BetaFPV 1102 Brushless – 2026 21000KV motor set for Meteor75 Pro II

BetaFPV 1102 Brushless Motor 2026 Freestyle 21000KV Blue is a set of four blue brushless motors intended primarily for replacing motors on a Meteor75 Pro II whoop or building a compatible 1S FPV drone. This 2026 version combines reinforced mechanical construction with an updated winding design for freestyle flying and everyday practice. Product code is 01050027_3.

21000KV and 1S power

Motor speed constant is 21000KV, and the manufacturer specifies a supply voltage of 4.2 V for 1S operation. Maximum power is listed as 35 W per motor, with a maximum current of 9.2 A per motor. These ratings are relevant when selecting suitable motor control electronics and a power system; the motors are intended for a 1S configuration.

An updated winding design improves stator slot fill factor. According to BETAFPV, these motors achieve 15% higher efficiency when paired with GF 1811 three-blade propellers compared with previous designs, along with smoother throttle response. This comparison applies to the motor and propeller combination described by the manufacturer and does not automatically imply an equivalent increase in flight time.

Reinforced rotor housing and shaft

The outer rotor housing is made from a 2000-series alloy, while a reinforced shaft design improves resistance to crash impacts. Each motor weighs 2.85 g, allowing its mass to be factored into a small whoop build.

Shaft diameter is 1.5 mm, and shaft length is 5 mm. Propeller selection requires checking both shaft bore compatibility and propeller clearance within the frame. Recommended options are GF 1811 and GF 45 mm three-blade propellers.

Mounting and electrical connection

Motor mounting uses three M1.4 screw holes equally spaced on a 6.6 mm diameter circle. The manufacturer’s designation is 3 × M1.4 EQS ø6.6. Each motor has 37 mm long 28 AWG wires and a JST1.25-3Pin connector. Before installation, check frame mounting dimensions, wire reach and compatibility with the controller’s motor connectors.

Recommended components and package contents

In addition to the Meteor75 Pro II frame, recommended parts include the Meteor75 Pro frame. Listed electronics are Matrix 1S 3IN1/4IN1, Matrix 1S 5IN1 II and Matrix 1S 5IN1 flight controllers. Recommended batteries are LAVA II 1S 480 mAh, 580 mAh and 680 mAh models.

The package contains four 1102 Brushless Motor 2026 21000KV motors and 16 M1.4 × 4 Phillips screws. Four motors can equip one quadcopter or serve as a stock of replacement motors. Propellers, frame, flight controller and battery are sold separately.
