Quest ZenithBrief:
This is a two-stage payload rocket. Kit says dual parachute in some advertising but is only a single chute recovery. Flies on A through C engines.

Construction:
One (1) body tube, One (1) plastic payload section which is red. Three (3) fins per stage both stages use a 18mm engine mount with a hook. Kevlar shock cord attaches to engine mount and pulls up through the body which then attaches to an elastic shockcord to the cute and payload section. Plastic nose cone which must be attached by friction to the payload if payload section is to be used. I glued mine in.

Over all instructions were easy to follow and in a logical order. It is a great first two-stage kit for someone who wants to move on.

Finishing:
Once finished this rocket looks good. Has very nice lines and color scheme and decals are good too. I would reinforce joints though for two-stage launches.

Construction Rating: 4 out of 5

Flight:
Flew in both single-stage and two-stage configurations. As a single-stage it's a great flier. Nice and straight on A8-3 and B6-4. Went really high on a C6-5. In two-stage flight this baby goes out of sight! I would recommend installing a streamer for two-stage flights. I did not do this and the rocket is now a 3/4 mile downrange in a forest somewhere! The C6-0/C6-7 combination gives it a real kick of a flight. Love it so much I am going to get another one.

Recovery:
As I said, the 'chute is good for single-stage flights but use a streamer on two-stage flights! I would use a snap swivel attachment for ease of interchanging these.

Flight Rating: 3 out of 5

Summary:
Great kit, easy to assemble and good step up for someone wanting to advance. Was not sure about the staging process with two hooks therefore not allowing taping the engines together but it fired fine for me.

Overall Rating: 4 out of 5

This rocket took off successfully from my pad on its first and deployed the parachute bang on cue after a C6-0/B6-4 flight. All was well until I got it back...with no nose cone. Don't get me wrong, its a good rocket but if you get it my advice is glue the nose cone on.

This kit would be really nice if it used the old fashioned friction fit method for staging. The body tube isn't large enough to have the sustainer's motor mount recessed into it. The motor retaining clip has to be pressed out against the body tube to insert or remove a motor. This deforms the body tube each time. The deformation cracked and flaked the paint off the rear of my sustainer. If I had it to do over again, I'd chunk the motor clips and just build it the old fashioned way. I give it a 2.5 out of 5 because of this, but would give it at least a 4.5 out of 5 if it used the old motor mount method.

On a whim I built a new 1st stage for my well used Z-II. I made it large enough to take a D12-0 and handle a homemade E9-0. Have made two flights each on these motors. 1400' on the D12 and Rocksim says 2700' on the E9-0/C6-7 combo. I use a streamer for recovery. Engine modification is a no-no but I fly it lone ranger style in a very open field with no one around. I use a twist drill rotating by hand to clean out the plug on a E9-P to the black powder. Am told they don't make an E9-0 as people would try to use it in models that are too heavy. The Z-II is light enough to fly on it and really goes!
