I am working on a PH3 Pro.... Symptoms as follows: ~63% battery life ~App version 2.8.4 ~RC charged - Firmware updated to version 1.6.0 shows green on RC but no control whatsover. If you try to link RC it will go through process solid green on RC but the OFDM shows green with a slow blinking red. ~No image transmission signal error ~Flight Controller status serial number is not showing in the "about" section so no firmware version either ~When powering on.. gimbal does its dance but after a few seconds drops down and does not hold its heading almost like it loses power. No blinking red or green on front of gimbal showing a firmware installation (.bin file only downloaded to the SD. Can't try formatting as it will not let you only shows remaining capacity but no information provided... tried other SD) ~Solid RED leds on front arms... Inside so blinking yellow on rear Any help would be greatly appreciated!
