I bought my PA3 last June 2015 and flew it for a couple months. I stopped flying it in Sept 2015 due to some family events, having never upgraded any of the firmware. I'd like to get back into flying it now that things have settled down, but I need to upgrade the PA3, RC, and battery firmware. I'm pretty sure that since everything is so old, I'll have to upgrade using the Micro SD card. I've found the Firmware Update Guide on the DJI.com website. My question ... is there anything available in this forum that would be more helpful (easy to read and in more detail)? I'd appreciate if any of you seasoned pilots could point me to any threads that would be helpful. Thank you.
