Just flew my new Carbon Cub RTF yesterday. We had a light cross breeze of 10 -15 mph. I had a very hard time fighting the breeze with this lite plane. Has anyone ever added weight, on COG, to give it a little more mass. If the motor has enough power I don't see why it couldn't fly with a little extra weight on board. I am from South Dakota so yesterday is about as calm as it gets.
