Thanks for the comments. I agree a bit longer than even I had planned but I really wanted to use the music track I had selected without cropping it.
The video is sped up x2 for most shots to keep it interesting and to cover as much of the yard as possible.
Interesting note - if you ever attempt anything like this - if you ever fly into a bus or similar through a open window be prepared for the drone to move uncommanded up 12 - 16 inches in height from the height it entered .
On entering the drone is 6 feet off the ground , once inside its only 3 off the floor of the bus , so the downwash has more of an effect . Be careful to avoid a collision with the roof
Coupled with the gps being blocked by the roof , the drone will go into atti mode and may be prone to drifting caused by the prop wash in the confined spaces. My advice fly straight in and out , don't dawdle and hover.
