Sorry to hear about your mishap. I too had similar experience with a Hobbistar 60. I was cleaning it at the end of the flying day with it sitting on the bench. I got distracted for a few second to hand to a flying buddy a screwdriver or something. It wasn't a particularly windy day, but wouldn't you know it, a freak gust of wind kicked up in that moment I was away from my plane - and off the bench it went.

Now I NEVER leave a plane unattended unless it's sitting on the ground.
