I have always thought about building something similar, but never got around to it. If you are like me and you are running out of room to put your rockets, then this new product can help you out. It is especially good for rockets that are not able to stand up on their fins.
I will post a full review of the "build" with pictures, etc, when I get it done. You can also check out their press release on the EMRR site at http://www.rocketreviews.com/vendor/press_release_cfm_may212010.shtml.
I believe they are even offering free shipping in the U.S. right now. You can contact Greg at Checkered Flag Models to find out.
