When I build a rocket, no matter what configuration (regular, asparagus, fairing, ignorant to aerodynamics), the rocket can get up to the stage where I used to preform my gravity turns (5,000-7,000 meters). As soon as I tilt my rockets even the slightest bit, they flip over. I've tried not even putting a payload on rockets and they all still flip upside down and refuse to point up again. I've tried no payload, limiting the gimbal, limiting the thrust and fuel amounts, etc. The rockets definitely aren't top-heavy, so what's the issue here?
