The Armattan Gecko is my favorite quad at the moment and the Caddx Turtle is one of the reasons. I noticed some propwash when I watched the video below so I inreased D by about 10 percent and it's almost gone now.

The Caddx Ratel FPV cam has amazing low light abilities. The 3" quad in this video has a cheap LED flashlight on top and weighs 170g including a 3s 450mAh battery.

Same settings as for the Turtle as before but I had to do some color grading, maybe because it was a bit cloudy.
