This Cub has strip ailerons, but deflecting them upward a tad did help the nastiness a bit. I compared the CG to my other ships and the Cub is the most forward at 29%, my others being between 35% and 39% back. The Cub has the highest wing loading however, and I am convinced it is the twist built into the fuse. I can slip it fairly slow with the nose to the right, but slip to the left and it doesn't hesitate to roll over on its back. Building straight and building light are indeed important in this hobby!
