My 9116 recently took a hard nosedive while fighting a strong gust of wind. The crash resulted in a broken hinge on the first chassis I had printed for the 9116. I have had to glue the hinge back in place and am not happy about how fragile the joint is as it could easily break again on the next (inevitable) crash. I went ahead and redesigned the chassis to address the weak hinge, switch location (which turned out to be a bit of an inconvenience), and battery retension system. The v.2 chassis order has been place, and now the waiting begins. On a side note, as my 9116 ownership continues I find myself relating very well to
