So DJI recommends a threadlocker as found here: DJI Inspire 2 High-Strength Threadlocker CP.BX.000226 B&H Photo
If one reads the PDF on #263 here: https://tds.us.henkel.com/NA/UT/HNAUTTDS.nsf/web/382795AAF2B4355B8525760E004BEA0A/$File/263-EN.pdf
and go to the bottom of Page 3 on left side, it says this: "This product is not normally recommended for use on plastics (particularly thermoplastic materials where stress cracking of the plastic could result). Users are recommended to confirm compatibility of the product with such substrates."
Amazing that DJI recommends using this stuff at all and likely why their cheap plastics, as on the Phantoms, crack. I wonder about the CF glues they use too on the Inspire 2, but maybe that's what they want for more cash too - that or even they don't read instructions. Sheesh!
Fwiw, Loctite does make one safe for plastic products, but appears DJI doesn't know of it.
