I just want to point out, I've had over 30 flights now with the devils "NON DJI" alloy hubs, and have not witnessed any so called "severe damage the aircraft’s propellers, leading to potential safety issues due to the lack of self-lubrication, or cause damage through their rough surfaces, hardness and sharp edges"
What I have witnessed on an Inspire that had done 50+ flights with DJI hubs and props was abnormal wear to the lugs on the hubs, and while there was no wear to the props, the hubs could have failed on the next few flights..
As a qualified structural engineer with over 25 years experience in metallurgy, I find it totally unacceptable for DJI to release a statement like this when they know very well their own hubs are failing mid air due to abnormal wear and high load... DJI themselves use dissimilar plastic materials - its clear the hubs wear before the props, meaning the props are a harder material..
DJI, you looking like a pack of Amateurs..
