(at around 1 min) The upload date on Lane's video is shown on the computer screen as "April 20th, 2014." This is not the correct date format for YouTube. It should have read "April 20, 2014."
(at around 7 mins) When the group first uses the drone, their conversation can be heard all the way up as high as the drone goes, while simultaneously, no sound from the drone itself can be heard. In later instances of drone footage, we can only hear the drone's own sound created by its blades and it sounds rather loud.
(at around 1h 3 mins) The footage from the drone has audio yet it is clearly shown to be a DJI Phantom which has no microphone in real life. However, a "gopro" like camera is clearly visible mounted on the drone, which is also briefly visible in the following shots; this type of camera has indeed a built in mic.
When the girl puts on the ear camera, her hair covers the camera and yet we see footage from the camera showing a clear view of what's happening.
The X-copter drone is launched by the protagonists several times to view objects in the distance or below, but it never rises more than 10-20 feet above tree level each time. If the group truly wanted or needed to see objects in the distance or at ground level from above they would have had to fly the drone much higher to do so.
(at around 35 mins) James is viewed in a close up and the angle cuts to the reverse angle showing Lisa holding the camera filming him. But James whose POV is where the camera on Lisa is placed is not holding another camera, nor in the next few seconds are any of the other characters holding cameras.
(at around 7 mins) When they first test-launch their DJI Phantom quadcopter drone, the shadow it casts and that is visible in the on-board-footage is by a much bigger hexacopter.
