Yeah I hear what your saying but the place I fly is just on the west coast of the UK and is prone to frequent breezes of 15 to 20 knots. I have other planes that are very lightly loaded and its a bit like flying a kite on a breezy day - I sometimes ballast lightly loaded models like my 1/3 scale Clipped wing Taylorcraft just to make it flyable!! The difference the extra pound and a half of the smoke set up makes it flyable when otherwise it would not be practical. Much better penetration and acurate tracking - the trade off is higher landing speed but with a 1 mile tarmac strip I usually manage to stop before the end of it !!!
