I just got an Inspire 2 and have the loose red prop syndrone. (Pun?)
I founf a different fix that I believe is working.
In looking over the parts to the spare set of prop mounts sent with the bird, I noticed that the outer retainer clips are interchangeable. What isn't is the plate that the prop actually sits on.
So, being a tinkerer, I tried switching one, and guess what? It works!!
I happened to have some 1345LS kits that I had bought as spares for my Inspire 1, which is where I got the second one from.
Now, both reds are tight with no rattle or more importantly, no vibtation.
The inner plate is what I use to tell me which prop goes where and disregard the white marks on the outer retianer rings.
Problem solved....

The 1345LS hubs are the sane? I have seen this before on one of the other threads and they used the white hubs and painted them with red nail polish.

This is a nice tip nevertheless

Yes, the outer rings are the same, just the inner plates are completely different.
I will probably just black out the white marks with a sharpie. The inner hub still has the correct color marking.

Nice Idea, got to check if I have some I1 parts somewhere too.
Hope DJI takes notice, its just been too long without a proper fix...
