Good comments on wing loading. My second and third RC Airplane years ago were a high wing Kadet Senior and a low wing Craft Air Scout. Had them both flying at the same time and the low wing Scout was a much easier to fly airplane than the Kadet as the Scout had a bit higher wing loading, tracked better, and was overall more predictable than the Kadet that had very light wing loading. A lot of factors go into airplane stability and ease of flying so it is more than just high wing versus low wing.
