I would like you to qualify this when talking about their warbirds. The new KMP warbirds are the best quality arfs out there, the Spitfire is phenomenal. I have a yellow Spitfire and it is a top gun aircraft, the kmp definitely holds its own in the air though it is a good bit smaller, I just wish they made 80 inch and above. The first KMP warbird was the corsair which was about the same as the CMP one. They both had similar issues with the KMP being a bit better qualty, Kondor however tried to make his customers happy and gave service etc. to his customers. The newer kits, The Spit, Hurricane and Me109 are the best arfs of there size available in my opinion. The cmp are still the same standards as the old KMP series. That being said the cmp can still be made to look and fly well with a few exceptions.

Good Luck
