I don't think it's anything, I have gotten that message "motors overloaded" prolly 5 times in the last 15 flights. I'm pretty sure it just means what it says.. I usually get the message when I'm fighting a lot of wind like going head on into wind and full throttle, or zipping around full throttle at long periods of time. I think it's just the quad recognizing that the motors are getting warm from lots of current draw and when the message displays it's letting you know this, and because of it, it limits how much power you can give to the motors so that they can cool back down and then continue working just fine.. It's just a safty feature so ppl don't burn up their motors.
Btw I have not updated fw myself. The drone is almost a year own and I have never done an update. Never felt a need to cuz everything works just dandy
