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!

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).
