Thanks for posting the photos. I fly alone a lot in the early mornings. This is a great time for me to practice. These photos force me to rethink my habits. I'm carefull but again I am reminded that If I got hurt at the flying field while I'm alone I might be in big trouble. I had a spinner fly apart while I was adjusting the needle valve last summer. I did not have the proper alum spinner I needed so I went with a plastic one to test a new bird. I normaly never use plastic spinners but the engine was "only" a 91 2-stroke. Lots of sharp edges barely missed my face. Next time could be a different story. We can gain from your personal experience. I hope you have a speedy and complete recovery.
