Review on 🔧 DJI Phantom 4 Pro Part 4 - Quick Release Propeller Mounting Plates: 2CW+2CCW for Enhanced Drone Performance by Tiffany Allan

My White propellers are extremely difficult to repair on Phantom 4 Pro V2. Some suggested replacing these parts, but I couldn't tell any difference. Still extremely difficult to lock and unlock with motors. No problem with black props only white props. If you look closely there is a tiny white plastic tab inside the white propellers which is not visible on the black propellers. The tongue can be the main reason for a poor fit. In any case, be sure to press very hard and know which way to turn to lock or unlock. Perhaps the fit will weaken with more wear. I tried two other white propellers and found that one was easier to fit and the other was more difficult. The 1 inch strip of silicone rubber wrapped around the motor is said to make it easier to stop the motor from turning.
