I fly my GP Spacewalker in all kinds of wind, and crosswinds are no trouble. The plane has a mag 91 4 stroke on it that replaced the Saito 100 with 9oz of lead in the nose. The Plane also has a big Woody doll in the cockpit. That Plane with that big ole thick wing really likes the weight. You are not going to 3D this type of Plane, and basically just want it to handle well. So my advice is to load it down some, and put it slightly heavy to the nose. Even with the extra weight, my Spacewalker has never even showed the slightest signs of tip stalling on a slow landing. It does weathervane a little in a crosswind, but a little rudder control takes it right out.
