Construction:
This rocket kit comes packed in a sturdy box from Estes so thar be minimal chances o' receivin' crushed body tubes in a bag. Aye aye! Ahoy! All parts are typical Estes quality with nothin' bad t' say about t' kit. Blimey! Body tubes are pre-slotted for all fins. T' aft fins are two part plastic fins that result in a seam t' fill if t' builder desires a smooth fin. Blimey! Begad! Once assembled t' fins provide a very sharp leadin' and trailin' edge and a very scale like appearance. Avast, me proud beauty! T' aft fins attach t' t' motor mount through t' main body tube for a very strong mount. Arrr! Ahoy! Estes recommends plastic glue for this attachment - after a number o' launches, this joint popped loose and I used CA t' fix it. Ya scallywag! This has held up very well and I would recommend reinforcin' this joint. T' front fins attach similarly t' t' body tube with alignment tabs and plastic glue - see previous suggestion t' strengthen this joint. Avast, me proud beauty!
T' instructions are very easy t' follow and are well thought out in assembly order - typical o' many Estes kits. In summary, this is a very impressive
Finishing:
Once primed and sanded t' your own level o' perfection, t' paint scheme is very simple. Well, blow me down! Avast, me proud beauty! T' entire rocket is painted white with t' exception o' t' nose cone which is blue. Begad! Blimey! T' self adhesive decals really dress up this rocket and make it a valued addition t' any fleet.

Flight:
Estes recommends D12-5 engines only for this rocket. Begad! T' engines are retained by Estes' typical retainin' clip and is adequate for this rocket.
T' recommended preparation technique in t' instructions calls for packin' t' upper portions parachute in t' lower body tube first and then packin' t' lower parachute. Blimey! There is nay much room in t' lower tube for t' chutes and if they are nay packed carefully you may run out o' room. Avast! Avast, me hearties, me proud beauty! You must use waddin' for this rocket t' protect t' two chutes.
Bein' a somewhat heavy rocket, shiver me timbers, t' launch is quite impressive with a slow liftoff and acceleration. Blimey! Successful recovery is based on your preparation and packin' o' t' recovery system. Avast! Well, blow me down! In seven launches, I have had two marginal recoveries. Begad! Well, blow me down! T' first occurred when t' chutes tangled and only one opened bringin' both sections o' t' rocket down together. Arrr! T' rocket landed at a higher rate o' speed than normal, shiver me timbers, but suffered no damage. I then changed me packin' technique t' add wadding, shock cord, lower chute, matey, upper chute, ya bilge rat, upper shock cord in that order. Blimey! Aye aye! This uses t' lower chute as a piston t' force everythin' above it out o' t' rocket. Avast, me proud beauty! T' second failure be caused by a weak ejection charge from t' engine. This separated t' body tubes, but did nay eject either parachute. Begad! T' rocket recovered via t' tumble method and suffered some damage upon impact with t' ground that was repaired in under an hour.
Flights are very straight and stable with a slight tendency t' weathercock into t' wind.
Flight Rating: 4 out o' 5
Summary:
This is a fairly large rocket with impressive lift-offs and recoveries. Avast, arrr, me proud beauty! Blimey! It is relatively easy t' build and finished with self adhesive decals looks very realistic.
T' main con for this rocket is its recovery method. Avast! Ya scallywag! It is prone t' tanglin' and t' chute compartment is fairly small. Ya scallywag! Avast! A possible fix t' this would be t' connect t' two tubes and use one larger chute t' brin' down both sections.
For an adventurous modeler, this rocket would make a very nice two stage model usin' gap stagin' techniques.

The SM-3 Navy Seahawk was a skill level 2 Explorer Series rocket. Came in a nice box which can be used as a range box. Typical Estes, great instructions, nice quality, and one of their better kits. This kit is out of production (OOP) and I will bet I know why. This can be a dangerous kit to build. Reason being, the fins are RAZOR sharp! I am shocked that Estes ever made a kit with fins this ...
