Hi all,
Yesterday my phantom 2 crashed (but survived) and i had this crash with 2 other phantom 2 in the same way. I wonder if anybody has experienced a similar situation?
The video of the crash is here : http://www.youtube.com/watch?v=i3lA_uK5VjE
The pattern is like this:
First push the throttle up (to its maximum or not), phantom climbs to a high altitude (in this case it was around 130m). Look around, wander around and then push the throttle down a bit (not fully, just a bit to make it descent at a rate around 2-3 m/s, so it is about halfway down). While it descends (with no or very little wind up there) after a couple of meters, it starts to shake like crazy, the remote becomes unresponsive and phantom 2 crashes.
I lost one of them (fully loaded with gopro 3+, fpv) when exactly the same thing happened on a lake. Last week one of my friends' P2 crashed (by me) doing the same thing (thank god it survived). And now my new P2 did the same thing.
Has anybody had this type of crash while descending? Can it be a kind of firmware error?
The phantom 2 has the stock props, prop guards, avl58 (away from compass), iosd mini, h3-3d gimbal and all of them are connected to FPV hub (the previous ones had no FPV hub). It was at GPS mode (with 11 satellites), all the settings at their factory defaults, IOC is off and this was its 3rd flight (other two was without incidents but no high altitude/descends).
Is there a engine cut off mechanism if throttle is down for a specific time? But from the video you can see the engines did not stop during the crash.
Thanks
Melih
