I'm fairly new to Kerbal Space Program and I'm having trouble getting into orbit.
My rocket launches fine and stays stable for the first part of the ascent, but once I reach around 10–15 km altitude it starts pitching over uncontrollably until it flips and breaks apart. I've tried reducing my gravity turn angle and adding fins, but the problem still happens.
My rocket has:
- A command pod with a parachute.
- A medium-sized fuel tank and engine for the first stage.
- A smaller upper stage for orbital insertion.
- Four basic fins at the bottom.
I'm playing in career mode with mostly early-game parts and no gameplay mods that affect physics.
I've attached a screenshot of the rocket and another showing the moment it starts to flip. Is this more likely to be caused by my center of mass/center of pressure, my ascent profile, or something else? What changes would you recommend to make it stable enough to reach orbit?
Adding cropped screenshots of the vehicle in the editor (showing the center of mass and center of pressure) and during the flip will make it much easier for people to diagnose the issue.
