RC cars can't even beat a basic stair or fence, and RC planes are difficult to maneuver as they can't stand still/hover. Try to drop a payload from a flying plane at an exact point on the ground - basically impossible. Even when you do the math, the wind+drag will have a major influence. With a drone you can hit precisely within inches.
