UGLY! Put it in hard today. I was putting along real easy and the horizontal stab flew off. I thought it had broken at first because I've read about that happening. I had no pitch control so I leveled the wing and shut the engine. It porpoised down and wouldn't you know I was lucky enough that it landed during one of the "porpoises" while straight down. Slammed the spinner into a rock. I took a crash site photo with a camera phone so it's not a great photo. The most sickening part of it? I think it was my fault. This is a new build so I've been checking fasteners for tightness. I've neglected this one and I didn't Locktite it because I wasn't sure if I could transport it without removing it. No more than 10 flights on it and I let this happen. Crap-Ola!!! Live and learn.
