The first tip might be totally obvious, but I read of people finding drones and asking what to do. So this means the foundlings do not have a label giving the owner's details. Surely labeling your drone should be done even before the maiden flight! My second tip is to spray the plastic gimbal lock a day-glow colour. It makes it more obvious that it needs to be removed before flight and refitted after. It also makes it harder to lose. Clear plastic is so easy to lose on location.
