Here is a diagram: http://www.answers.com/topic/zap-flaps A well done slotted flap is about 5% better than a plain flap (like on the TR1), a split flap is about 10% better than a slotted flap and a Zap flap is about 10% better than a split flap. On the TR1 a Zap flap would reduce stall and landing speed about 5+ knots. A Zap flap is about the same as a well done single slot Fowler flap. Both are about the same complexity to make but the Zap has nothing critical. With a Fowler the slot size and shape is critical and if not done correctly is not as good as a Zap.
