16km out! Walksnail pb with AtomRC Dolphin

The other day i decided to check if i can beat up my personal best mid range with my beloved wing- AtomRC Dolphin.
This is my fpv feed, from walksnail micro vtx. I decided to turn around becouse was afraid of wind blowing against me on the way back. I could have gone 2-3km more.
I am using my friends tool to generate osd on dvr: github.com/kir...
