I'm not an experienced pattern flyer, and I've never flown one but I have seen them fly, but a KAOS is a good beginner and intermediate pattern plane. They are still competitive even though it has been around for over 25 years. BUT, it's longivity says something, well okay, a LOT in my opinion, about how well it flies. It is availible in .40 and .60 size. If it were me, I would go with the .40 and put a .60 on it or a .60 and put a .90 on it. You can always throttle back. If you don't already use the throttle, you need to learn to fly 1/2 for level, idle for down, and full for up. It will vary a little depending on the model, you may need to fly at 1/4 or 1/3 for level, that depends on the plane and the engine. Others may dissagree, but over powering your airplane can save it. If you get in trouble, go full throttle, point the nose up and let it climb. If you don't have enough power for unlimited verticle, then someday you will loose a plane because you don't have enough power. I have ended up in more than one tree because I didn't have enough power to climb above them whem I made an OOPS.

Just my opinions,
