Hi all,

Could someone point out what went wrong with my flight today?

I've had three successful flight before this and during my last flight, quad copter went into a crazy side drive and ended up breaking two of its arms.

I flew three flights prior to this and they all finished perfect. Upon finishing the last flight, I took Iris+ into my truck, drove to a point where I planned on doing next flight and let it sit out in the open for over 5 mins,

Meanwhile, I uploaded the mission and then I went on to remove the used battery, plug in a new one and wait for a GPS fix again. Once I've had green light, I then flew the drone, put it in loiter mode and ensured that it remained in fixed position and then let it go towards the designed waypoints. This is when something went off and it crashed.
