Not that it makes any difference to the frustration of the non-fit of Xoar props, but wasn’t the 1st gen quickly replaced due to release issues? Didn’t DJI offer a free 2nd gen replacement due to 1st gen having release issues? I thought I recall a safety campaign.
The 2nd gen added the underside lock that required the plate and the 3rd gen added the underside lock and the metal side release tabs. Actually that must have become part of the motor, or DJI assumed all V2’s updated, because the 3rd Gen updated Locks don’t have that plate, they assume it’s already present on the motor. So if you purchase Gen 3, you won’t get the plates to lock underside hooks of Gen 3.
