I recently built a QUAD X Motor Tailsitter without control surfaces . It weighs approximately 2 kg and features very small wings, giving it a profile somewhat like a rocket racer.
The drone flies stably in multirotor mode, but when transitioning to fixed-wing mode, it experiences severe pitch oscillations. I’ve tried debugging this issue multiple times without success, so I’m reaching out for help analyzing the root cause. Any advice or insights would be greatly appreciated
