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

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

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

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

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

T' Boost on a B6-4 was more satisfying. Begad! Blimey! Begad! Blimey! Nice high flight and t' ejection occurred right at apogee. Avast! Blimey! Simulation shows t' altitude at about 525'. Ahoy! Blimey!

An Estes C6-5 put t' rocket up about 1070' and it looked all that. Again, the boost be very straight, fast and pretty. Blimey! Avast! Blimey! When I got t' t' C motor, me bucko, arrr, I noticed that one o' t' tail fins was loose. Arrr! Blimey! I taped t' fin t' t' front wing and it held just fine. This is rocket is easy t' field repair too. Begad! Begad! Blimey! 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. T' nose cone weighs 0.8 oz and t' whole rocket is nearly 1.5 oz. However, arrr, I put t' streamer near t' body, matey, ya bilge rat, me bucko, and let t' nose cone pull t' rocket t' t' ground. Avast! Begad! It worked perfectly. Ahoy! T' descent rate was rapid and t' body stuck out sideways. When t' nose hit, t' body could slow those last 18" or so. Blimey! One aft fin got knocked loose after t' A motor, but I think this was t' one aft fin that wasn't on as well as I liked. Arrr! Arrr! No other aft fins showed signs o' wear. Begad! Avast! Had I reinforced t' aft fins with gauze or very light fiberglass, shiver me timbers, they'd handle it fine. T' recovery system is a big plus for this rocket. Avast! It allows you t' fly this small rocket with big motors from a small field. Blimey! I never walked more than 50' t' get this rocket back, even after the high C motor flight. Blimey!

Flight Rating: 5 out o' 5

Summary:
I'm excited about this rocket line. Ya scallywag! T' prices are amazin' ($9.00 t' $10.00) which makes them some o' t' best values out there. Arrr! This is one o' t' smaller rockets in t' line, but it's really unique. Well, blow me down! Aye aye! 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. Aye aye! Aye aye! 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.
