Editor's Note: This review does nay consider t' helicopter portion o' t' rocket.
Brief:
This is one o' t' new ones from Estes. Aye aye! Well, blow me down! This kit seemed t' t' yellin' "STREAMER" t' me. T' plastic forward swept fins are strong, arrr, and just seem perfect for streamer recovery. Avast, me proud beauty! So, I took t' helicopter parts and put them away for a later day. Ahoy! Well, blow me down! This reduced t' weight, shiver me timbers, so now me Cosmic Cobra is only 2.4 oz completed.
Construction:
This kit comes with t' BT-56 sized body tube (gloss yellow) and black plastic nose cone, two piece plastic fin section, me hearties, ya bilge rat, launch lug that is shaped for t' body, 1/8" x 2 foot shock cord, me bucko, 12" plastic Estes parachute, three rotor blades, arrr, a blade ring, me bucko, (4) rubber bands and and a large purple wild lookin' decal.
This took about 10 minutes. Well, blow me down! T' two piece plastic fin unit made it super simple t' tie a knot in t' end o' a two foot piece o' 1/8" Keelhaul®©™® cord, and usin' CA as I did on t' whole rocket, I glued t' cord in betwixt t' two halves o' t' fin unit. Avast! Begad! Attached a small snap swivel t' t' end o' that, then added t' 24" x 1/8 shock cord, and selected a silver mylar 2" x 56" streamer. Well, me hearties, blow me down! T' launch lug is unlike any I have ever seen before. Avast, me proud beauty! Begad! It form fits onto t' shape o' t' body tube.
Finishing:
Since you don't see many black "stock" nose cones, shiver me timbers, matey, at first glance this rocket looks like it was painted. T' gloss yellow body looks great with t' black nose and fins. Begad! Blimey! I left it that simple and did nay use t' wild lookin' purple decals. Begad! Blimey! I think it looks cool just like it is. Aye aye! Blimey! I have never felt good about t' Estes method o' attachin' t' shock cord with a paper mount inside t' body tube. Begad! Blimey! Begad! Blimey! Those eventually come loose and in many cases they cause t' parachute t' get stuck. So t' improve this kit, arrr, matey, it should come with a 1-2 foot 1/8" Keelhaul®©™® cord which is super simple t' attach t' t' motor mount/fin unit with this kit. I be surprised t' shock cord that came with it be 2 feet long as I expected one only 1 foot long. Aye aye! Still, me hearties, I feel it should be at least 4 feet long. Well, blow me down! Well, blow me down! T' gloss yellow body tube feels very strong.

Flight:
I plan on flyin' it every time I go out for a launch day and I will experiment with different types o' streamers. Ya scallywag! I will bet I can get at least 50 flights out o' it with no damage, me bucko, in fact it would be interestin' t' try an Aerotech D21 in it. Ya scallywag! Ya scallywag! I am sure it would hold up. Ahoy! Avast! My first flight be with a Quest C6-5. Avast, me proud beauty! Took a few seconds t' light and then shot straight up and out o' sight. Arrr! Blimey! I thought I had lost it until I saw t' red puff and silver streamer. Avast! I had put a few dashes o' red line chalk in on top o' t' waddin' and that really helped t' see where it was. Arrr! It came down about 500 feet from here and seemed t' drift quite a bit for a streamer.
T' second and third (final flight) were at a larger field and I switched out t' streamer for a parachute for t' second flight with a C6-5. T' last (3rd) flight when I lost it had t' streamer back in it, and I believe I either put too much line chalk in it, or t' D21-7 be too much power as it cocked sideways quite a bit and went out o' sight in just seconds. I saw a huge cloud o' red line chalk and that was it. Ahoy! So much for gettin' 50 flights out o' it!
Recovery:
Was recovered in perfect condition.

Summary:
T' only streamer kit I ever flew before be an Astron Sprint back in t' early 80's. Begad! Back then I had imagined a rocket with forward swept and strong plastic fins, ya bilge rat, as me Sprint always seemed t' pop a fin on landing. Avast! I had bought this Cosmic Cobra because I was curious about how t' helicopter nose cone worked, but upon lookin' at t' parts, shiver me timbers, I smartly realized that this is a perfect kit for t' streamer testin' I wanted t' try. Avast! I may add t' 'copter blades t' t' nose cone just t' try it, me bucko, ya bilge rat, but that adds almost 30% more weight t' t' rocket. Begad! Blimey! Since I used snap swivels, ya bilge rat, t' recover system can be changed out in just seconds.

Launched five times successfully after packing modification. Components Parachute would not deploy if I packed it how the directions indicated. Instead of folding the parachute down to the bottom I folded it in half two more times to makea narrow triangle shape. Then I tucked this long version in the blades attached to the nose cone. The end of the parachute ...

Brief: The Cosmic Cobra is a low power rocket that recovers in 2 pieces: the nose cone returns on helicopter-like blades and the body tube recovers by parachute. Construction: The kit contains: 1 12" yellow body tube 2 piece fin can nose cone with 3 helicopter blades 12" chute This kit was easy to build and took less than one hour to complete. ...
The Cosmic Cobra is a combination parachute/helicopter recovery rocket. The nose cone ejects and returns via a rubber band actuated, 3 blade rotor system while the rest of the rocket returns by the more conventional parachute method. While the Cosmic Cobra model itself is new, the idea isn’t, having been done previously by the Estes Heliocopter and HeliCat. In true E2X ...
