I'm running G4 and like it. However, whenever I fly a plane at altitude near overhead (but still in front of me) the plane will flip over or start severly yawing inward. If I'm way out in front of me it doesn't do it. It seems like the higher you go the farther out in front of yourself it has to be or weird things start happening. I also notice faint bands in the sky when this happens. Is this a setting issue that I can correct? If so, how? Thanks.
