If you're not crashing, you're not flying. (ok, so this isn't true for the full-scale world, but they cheat -- they put the pilot's life on the line for the safety of the airframe)
Yesterday was a good day for me . . . only lost one prop to an old prop-saver band letting go mid-flight . . . and by lost, I mean, I have *No Idea* where it went to (note to self -- replace those bands regularly!) I also had a nice landing "Bounce" on my staggerwing that could have ended badly, but the gear took the hit, shoved off the ground fine and still had runway to settle back down.
. . . But I've had other days . . . like the one where I broke all three planes I brought and a multirotor -- in succession -- beyond a simple field repair. Done in less than 15min, and nothing good to say about it. It happens. You laugh it off as best you can, but some days that sickening crunch is too much.
In the end, all these airframes have an experation date on them -- I'm not saying fly to crash it, but the only way you can *always* prevent a crash is to never fly again. With practice, you'll have more successes (only leaving the energy behind), but the better you get the more new things you'll start itching to try out, and the more you''ll crash. Perfect sometimes? yes. Perfect always? never.
