Propeller set for DJI Mini 3 drone, Sunnylife, 8-piece replacement blades (model SB7552)

Replacement propeller set for DJI Mini 3 drone, Sunnylife, 8-piece replacement blades (model SB7552) provides a direct option for restoring rotor performance on compatible compact consumer drones. The kit contains eight blades designed to match the blade profile and mounting style used on many small folding drones, allowing users to replace damaged or worn props and return the aircraft to stable flight characteristics. The set is intended for maintenance, repairs, and keeping spare parts available for safe operation.

Advantages

This propeller set is made to the dimensions and balance characteristics commonly required by lightweight camera drones, offering consistent thrust and reduced vibration when installed correctly. The blades are supplied in a complete eight-piece configuration to replace all rotors or keep backups. Using matching replacement props helps maintain flight stability, predictable control response, and safer takeoff and landing behavior compared with using damaged or imbalanced blades.

Suitable for

• Replacement of worn or damaged propellers on compatible compact drones
• Routine maintenance and pre-flight checks to ensure balanced rotors
• Carrying spare blades for field repairs during travel or shoots
• Workshops and repair services performing component-level drone maintenance

Key specifications

• Quantity: 8 propeller blades
• Material: lightweight molded plastic suitable for small drone rotors
• Design: folding blade profile compatible with compact camera drones
• Balance: factory-trimmed to reduce vibration when properly mounted
• Compatibility: intended for drones with matching motor mounting and blade pitch

How to use

Prior to installation, inspect motors and mounting surfaces for damage, dirt, or debris. Replace blades one at a time following the drone manufacturer's recommended procedure, ensuring correct blade orientation and secure attachment. After fitting, perform a motor spin test at low throttle and check for unusual vibration or noise. Conduct a short tethered or low-altitude hover test to confirm stable flight behavior before normal operation.

Usage recommendations

Store spare propellers in a flat, dry place away from direct sunlight and high temperatures to prevent warping. Regularly inspect blades for chips, cracks, or deformation and replace any compromised pieces immediately. Always use the correct blade type and orientation for each motor to maintain flight safety and control precision.
