The K'NEX: Star Shooter Roller Coaster Building Set is a 434-piece set that builds a motorized roller coaster with a steep vertical section, multiple swirls and a loop.
The roller coaster is built around a tower that measure over 3-feet tall. A motor pulls the space-themed coaster car up the steep vertical track and then lets it go at the top to begin its gravity-defying run back down. Along the way, the coaster car will go sideways and upside down along a track that looks like a ribbon. This is one of those building sets that's fun to build and then rewarding when kids see that they did everything correctly and the coaster works.
This set is for K'NEX fans, ages 7 and up.
The directions are pretty good and most people should be able to build the coaster in about an hour.
You will need 2 "AA" batteries to control the motor and they are not included.
