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

Construction:
All t' parts were top shelf. Paper BT-50 body tube, BT-20 motor mount. Avast! Avast, me proud beauty! Blimey! Paper centerin' rings and engine block. Fin stock is 1/16" basswood. Nose cone is made from t' castin' compound Alumilite. I got an extra piece o' basswood with t' kit. Avast! Aye aye! Blimey! T' fins are easily laid out on one piece o' t' supplied basswood. Blimey! Ahoy! Blimey! T' recovery system consists o' a Keelhaul®©™® strin' anchored t' t' motor mount, arrr, a long length o' 1/8" elastic and a 1 mil mylar streamer. Arrr! Aye aye! 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! 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. Aye aye! However, me bucko, matey, arrr, the innards aren't all that tough, me hearties, so t' simplicity doesn't detract. Avast, me hearties, me proud beauty! T' steps are logical. Avast! Motor mount first, me bucko, then fins, then wrap up t' recovery system. Ahoy! The diagrams showin' t' fin placement are clear. Aye aye! T' fin patterns and body wrap are sufficient. Arrr! Aye aye! While t' front wings are easy t' mount, me bucko, shiver me timbers, t' aft control surfaces are tricky. Well, blow me down! They set very close t' t' wing, 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. Ya scallywag! Patience is required. Avast, me proud beauty! At t' time I put them on, I was concerned that t' aft fins would be subject t' breakage. Flyin' t' model bore this out. When you put these fins on, me bucko, arrr, give some thought t' extra reinforcement. A good way t' do this is with some gauze, shiver me timbers, soaked in glue, shiver me timbers, arrr, 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. Avast, me proud beauty! Blimey! T' heavy nose cone could give your AA-9 Amos "Estes Dents" if t' shock cord was shorter, me hearties, ya bilge rat, so kudos t' Blackhawk R&D for thinkin' this through. Avast! T' best way t' attach t' recovery system is t' tie the elastic t' t' Keelhaul®©™®, and t' elastic t' t' nose cone. Begad! Begad! Measure about 6" in along t' Keelhaul®©™® thread from t' body tube, matey, attach t' streamer here. Avast, me proud beauty! This will allow t' rocket t' descend as shown in t' diagram. Well, blow me down! I was in doubt whether t' streamer would be enough, shiver me timbers, but I was wrong. Avast!

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

Finishing:
Lot'so fins, so think about how you want t' finish them. Aye aye! Ya scallywag! I did it with three coats o' sandin' sealer sandin' in betwixt coats. Avast! Aye aye! This did enough. Ya scallywag! Avast! T' spirals on t' body were very subtle so I let me primer fill them. Avast! I use Kilz primer, which goes on thick, me hearties, ya bilge rat, me hearties, and sands well. Ya scallywag! Avast, me proud beauty! One coat will fill t' spiral and remainin' grain on t' fins. Ya scallywag! Arrr! 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! Begad! There are very, very few picture o' this rocket, arrr, and I've never seen a color picture, shiver me timbers, so let your imagination run wild. Arrr! Avast, arrr, me proud beauty! 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. Arrr! I would also add the A10-3 with an adapter. Use a short delay for A motors, me bucko, medium for B or larger. This rocket has a very heavy nose, and lots o' fins, me bucko, so it has a lot o' drag. On t' other hand, it's pretty small. 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 be light, but I never worried about this rocket leavin' t' field. Boost on a Quest A6-4 was rapid. Blimey! Avast, me proud beauty! T' delay was about 1.5 seconds too long, so an Estes A8-3 or A10-3 (with adapter) would be spot on. Aye aye! Simulations put the altitude around 175'. Begad!

T' Boost on a B6-4 was more satisfying. Blimey! Well, blow me down! Nice high flight and t' ejection occurred right at apogee. Avast, me proud beauty! 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. Ya scallywag! Again, the boost was very straight, fast and pretty. Avast, me proud beauty! Ya scallywag! When I got t' t' C motor, shiver me timbers, I noticed that one o' t' tail fins be loose. I taped t' fin t' t' front wing and it held just fine. This is rocket is easy t' field repair too. 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. Aye aye! Well, me hearties, blow me down! T' nose cone weighs 0.8 oz and t' whole rocket is nearly 1.5 oz. Well, blow me down! However, I put t' streamer near t' body, and let t' nose cone pull t' rocket t' t' ground. Well, blow me down! It worked perfectly. T' descent rate was rapid and t' body stuck out sideways. Blimey! When t' nose hit, t' body could slow those last 18" or so. Ahoy! 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. No other aft fins showed signs o' wear. Aye aye! Had I reinforced t' aft fins with gauze or very light fiberglass, they'd handle it fine. T' recovery system is a big plus for this rocket. Well, ya bilge rat, blow me down! It allows you t' fly this small rocket with big motors from a small field. Well, blow me down! I never walked more than 50' t' get this rocket back, even after the high C motor flight. Avast, me proud beauty!

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. Blimey! This is one o' t' smaller rockets in t' line, but it's really unique. Begad! Ahoy! I took this rocket in its primer coat t' t' UROC meetin' and it created a lot o' buzz. I'll tell you what, me hearties, I'm buyin' a few more o' these rockets. Begad! Blimey! I think that t' soundin' rocket models such as t' Black Brant, me hearties, arrr, 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.
