ReadyToSky 1407 4000KV 2-3S Brushless Motor

A 1407 4000KV brushless motor for 3-inch micro quads on 2-3S. The 7 mm stator height gives more torque than a 1404 or 1406 of the same diameter, helping 3-inch props spool up quickly, and the motor is offered in CW and CCW rotation versions for a complete quad set.

Key features

• CW and CCW versions: a quad needs two of each
• 4000KV winding sized for 3-inch props
• M5 prop shaft for 3-inch props with 5 mm hubs
• 18 g per motor
• Compact body, 18.6 mm wide and 29.7 mm tall

Specifications

• Stator: 14 x 7 mm (1407)
• KV: 4000KV
• Input: 2-3S LiPo
• Shaft: M5
• Size: 18.6 x 29.7 mm (width x height)
• Weight: 18 g
• Props: 3 inch

Keep to 3S at most: 4000KV on 4S goes beyond the motor's rating. For a 4S 3-inch build, choose a lower-KV 1407 instead.
