The Slick 360 was designed to fill a gap in the light aerobatic aircraft segment, as the aircraft which dominate this segment, the Yak-55, Zlin Z-50 and Extra 230 have all ceased production, making them increasingly hard to obtain. While other Extras are still in production (260, 300, 300S, 300L and 330), they are fitted with six-cylinder (260/300 hp) engines and therefore not allowed to compete in the AWAC. New aircraft have been created in an attempt to replace these three, such as the One Design and the Cap 222, but they have failed to dominate, purportedly due to their excessively-high aileron roll rates, which, being faster than their flick roll rates, results in the flick roll scores being downgraded. In addition, their small size has made them difficult to judge. The result being that neither of the two new designs has yet managed to achieve better results than the older established designs, with the past five AWAC events being won by the Extra 230, Zlin Z-50 and Yak-55. This was borne out by the winner of 2003 AWAC, who was a French pilot who chose to fly an Extra 230 despite the fact that he had access to the French team's Cap 222.
