Returned to last takeoff point. Yep, power lines w/i 60 yds. Turned on quad & controller, started DJI GO - no takeoff. Under [Aircraft Status] _Radio channel quality / poor; Strong interference, fly wth caution. (OK *******, pay attention).
Went to another area, very large open field. No preflight caution msgs. No pblms till went to 400' alt. Then [Controller signal weak, then Connection lost] went into RTH. Flew low & close - no pblms. Chased a buzzard, 200' up, 1-200 yds out - Predictable signal lost, RTH.
iflyp3s may be rite.
