the GPS file is not always exact , at least from what i can see in my GPS files , the closer to ground level you fly the more era in GPS tracking is what i see . don't forget it's using a satellite overlay and it's free . my guess would be at he end of the track , left or right , i hope you find it then you will have two Q's .Yes I went back there again yesterday and tried a few other areas past the lake and couldn't find anything and I did look up in the canopy of trees and nothing at all. Now Yuneec are going to replace the drone I'm very tempted to do a fly by over these areas to see if it picks up on anything. TBH with you if I did find it I would return it to Yuneec as they've held there end and I've been brought up to be honest.
