I've been piloting a P3S since just before Christmas and have not yet experienced a flyaway. In fact, I've actually shown people what happens when the signal is lost by turning off my controller and setting it on the ground. In just a matter of minutes, it comes right back to where it started - with the controller still in the OFF position. The furthest away I've ever had my P3S is 5365 ft - over water. At that point, I lost my video and signal simultaneously. After about 4-5 minutes, here it came. I re-established control and landed. At the very end if this video, where the camera is looking off towards the sunset, I am standing on the bridge at the very top of the screen - a little over a mile away.
Did you accidentally post your message on the wrong thread? This thread is about a Phantom 3 Professional that crashed into the water. (When I initially created the thread, it wasn't clear whether it had crashed or flown away.). I'm about to update the topic if it lets me.
If you're just sharing for the sake of sharing - I guess that's fine - but since you're flying a Standard and this is about a Professional and because this one crashed due to a defect and you're talking about how the RTH feature works when there is a lost connection - it doesn't seem like your post is in any way related to the rest of this chain.
If there's some relevance I missed and this was an intentional post here - can you please elaborate on any point you're trying to make?
