I have two logs I need help analyzing from two separate 3DR SOLOs. These SOLOs are located on the other side of the world from us, so looking to see if there are any adjustments that can be made locally, rather than have them shipped back to us in the USA to have replaced by 3DR. Shipping back to us and then back to users would result in large shipping/customs charges. Really appreciate the feedback, thanks guys.

Issue: During a flight, the drone we were using was basically stationary in the air (it was in the process of being turned on the spot) when it lost GPS. The drone quickly became unmanageable. The instructor took over and was lucky to save the drone after some tense moments. It ended in what I would call a soft crash landing, with the drone falling over upon landing owing to the rough surface it was forced to land on. We had already completed four manual take off and landings, and one automatic flight with this drone without issue.
3DR Support's Assessment: Replace the SOLO.

Issue: After flying the mission we landed the drone momentarily. Then took off again, when gaining altitude the drone suddenly lost control over pitch, yaw and roll. The drone flipped over and crashed down into the ground from an altitude about 6-8 m.
3DR Support's Assessment: After analyzing the sensors' graphics we did notice technical problems with the accelerators, this caused that the Solo flown erratically and finally, it flipped. Replace the SOLO.
