I actually got really good results out of my Quad today.
This hover was done in 15 knots of wind and in poshold it just kept its position like it was glued in the sky.
Then decided to do a range test using just the Raspberry pi 3 + onboard wifi and managed to push to 200 meters. So really impressed with my setup at the moment.
Then decided to do an Auto mission and despite the wind it just stayed glued to the track like it was on rails.
