The rudder use is not the problem. As a former licensed pilot, I can certainly see the value of a crab in a crosswind. It's just that in certain light conditions with a tree background I just can't tell how far I have drifted toward the other side of the field until the plane is almost on the ground and then a severe correction is needed which doesn't make for a "pretty" landing. So far I have not missed the runway, but it has been extremely close a couple of times. I haven't damaged anything yet either and I want to keep it that way.
