Rocket PicBrief:
The HyperX is an "Ready to Fly" (RTF) that has a nose cone that comes down as a helicopter. The body tube uses a 'chute for recovery.

Construction:
The HyperX, on the outside, is a basic 4FNC rocket. Pulling the nose cone out reveals three blades attached to the nose cone. Each blade is about 4 inches long. The motor mount uses a retainer ring instead of the usual Estes motor retainer clip. Due to the length of the blades, the shock cord is mounted WAY down the body tube.

Since this is an RTF, there is very little construction. Even the chute was preassembled and attached to the shock cord. The only assembly required was to attach rubber bands to the nose cone blades. The rubber bands provide the tension necessary to unfurl the blades after the nose cone has been ejected from the body tube. The fin unit/motor mount is molded plastic. While it is no fun for modeling purposes, the plastic is very durable and can withstand hard impacts. The same applies to the plastic nose cone. The "launch lug" is a molded piece of plastic, with two rings to guide the launch rod. One major drawback to the construction is the very slender shock cord mount (probably 1/8"). Like I said, the shock cord is mounted very deep into the body tube to give the nose cone fins some room. This places it closer to the engine's ejection gases. No doubt this shock cord is going to be burned off soon. Remounting the shock cord at the same depth might be tricky.

Finishing:
No finishing necessary.

Construction Rating: 3 out of 5

Flight:
Recommended motors are the B4-2, B6-2/4, and the C6-3. I used the fins on the nose cone to pack the recovery wadding as far as possible into the body tube. The parachute and shock cord were then put into the tube. The nose cone blades were collapsed, and the nose cone slid easily into place. The motor retainer ring twisted off easily, the motor was inserted, and the retainer ring twisted securely on. The first flight was on a B6-2. Shortly after leaving the launch pad, the rocket took off on a 45 degree angle. It probably didn't get more than 100' off of the ground. The ejection charge kicked in, and the nose separated. The nose dropped like a rock for about 15 feet before the blades kicked in. The nose cone's descent rate was pretty slow, and on a windy day it will definitely drift quite a bit. The body tube came down rather quickly on a 12" chute. The second and third flights were better, also on B6-2s, but not straight up. The HyperX flies each time like it is weathercocking, except that it does not necessary point into the wind. Each time the nose cone drifted a lot. This is definitely not a rocket to fly on a windy day. It's also a fairly heavy rocket, so the flights are not that high. Launch it on a C if you have the room to recover the nose cone unit. Still, the helicopter recovery makes this a fun rocket to fly. It is one of my son's favorite rockets to watch.

Recovery:
Like I said, the nose does drift quite a bit. But after several flights, the only noticeable wear is the typical scorch marks on the shock cord.

Flight Rating: 3 ½ out of 5

Summary:
The HyperX is not a great flying rocket, but it is a lot of fun, especially for kids. It seems to be a very sturdy rocket. The only things that might wear out are the shock cord, and the rubber bands on the nose cone. The biggest con is that is is an RTF! This would have made a great kit.

Overall Rating: 3 ½ out of 5

GUEST's OPINION:
12/03 - "This is the past of the Cosmic Cobra E2X. Estes just changed the decal and made it an E2X." (J.R.)

GUEST's OPINION:
02/02 - "I think the Estes Hyper X is good. How ever I haven’t launched it a lot yet but this is what I did. First I replaced the shock cord moved it up front. Also I put some clay in the nose cone to provide some weight to lessen the drift weight. The only launch I have done on this was with a c6-5 engine and it worked out great. I think it is a very "tough" rocket that can take a lot of damage." (M.P.S.)

GUEST's OPINION:
06/01 - "I agree that this is an interesting rocket. However Estes needs to reconsider the placement of the shock cord. Mine burned through on the second flight. Come on Estes. Luckily the booster landed somewhat hard into tall grass and was not damaged. I remounted it in the traditional manner with a paper mount and have had no further problems. By the way, launch this rocket when there is no wind or you will be chasing after the nose cone." (D.B.Jr.)

GUEST's OPINION:
05/01 - "I attached the nose cone to the body with a piece of coat hanger. The result was that the entire rocket now descends by the helicopter. I also cut about an inch off of each blade of the helicopter, to bring it down that much faster. This is a very durable rocket, it can definitely take it. And the one-piece recovery makes it easier to find and fly again, and it makes for a prettier recovery." (D.)

SPECIFIC ROCKET TIP:
02/02 - "Put clay in the nose cone to prevent drifting, then there should be no problem, don’t put a lot though, move the shock cord up as well!" (M.S. )

04-16-2007 William Beggs Est SU C6-3 Apogee - Perfect Calm Event: Mile-High Mayhem
- Perfect flight and recovery.
11-23-2001 Donald Besaw Est SU B6-4 Apogee - NC Down 5-10 mph winds - Nice flight. Drifted quite far. Both pieces recovered.
09-23-2002 Donald Besaw Est SU B6-4 Apogee - NC Down 5-10 mph winds - Great flight. Short walk for recovery.
03-17-2004 Donald Besaw Est SU C6-5 Just Past (1-2sec) 0-5 mph winds - Great flight, went maybe 500 feet up. I had a rather long walk to recover the booster and had to walk even further to recover the nose cone. No damage.
12-01-2001 Michael Mangieri Est SU A8-3 not recorded 10+ mph winds - Oooops ... an A8 in a rocket that requires at least a B! She climbed about 40' and deployed the chute about 6" from the ground - took the prize for "Closest to the launch pad"!!!
03-02-2008 Doyle Tatum Est SU B4-4 None - Unknown 5-10 mph winds RIP - It was the consensus of the on-lookers that the ejection charge was terribly weak. Anyway, a lawn dart. She could fly again with some hefty repairs. Status: Lawn Dart
