Has anyone ever had all 4 props spin off in mid flight? Went for a late afternoon flight today and after reaching my 1900 M distance limit I rotated 90 degrees to the right and then began the trip home flying sideways to film a new subdivision. After about 50 meters or so my FPV video went to all snow instantly and after a short minute I flipped to F/S to try and initiate the RTH. A few long minutes passed and after no sign of the Phantom returning, I decided to get in the truck and go track it down. I drove to a point where I knew I was close to when I lost FPV video and within a few minutes located the Phantom on the ground. When I picked the phantom up I discovered one of the motor housings was missing as well as all four props. Not even broken pieces of a prop anywhere. After a quick search of the area I found all 4 props in perfect condition and all 4 relatively close to each other....... but 35 meters or so away of where the phantom came to rest. Not sure if the motor housing came off in flight or came off due to the impact with the ground. I may go back in the morning to see if I can locate it. It appears that all 4 props departed the quad in flight at the same time and landed fairly close to each other.
I am thinking that maybe a sudden loss in power shut off the video tx and maybe stopped the motors abruptly causing the inertia of the spinning props to spin themselves right off the motors. Can that even happen? The Battery showed 11.4v or 70% at the time of FPV video loss and after getting back home still had 2 bars or half charge left. I was not ascending or descending at the time only flying sideways to the right. At 50 meters high there was no collision with anything on the ground (buildings, trees, or power lines) and no sign of hitting a large bird of any kind.
Can someone with more smarts and experience than me shed some light on what might have happened? I want to learn from this to hopefully prevent it from happening again, and to help others avoid it as well.
