CD rainbow is a water wheel designed for pitch back and over shot. a good characteristic was that if it stalled it had time to fill up it’s bucket’s and lift a heavy weight turning slowly.With the bucket like fins it catches so much water to lift the weight.There are 4 types of water feed, over shot, breast shot, over shot, pitch back, and under shot. we did’t use Brest shot because it took a lot of volts to push the water far enough to get caught in the buckets also by the time the whiter hit the buckets it fell out thats when we released to use pitch back
