From the lovely whine of those beautiful 3328's and the shadow, it is apparent that this is a CS8 with a 2 axis gimbal. From the sounds of the gimbal it is using the MK FC on the aircraft as the gimbal stabilization and control for single pilot ops. I use it for my nose camera and the servo motor will buzz after gyro initialization until you move the gimbal a bit. Around 28 seconds you here a beep, which means a mode was changed. My assumption is that this could be due to a loss of orientation because of Carefree. Either Carefree was on at takeoff and inadvertently turned off, or the other way around. Either way it looks like it induced a disorientation on what the pilot was expecting his controls to be. His intent most likely was to nose forward toward them, but instead pitched back into the hill until ground impact.
Controlled flight into terrain. Means nothing was wrong with the aircraft just the pilot(s) in command lost situational awareness.
CFIT is also known in the soaring (full scale gliding) community as what happens in you are flying in cloud and hit a mountain. Otherwise known as cumulus granitus. Any.
