Features

1: Japanese NSK bearings ensure smooth and silent operation with exceptional durability against impacts.

2: Customized N52H high-temperature resistant arc-shaped magnets provide stronger magnetic force and increased pulling power.

3: The motor employs a multi-strand winding method, achieving higher slot fill factor, resulting in a 4% longer flight time compared to single-strand motors.

4: The addition of a dual-security fixation with both circlips and countersunk screws at the bottom ensures a sturdier and more impact-resistant shaft.

5: The M6 stainless steel shaft is compatible with most propeller mounting holes available in the market.
