I agree with Bricks, ELRS is the way to go.
Besides being less expensive and less hassle, ELRS likely going to be more reliable. We know it works.
Why reinvent the wheel?
I live in an ocean of corn. In my early FPV years, I got disoriented & didn’t know which way was home. I still had video & RC control but my battery was empty. So I set it down near a road, got in my car & started driving. When I found my plane, it was about 1.5 miles away. Not too bad for a stock FlySky Tx & Rx using a 200mW video with CP antennas. Granted it was in a very low noise environment.
Lesson, always have an arrow pointing home.
