Replacement Propeller Pair for Atom 4K Drone by Sanjoyo, Model AT-PROP, 1 Pair

Replacement propeller pair designed for the Atom 4K drone by Sanjoyo. This pair of rotors restores lift and flight stability for Atom 4K models after damage or wear. Supplied as a matched pair, the propellers are shaped and balanced to meet the rotor size and mounting fit required by Atom 4K drones and enable quick swap-out during routine maintenance or in-field repair.

Advantages

These propellers are manufactured to provide consistent thrust and reduced vibration for smoother flight characteristics. The matched-pair supply ensures balanced performance across the affected motors. The design allows for straightforward installation without the need for complex tools, which helps minimize downtime. Materials and finish are chosen to resist minor impacts and maintain aerodynamic profile for reliable lift.

Suitable for

• Replacing damaged or worn rotors on Atom 4K drones
• Routine maintenance to preserve flight stability
• Hobbyist and entry-level aerial photography missions
• Field repairs where a quick propeller swap is required

Key specifications

• Pack contents: one matched pair of propellers
• Compatibility: designed for Atom 4K drone rotor size and mounting fit
• Construction: lightweight molded rotor blades for balanced rotation
• Finish: smooth aerodynamic surface to reduce drag and vibration
• Installation: quick-fit design suitable for tool-free or minimal-tool replacement

How to use

Before installation, power off the drone and remove the battery. Inspect the motor mounts and surrounding areas for debris or damage. Remove the remaining damaged propeller according to the Atom 4K manufacturer instructions, then align the replacement blade with the correct motor shaft and secure it following the drone's mounting direction markings. After both propellers are fitted, perform a brief ground test at low throttle to confirm secure seating and that there are no abnormal vibrations before normal flight.

Usage recommendations

Keep a set of replacement propellers on hand for quick swaps during field flights. Regularly inspect propellers for nicks, cracks, or warping and replace pairs rather than single blades when significant imbalance is detected. Use propellers intended for the Atom 4K to ensure compatibility and safe flight behavior.
