You said all your planes are kits? I currently have 3 planes with another 1/2 built. 2 of those planes are ARFs and 1 (and a half) are kits. When I'm flying the ARFs I don't really give a hoot about them and throw them around the sky but when I'm on the kit built planes I get a bit nervous and take a lot more care. It's probably about the "emotional investment" we get with kit builds. I'd suggest getting a flight sim and get some hours up on that going a bit crazy, and buy yourself a cheap ARF (maybe even one you don't like that much) and throw it around the sky some - get comfortable putting planes you don't care about to a little risk before putting the kits you've worked so hard on back up - it'll give you more confidence in your ability to safely fly the planes you prize.
