Hi, I see people flying 3-D planes very slow and stable. My planes seem to be unstable at these speeds. I always have one wing that tips or stalls. What mods do you make to make this better? I have lightened the plane but this did'nt cure it. I really want to make a rock solid plane here but can't find the right combo. I'm flying the Yak. Please help a confused piolet. Thanks in advance.
