It is not nearly so simple as adding weight, that works sometimes... but not all, and some "light" planes work very very well, Billy's P-47 weighed 54 ounces and was 700 sq.in, It flies exceptional in the wind, My Katana was 59.5 ounces when it flew in 2 extremely windy NATs with winds approaching 30 MPH, it is 675 sq in
Curt Contrata's SATONA weighed 48 ounces and was 640 sq in, about the same wing that Dave Fitz has in his new ship. It flew extremely well in 20 MPH plus winds, I flew it several times with 2 being in high winds.
I have personally flown other very lightly loaded ships that perform very well in high winds, Bears included. This is not to say heavier ones don't work, just adding some realistic facts to the thread.
The only place where the heavy ships have any advantage over "some" of the lighter loading ones are in the landing, When the power shuts down, sometimes its a B**** to land a very light plane in turbulent high winds.
