I'm new to the forum and the Phantom 3, but flying quads and RC in general for awhile. I just picked up a new P3 advanced and love everything about it.. I have had a number of flights so far, It works great no issues. That brings me to my question, I have been reading about Phantoms going crazy, having crashes, etc.. all after the owners upgrade the transmitter or the firmware.. So know I am wondering if I should upgrade anything at all? I have also heard that if you don't upgrade then eventually either the P3 or the transmitter will just stop working.. So for all the experienced pilots on here, whats the deal? what have you guys done?
