New to the drone world. Bought a secondhand Q500 4K from my brother. I flew it with him a couple months ago and it worked fine. I fired it up yesterday, and it would not connect to the ST-10. The main LED flashes red, 3x per sec. There is also a tone that it makes. I tried to bind everything together. I can get connection to the camera, but not the drone. I got all the GUI software download and hooked up today. The "Orientarion Sensor (IMU)"- accelerometer bias out of range. I tried to recalibrate the accelerometer and the calibration failed from timing out. Is there anything else I can try? Thank you.
