Well, theoretically, I guess. I mean, if your airspeed is 20mph into a 10mph headwind, it'll take you twice the time to get there compared to no headwind. So the motor will run twice as long. (But not any harder... no more watts) But you always have to come back, so then you're doing 30mph ground speed on the way back, but the plane STILL thinks it's doing 20 mph. Imagine a boat is a large flowing river (ignoring wind resistance of course) going upstream and downstream.
