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:
This kit was easy to build and took less than one hour to complete.
Finishing:
No finishing was required. The kit comes with a cool decal.
Construction Rating: 5 out of 5
Flight:
First flight was on a B6-2. Great flight but even with 5 sheets wadding, it was
too much for the parachute.
Second flight was on a C6-3 and 6 pieces of wadding. Higher fligth but same result with the parachute.
Third flight was on a B6-4, which is too long of a delay, causing the rocket to eject from only 70ft up. However, with 8 sheets wadding it recovered safely.
I like that it has good, stable flights but don't use B6-4 or C6-5 motors.
Recovery:
PROs: the helicopter nose is cool and is more than likely to work well.
CONs: it needs 8 sheets wadding to keep from burning the parachute.M/P>
Flight Rating: 4 out of 5
Summary:
The Cosmic Cobra is a cool first or second rocket. For less than $12, it's a
great deal. Get this rocket!

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: This is an E2X kit single stage with parachute for the body and helicopter recovery for the nosecone. Construction: The kit consists of a pre-molded fin/MMT unit, 12" plastic parachute, single BT-60 tube, and plastic nose cone. This is an easy kit to assemble. Instructions are straightforward and easy to follow. Assembly can take between 30 minutes or so, depending on ...
Editor's Note: This review does not consider the helicopter portion of the rocket. This is one of the new ones from Estes. This kit seemed to to yelling "STREAMER" to me. The plastic forward swept fins are strong, and just seem perfect for streamer recovery. So, I took the helicopter parts and put them away for a later day. This reduced the weight, so now my Cosmic Cobra is only 2.4 oz ...
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 ...
Very first flight lifted off slowly after a longer than usual ignition delay. Nose cone separated at apogee, all fins deployed for a nice autogyro descent. Rocket body was not so fortunate. Parachute shroud lines were severed by the ejection blast (due to lack of wadding on my part). Rocket survived with just a small dimple in the tube. Parachute was never found. I plan to replace the lost chute with a streamer or small chute and use more wadding next time. I think the provided decal makes the rocket look gaudy. I would suggest leaving it off . My rotor blades were purple, which helped visibility during descent. I like this rocket, no curse here (except for that hidious decal).
