ReadyToSky RS2205 2300KV 3-4S Brushless Motor

The ReadyToSky RS2205 2300KV is an affordable brushless motor for 5-inch FPV racers and 250–300 mm frames such as the QAV250, running 3–4S LiPo. It is a sensible choice for pilots learning to build and fly who want a dependable, low-cost motor set, and it is available in clockwise or counter-clockwise rotation for a matched quad.

Key features

• Cooling fins at the base draw air up through the windings as the bell spins, lowering coil temperature under sustained throttle.
• Curved N52 neodymium magnets with Japanese NMB bearings for smooth, consistent torque.
• Anti-off U-ring retainer keeps the bell secure at high RPM.
• Maximum thrust quoted at around 1,024 g on a 5-inch prop.
• Black cap marks the CW motor, silver cap the CCW motor.

Specifications

• Stator: 2205 (22 mm diameter, 5 mm height), 12N14P
• KV: 2300KV
• Input voltage: 3–4S LiPo
• Maximum thrust: approx. 1,024 g (5-inch prop)
• Shaft diameter: 5 mm
• Motor mount: 16 x 19 mm (M3)
• Motor size: 27.9 x 31.7 mm (diameter x height)
• Bearings: NMB
• Weight: approx. 30 g
• Rotation: CW (black cap) or CCW (silver cap)
• In the box: 1 x motor, 4 x mounting bolts

A quad needs two CW and two CCW motors. When replacing a single motor, match the KV, stator size and rotation of the rest of the set so every arm produces the same thrust.
