Get ready for some high flying action with this Lite Brix Light Up FX Copter 129 Piece Building Set. This action packed set features realistic helicopter sounds, flashing light effects and the rotor really spins! The building system includes special connector pieces to attach the Lite Brix to each other so you can build the model on different angles, and translucent pieces that glow with colour from the LEDs. Each car includes realistic rolling wheels and racing spoiler. Create more fun by adding bricks from other building sets (sold separately), which attach to all Lite Brix. Requires 3 AAA batteries.
