Here's the problem I have with this discussion first you show me standard white 9450 props but don't say you're using carbon fiber props. Then you mention that you going to change the Naza-M module when in fact you had already done so. So what am I to believe as you are not helping and I am not a mind reader.
Where did you buy those carbon fiber props from online or from an authorized DJI dealer? My advice would be to buy either a new set of 4 9443 or 9450 props from an authorized DJI dealer. By the way, DJI props have are stamped with DJI and the number of the props while aftermarket do not have the DJI logo on them. I have used aftermarket props back 2014 because of the price they were cheaper than OEM replacements for a complete set but proved to be very unstable.
