Will be building this either tonight or tomorrow night. I was helping my brother-in-law move when he pulled a box out of the bottom of his closet and said, hey you are into rocket stuff, here you go... It was an old school range box from an Alpha starter set that contained two launch pads, two estes controllers, a very damaged alpha, some cobra motors, and this (sealed in bag) twister kit. This looks like a quick but fun little build. My first impression opening the kit was the instructions. It brought back memories of Estes' highly detailed instructions that I remember as a kid (when compared to the one to two sentence multi-lingual instructions you get these days).
