BETAFPV 1102 Brushless Motors (2026) – 21000KV, 1S, 4-Pack

Whoop motors take a beating, and the BETAFPV 1102 Brushless Motors (2026) are built for it. These 21000KV, 1S motors have an upgraded 2000-series alloy outer rotor housing and a reinforced shaft to survive the hardest impacts. They were designed for the Meteor75 Pro II, so you can crash, swap, and get back in the air.

The performance is up as well: an improved slot fill factor gives them 15% higher efficiency when paired with Gemfan 1811 3-blade props. That means more power, smoother throttle, and a motor that works well for both freestyle and cinematic flying. At just 2.85g each, they keep your 75mm whoop light and agile.

Each pack has 4 motors and 16 screws, enough for a complete motor set with spares.

Common Questions

What do these motors fit?
They're designed for the BETAFPV Meteor75 Pro II. BETAFPV also lists the Meteor75 Pro frame as compatible. They mount on a 3× M1.4 pattern with a Ø6.6mm spacing.

What props should I use?
Gemfan 1811 3-blade props, or Gemfan 45mm 3-blade props. Both have a 1.5mm shaft hole to match these motors, so don't use 1.0mm-shaft props from smaller 0702 motors.

What's new compared to older 1102 motors?
The 2026 motors have a stronger 2000-series alloy rotor housing, a reinforced shaft for crash resistance, and a better slot fill factor. Together, that gives you 15% higher efficiency with Gemfan 1811 props.

Do I need to solder them?
Not on boards with matching plugs. Each motor has a JST1.25 3-pin connector, so they plug straight into boards like the Matrix 1S 3IN1 and 5IN1 II.

Which screws should I use?
The pack includes 16× M1.4×4 screws. Always match screw length to your frame's recommended motor screw. For example, BETAFPV lists M1.4×3mm for the Meteor75 Pro II frame. Screws that are too long can reach the motor windings.

What flight controller works best?
Pair them with a 1S flight controller whose ESC can handle the current. The Matrix 1S 3IN1 and 5IN1 II, both with 12A ESCs, are BETAFPV's recommended partners for these motors.
