Brushless Drone Motor Set BETAFPV 1102 18000KV, 4 pcs, 45 mm stator length

Set of four BETAFPV brushless drone motors model 1102 with an 18000KV rating and a 45 mm stator length, intended for compact racing and micro FPV multirotors. The motors deliver high RPM and quick throttle response in a lightweight, space-efficient package. Supplied as a complete 4-piece set for building or replacing motors on compatible micro quadcopters and small racing frames.

Advantages

The BETAFPV 1102 18000KV motors combine a high KV rating with a 45 mm stator length to produce rapid acceleration and elevated top RPM while keeping mass and size low. Brushless design ensures improved efficiency and durability compared with brushed alternatives. The compact construction and standardized mounting pattern simplify installation in micro frames, and the set of four ensures matched performance across all motors for balanced flight characteristics.

Suitable for

• Micro FPV cinewhoops and toothpicks where high RPM and low weight are required
• Indoor and outdoor small-frame racing multirotors
• Replacement motors for 1102-compatible builds
• Prototype and hobby projects requiring a compact, high-speed brushless motor set

Key specifications

• Motor type: brushless outrunner
• KV rating: 18000 RPM per volt
• Stator length: 45 mm
• Quantity: 4 motors per set
• Design: compact, lightweight for micro frames
• Intended use: small racing and FPV multirotors

How to use

Install each motor on the compatible micro frame using the motor's mounting holes and appropriate screws. Connect the motor wires to electronic speed controllers (ESCs) that match the motor's voltage and current requirements; verify correct rotation direction and reverse motor phase if necessary to achieve proper thrust orientation. Balance propellers and use recommended prop sizes for the frame and motor combination. Calibrate ESCs and flight controller settings after installation to ensure stable PID tuning and safe operation.

Recommendations

Use battery and ESC combinations rated for high RPM and continuous current suitable for small racing setups. Select lightweight props that suit an 1102-class motor and avoid oversized propellers that can cause excessive current draw. Regularly inspect motor bearings and bell for debris and maintain secure mounting to prevent vibrations that affect flight performance.
