Just watched this again and had a thought.
Miniquads are hard to see when trying to follow or chase them via FPV.
Even with LEDs it's not easy in daylight.
If you look at Lees video, the plane has a lot of white on it making a good contrast to the sand below.
I guess it is also bigger and follows a more predictable flight path.
Next mini might get a coat of white paint before it's built.
