i am not an I2 owner yet but out of principal i would have it replaced considering the money i spent (will spend) on it i want a perfect precicion unit. something like this is inacceptable... like buying a rolls roys and having to tighten the screws on the tire now and the because it came loose from factory... what am i missing? dji is crazy to just not handle and tackle the problem or i am not seeing it...
If you have a problem with a missed balance prop the likelihood is that they have over torqued the fixing screws that hold the quick release mechanism, but you need to be careful when un-screwing them with a torque screw Driver because the socket that it goes in is very shallow and easy to strip so it would be a good idea to replace the screws when you do this and not overtighten as this has resolved the problem for me at least, also if you have a replacement Quick release mechanism you can try that in addition to the screws.
The problem I found was that the screws were overtightened, this compresses the spring plate under the quick release mechanism and does not allow it enough travel to take up any slack once the prop is fitted.
Don't forget once you have fitted it's back correctly and confirmed this has resolved the problem to put a little thread-lock on the screw threads before you finish and check it again for correct fit.
I hope this is of help to you all!!!
