LoudThunder
Part 107 Licensed
I have a friend who used the sun screen from his car, it was one of these that are spring loaded to open in a full circle. It is very light weight and the first time he was coming in for a landing; between the light breeze and his propeller wash, the sun screen flipped up and hit his drone and it broke a propeller off, and the drone tumble to the ground and broke another couple of props.There are some reasonably priced ones made just for drones. And a scrap of carpet or plywood works just fine, too.
Whatever you use, be sure it stays planted…
