I updated yesterday. At 99% complete the gimble began having a seisure (twitching). After 2-3 minutes of watching it twitch the gimble motor was hot. Then I got the message "update failed" so I rebooted both units, as instructed. Upon reboot it wanted to "start" the upgrade again which it completed in a few seconds. I flew it successfully. I've had previous updates indicate "fail" but upon rebooting, everything was okay.
That updating is very strange! I was update v 1.3.50 to this. Last time wasnt that easy, i thought i was bricked hole bird
