Hi guys, totally new to the Phantom world. I would like to know why my P2 keep blinking red lights during all flight time. I calibrate the compass, I have last firmware updates on P2, RC and Gimbal (Zenmuse). Right after I take off I have the front ligth light red (I think it is normal) and the back light is green but it turn red from time to time (about every 20, 30 seconds) and it blinks rapidilly for 6 or seven times and go green again. I've flight it about 7 times and every time is the same. Is it normal or I should check something? And another thing, since I have a P2, how to know when gps signal is ok? My RC is the new model (with lots of leds near the power button and the gimbal button on top left) Thanks. Sorry about my english.
