I have no idea where you got your "10 knot crosswind" thing, but here's a drone from DJI that has a top speed of 45 mph and a 30 minute endurance.
Try holding a course with 5 pounds of thrust and a crosswind? It’s one thing to stay in the air. It’s a whole other to not end up where the wind takes you. The higher up you go the more the winds aloft push you.
