Just bought a second hand GP SpaceWalker with a Tower 75. I also find this plane a bear to land. The biggest problem, besides the floating which I can compensate for most of the time, is weathercocking in a crosswind landing. As the plane slows down for landing, even in a slight nose down attitude, the plane will fly into the wind. This has caused some scary situations especially for pilots flying upwind from me. It seems that although it is balanced per the manual that adding weight to the nose might help. Thoughts anyone?
