Darda cars and darda race sets are similar to matchbox or hotwheels cars except they are powered by the amazing spring coil "Mega Motor". The mega motor propels the model cars at up to 30mph, over distances of 75 feet (this is a scale speed of over 600mph!). The "Mega-Motor" cannot be over wound, and requires no batteries or electricity. It is wound by pressing gently on the car and moving it backwards and forwards. The set has 4 loops including a racing car. The roadway length is 6,40 m and the setup dimensions are 125 x 50 cm.
