I am getting a Topology error when trying to fly my DJI Phantom?

Q. I am getting a Topology error when trying to fly my DJI Phantom?

A. There are a number of sensors in the aircraft, and the computer users information from all of them to fly safely. There is a chance if the compass has encountered some kind of interference it is also causing the Topology error.

You are advised to perform the following:
1. Update Phantom Firmware
2. Run Advanced IMU Calibration
3. Outside away from any metal object perform compass calibration
