Hi All, I replaced the Ncore in a 1v2, installed firmware (1.11.01.50+) from a Fat 32 formatted card, the log says same firmware version ., etc etc multiple times - until the last line - error. I suppose that's me shutting the bird down.. Anyhow aircraft 1.11.01.50+ app 3.1.42 RC 1.7.80 camera 1.11.01.50+ basic fly safe DB 01.00.01.07 Is there a compatibility list somewhere so I don't ask redundant compatibility questions. --- Start both the rc and bird up, initiate sticks - I get 'ESC error restart or contact blah blah blah'.. Is there a way to check the ESC and / or motors on a bench to know what or which need to be replaced? I've searched through here and can't find any threads on that,, or am not using the proper search terms. (I calibrated IMU GPS Camera, restarted multiple times after saving settings) What else can I do? Thanks.
