Not buying the whole "just replace the props" for the following reasons:
1. If it were a sole prop issue then it would be simulated across all firmware versions since it affects physical properties.
2. it's an imbalance of increased motor speed. (rear speeds up but fronts don't get the same message)
The big issue before the update was fly aways during high winds, so i believe that dji increased the motor speed paramaters to counter this. Unfortunatly it looks like the alterations were imbalanced resulting in increased speed on just one prop instead of all. I'm not saying the props are not an issue but the trying to pin it on as single cause (props) is inaccurate from what i see.
