I love this rocket. It is perfect for fun occasions because of it's colorful painting and fun flying .Just by a little curve in one fin, this rocket will swirl up into the sky very high. It even leaves a little smoke trail of the swirls like a stunt plane. This rocket is also big, it is about 21" tall! Building is easy and painting is a snap with a can of spray paint. I highly recommend this rocket to everyone.

Part of the Estes Beta Series. Excellent rocket for the all rocketeers. Easy to assemble and great fun to fly. 

The Corkscrew has special engine and fin placement, which makes this rocket SPIRAL and SPIN up into the sky. Smoke Trails from the Corkscrew, make it a blast to watch. The kit is easy to assemble as it comes with preformed plastic fin assembly, nose cone and body tube are prepainted. The price runs around $12.00. I like its Color scheme. The body is red and the fin's and nose cone are blue. 

As part of the Rokkit Scientist collection, The Corkscrew is one of the more entertaining rockets. It is pretty cool to see it gain altitude, but the added fun of watching the "rocket acrobatics" on its way up, is well worth the 12 bucks..
