Hi.Apologies for a really noob question, but I simply cannot figure out how to export flight data from my Phantom 3S. The manual advises to connect my quad to my PC then use DJI Go to export the data. However, DJI Go won't run on a PC. I assume I'm missing something obvious.

Any chance of an Idiot's Guide please?

Hello Alan, here is the method.Hope it helps:
1.Connect your drone to your PC with the USB cable through the Micro USB Port under the Phantom Label in the front.
2.Turn on both your drone and controller, connect your phone to your controller and open DJI Go app
3.This option is under MODE_MC Settings_Advanced Settings_Enter flight data mode.
4.You can find the DAT files in the removable USB drive.
