Those things need to be safety wired, both the crimped metal end and the rubber flex housing. I only had mine wired around the crimp, Chris Burgess warned me about my hose not being wired when I had him inspect the Arrow Commander after I finished the CLT conversion.June of 2011, Wunderlick drive cable went through my prop. I was at about 10' agl and about 80mph, fixing to do a zoom climb for the onlookers. Jeff Tipton being one of them. As I rolled wings level over the parallel taxiway, I heard a LOUD boom, and my but was coming off the seat. I left a 100 yard debree field on the taxiway as parts come off the gyro. Here is a picture of my prop after 90 hp Mac a full throttle eat my drive cable. The second picture is the piece we found over by the runway, which was stuck in the ground and it was like it was standing up waving at us.
