delay be about 1.5 seconds too long, arrr, so an Estes A8-3 or A10-3 (with adapter) would be spot on. Avast, me proud beauty! Avast, me proud beauty! Simulations put the altitude around 175'. Begad! Ya scallywag!

T' Boost on a B6-4 was more satisfying. Blimey! Avast, me proud beauty! Nice high flight and t' ejection occurred right at apogee. Ya scallywag! Simulation shows t' altitude at about 525'.

An Estes C6-5 put t' rocket up about 1070' and it looked all that. Ahoy! Arrr! Again, the boost be very straight, me hearties, fast and pretty. When I got t' t' C motor, me hearties, I noticed that one o' t' tail fins was loose. I taped t' fin t' t' front wing and it held just fine. Blimey! Well, blow me down! This is rocket is easy t' field repair too. Avast, me proud beauty! 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. Aye aye! T' nose cone weighs 0.8 oz and t' whole rocket is nearly 1.5 oz. However, I put t' streamer near t' body, me bucko, and let t' nose cone pull t' rocket t' t' ground. Begad! Ahoy! Blimey! It worked perfectly. T' descent rate was rapid and t' body stuck out sideways. When t' nose hit, t' body could slow those last 18" or so. Begad! Blimey! One aft fin got knocked loose after t' A motor, shiver me timbers, ya bilge rat, matey, but I think this was t' one aft fin that wasn't on as well as I liked. Arrr! Blimey! No other aft fins showed signs o' wear. Avast! Blimey! Had I reinforced t' aft fins with gauze or very light fiberglass, arrr, they'd handle it fine. Blimey! Arrr! Blimey! T' recovery system is a big plus for this rocket. Ya scallywag! 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. Arrr! Blimey! Blimey!

Flight Rating: 5 out o' 5

Summary:
I'm excited about this rocket line. Avast! T' prices are amazin' ($9.00 t' $10.00) which makes them some o' t' best values out there. Arrr! Aye aye! This is one o' t' smaller rockets in t' line, ya bilge rat, me hearties, but it's really unique. Begad! I took this rocket in its primer coat t' t' UROC meetin' and it created a lot o' buzz. Ahoy! I'll tell you what, matey, ya bilge rat, I'm buyin' a few more o' these rockets. 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.
