I try to limit how often I take the props on and off because of that issue. I would probably balance my props more often if my threads didn’t have so much wear. However, they haven’t warn to the point of needing to be replaced yet.
I have a batch 2 which has two piece prop standoffs. The stud that holds the two halves together is only 8mm while the prop stud is 10mm. Last week one of them broke through the 8mm stud so I am replacing all four standoffs with the new one piece design. Then I will have all new threads.
Note: The slipping happened when the standoff broke and the prop hit the frame.
Not sure how many people have a batch 1 or 2 but it would be a good idea to upgrade to the new standoffs. I hate to think what would have happened if the prop hit the batteries instead of the frame.
