Guys I crashed brand new X5R Copter/App/Camera/RC was the latest firmware when I was flying (Firmware v01.08.01.40) Had 8 Flights before the crash. Was flying 5 meter high tracking a motorbike on road I got error "Sonar Error Land Immediately", before i could react copter crashed. Scared now to fly with VPS have disabled VPS in all copters. Still going to send copter to DJI for repair, have managed to get Flight log will share it here soon. Hope DJI will repair it free since the crash was system error.
