Revell Spin Drive Turbo Loop for $41.99

Spin drive racing set takes no batteries - and doesn't tie the action down to the nearest electrical outlet. A dynamo in each handheld controller generates power when you turn the crank. The faster you crank, the faster your car moves. Set up a Revell Spin drive race course anywhere you want and just spin to win. No batteries needed. Recommended for ages 8 and up.
