Changing it costs a full re-tune, a new ground station workflow and a fresh round of field tests. The three stacks that dominate open flight control in 2026 — <strong>ArduPilot</strong>, <strong>PX4</strong> and <strong>Betaflight</strong> — look interchangeable from the outside and are anything but on the inside. The decisive difference is usually <strong>licensing and vehicle scope</strong>, not feature lists.</p>
