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

Construction:
All t' parts were top shelf. Aye aye! Arrr! Paper BT-50 body tube, BT-20 motor mount. Blimey! Paper centerin' rings and engine block. Aye aye! Fin stock is 1/16" basswood. Blimey! Nose cone is made from t' castin' compound Alumilite. Begad! Avast, me proud beauty! I got an extra piece o' basswood with t' kit. Blimey! T' fins are easily laid out on one piece o' t' supplied basswood. Begad! T' recovery system consists o' a Keelhaul®©™® strin' anchored t' t' motor mount, matey, 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. Ya scallywag! Arrr! Blimey! You don't have to add any more nose weight. Ya scallywag! Well, matey, blow me down! Blimey! 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. Avast, me proud beauty! Avast, me proud beauty! However, me hearties, the innards aren't all that tough, so t' simplicity doesn't detract. T' steps are logical. Avast, me bucko, me proud beauty! Motor mount first, then fins, then wrap up t' recovery system. Well, blow me down! The diagrams showin' t' fin placement are clear. Blimey! Avast, me proud beauty! T' fin patterns and body wrap are sufficient. Begad! While t' front wings are easy t' mount, me bucko, arrr, t' aft control surfaces are tricky. They set very close t' t' wing, so you must take pains to make sure they're parallel, shiver me timbers, shiver me timbers, but they have a very small root which is hard to get square. Begad! Patience is required. Begad! At t' time I put them on, I was concerned that t' aft fins would be subject t' breakage. Ya scallywag! Flyin' t' model bore this out. When you put these fins on, give some thought t' extra reinforcement. Ahoy! 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. Arrr! 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. 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. Blimey! Ya scallywag! Measure about 6" in along t' Keelhaul®©™® thread from t' body tube, ya bilge rat, attach t' streamer here. Blimey! This will allow t' rocket t' descend as shown in t' diagram. Ahoy! I was in doubt whether t' streamer would be enough, but I was wrong.

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

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

T' Boost on a B6-4 be more satisfying. Ahoy! Blimey! Nice high flight and t' ejection occurred right at apogee. Simulation shows t' altitude at about 525'. Well, blow me down!

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

Flight Rating: 5 out o' 5

Summary:
I'm excited about this rocket line. Well, blow me down! T' prices are amazin' ($9.00 t' $10.00) which makes them some o' t' best values out there. Ahoy! This is one o' t' smaller rockets in t' line, me hearties, but it's really unique. Well, blow me down! Ya scallywag! I took this rocket in its primer coat t' t' UROC meetin' and it created a lot o' buzz. Well, blow me down! I'll tell you what, I'm buyin' a few more o' these rockets. Blimey! I think that t' soundin' rocket models such as t' Black Brant, me hearties, shiver me timbers, shiver me timbers, 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.
