Spotlight Review

"Just a few defects"
Over all the rocket was pretty easy to install provided you have some experience. No wood at all on this rocket it's all done with modeling cement so that was nice. It has something that is new to me that I'm curious to see in action and that is instead of the parachute coming out of the nose cone it comes out right at the middle section. Two things I didn't like we're the way the fins and nose cone came out of the cast, the fins needed sanding and some putty to fill right at the base where it came out of the mold ( very easy and just cosmetic) however the nose cone wasn't perfectly round, when standing back you can see a slight slant since one side is slightly more curved than the other, but it's really small and unless you have a ridiculously sharp eye like mine most people will still have a hard time seeing it even after I point it out. But over all it was a good rocket to build.

"Can't get chute to deploy"
Bealutiful rocket, easy to assembly kit; but I've had it with this model. Bought and built two of them, and watched both streamline into the ground without ejecting the chute. The first one was definitely my fault. I didn't use epoxy on the bulkhead firmly at the joining section. I surmise when the ejection charge popped, this diaphragm blew forward and the rocket volume just absorbed the charge... no deploy. Bought another (didn't paint right away) and made sure to epoxy ALL bulkheads tightly. Same thing happened. All bulkheads in place even after darting the dirt. I don't discount that I may have done something wrong, but all my other rockets perform flawlessly, or at least, I know when I've made a mistake. This last flight was a head scratcher... and expensive to boot. 2 rockets and 2 G motors gone. Great stable flight, majestic take off... I just can't get the chute to deploy!

"Used for my level 1 HPR certification"
Nice kit for money, I built it with a longer engine tube so mine ejects at nose cone(not separated in middle as designed) and no engine block. I used it to get my Level 1 and I have flown it several times on H motors. It does fine but it has plastic fins and they do have some flex witch is not entirely desirable under heavy thrust. Painted bright yellow and it is a lot of fun.

What a great rocket! I have flown hundreds of mid & high powered rockets, and this one is too cool. Lets face it, these are simple rockets, easy to assemble. Nothing hard here. When you are done you have a very impressive looking bird. Low performance due to high mass, but this rocket could easily be flown on H power. For killer G flights, get a Mustang. I love mine! I read most reviews of this rocket. FOR HEAVENS SAKE, USE EPOXY ON THESE ROCKETS, And don't skimp on the epoxy. I also built mine with the body tubes EPOXIED together. The nose cone slips into the airframe easier than the coupler, just something I like better.
