In pattern like sport jets ( like Flash, Rebel, bandits, etc ) you don't want much if any washout in flight and these are not the high alfa types of jets anyway for most of the flight , however washout is great for stability and higher AOA on landing. The easiest way to accomplish this is a crow set up on the ailerons (where both ailerons deflect up) . This in effect adds washout to the wing. Some elevator trim is also needed around this... I have played around out also having crow on a switch allowing both wings to "wash out" by use of ailerons... besides just playing around with this to see how it changed the flight envelope, i did not find it worth it... ultimately some airframes are better for high alfa than others
