FrSky D4R-II CRASH !!!

The first time the receiver hung FrSky D4R-II copter flew at full speed. lost control. He did not respond to sticks and are not included mode fail safe. Upon impact, the gopro turned off and the video is not preserved. Then I thought that it was not in the receiver.

In this video we just checked the copter. He just hung in the air. Suddenly he just stopped listening to management. And he flew forward. Much luck that no one was hurt.

These were two different receiver. The first was that crashed my. In this video my friend crashed copter. Both worked in the mode of CPPM

PS
With the man in the video, we are not familiar. lucky beggar
