When I first had this issue, I contacted Jake to see if he could make a 3D printed insert to firm up the connection.
Jake replied surprisingly fast, and suggested using the larger washer, which also took care of the problem I had with the chrome ring slipping off.
After reinstalling with the washer worked out so well, I have been recommending it here to others that were having similar issues with their installation.
This quick response of getting a revised design implemented in just a few weeks, then providing it as a replacement to customers who had a problem at no cost is another great example of why Jake has earned a reputation for great customer service.
Maybe Jake could go and give a seminar for dji customer service employees!!
