Calibrating the accelerometer on your HGLRC Zeus35 Pro AIO flight controller is crucial for optimal flight performance. Here's how to do it correctly: First, ensure your aircraft is placed on a perfectly level surface. Next, open the Betaflight configurator and navigate to the "Setup" tab. Locate and click the "Reset Z axis" button. Click the "Reset Z axis" button a second time to complete the calibration process. This procedure ensures the flight controller accurately senses its orientation, which is vital for stable and predictable flight.
