I have lost two fully loaded QR350PRO. Both were put into GPS Hold but they drifted quite far away while I was concentrating on take video. Then I used the joystick to get them back but nothing happened. I eventally panicked and use the return home feature only for the quid to go down on the spot or lose altitude before trying to come home and running into something and getting lost.
I think the return to home button should be re-labled death button. Both of the quads were fitted with brushless gimbals, ilook camera and a propeller guard.
I also lost a small ladybird quadcopter in Perry Park.
One was lost at Barr Beacon park in Great Barr and the other one in Perry Barr Park. The one at Barr Beacon flew over the hedges and into the farm are on the other side that is hard to get to. The one in Perry Barr Park was lost near the M5 underpass area.
