two good planes and two different styles..I learned pattern on a kaos and am still fond of it.a great pattern .if you could get a joe bridi one which of course is next to impossible you would own a fantastic plane.smooth and relatively easy to fly.the other plane works well as a sunday flyer..cant really go wrong either way.but I must admit with all my large planes and aerobatic stuff I still have a soft spot for a kaos especially the super kaos..
