OP, after reading this thread I'm sure many people are curious if you found the mini. Here's hoping.
Well ... from what's seen in the log & knowing how the Rocket Quick shot work I don't think it fully reached it's preset altitude before you pressed the RTH button ... short pressing that during the automated flight aborts the Quick shot & it start to hover ... hadn't you done that, the AC had descended back by it self even though it was blowing away but it didn't.I searched the estimated crash area but couldn't find the drone. It was a field with lots of trees and full of bushes so I can't be sure whether it crashed there or somewhere else.
I got the following data analysis from DJI which supports @sar104's analysis:
1. The aircraft worked under GPS mode; It could not respond to the pilot’s commands well due to the strong wind from the northeast;
2. Flight Time T=02:17, Relative Height H=25.2 m, Distance to Home Point D=61.5 m, there was no pilot input, the aircraft tilted 11.9 degrees forward to resist the wind, but it was still blown away at the speed of 5.8 m/s, which indicated that there was strong wind affecting the aircraft;
3. T=02:20, H=26.0 m, D=76.1 m, RTH was triggered by the pilot. The pre-set RTH height was 67 m and the aircraft started to ascend;
4. T=02:54, H=66.7 m, D=181.7 m, the warning of “Strong wind warning. Aircraft unable to fly stably. Lower altitude immediately and manually return to home" appeared;
5. The aircraft was blown away from the Home point by the wind and it could not RTH normally. T=04:29, H=66.9 m, D=441.7 m, the flight record ended;
6. The home point: 40.3214782 28.9122262; The last recorded point: 40.3178336 28.9101530.
According to the analysis, the incident was caused by an improper flight environment. Please do not fly the aircraft under the high wind conditions.
I realize that I shouldn't have flown the aircraft under windy conditions and it's my fault losing the aircraft, but I just want to be sure that this accident was 100% my fault.
A couple of points that I don't understand:
I was trying the Rocket quick shot mode and after the aircraft reached the preset altitude it started drifting away (15 seconds after take-off). I lost control at that point and couldn't switch to manual control. Losing control completely, is it somehow related to the quick shot mode I was trying? If I was flying the aircraft manually from the beginning, would the result be similar?
Second thing that I fail to understand is that it was the first flight on my account and I didn't set the RTH height to 67 feet.
All responses that have been posted so far are much appreciated. Special thanks to @sar104 for the analysis.
