In San Diego, sent it to the LA repair address, hit an inside wall very slow, minimal scuffs on props, no marks at all on drone. After wall collision controller would not recognize drone. Dji has not stated the broken part or the fix.
See below for their response as to conditions. Issue is I had no controller input and it started moving forward.....
And the RTH never worked right from day 1, when returning it was always 15-20 feet off.
1. Unit was in Atti mode due to low satellites, and was responsive to RC input.
2. At t=53s, relative height=0.6m, unit recorded external impact, then fell.
3. Unit was flying with no satellites, mixed with no gps the vision position sensor cannot perform properly. Please refer to manual on factors which can affect vision position sensor performance.
