BETAFPV Meteor75 Pro II O4 Wide 1S ELRS 2.4GHz Brushless Whoop

The BETAFPV Meteor75 Pro II combines the image quality of the DJI O4 Wide system with the power and versatility of a high-performance 1S brushless whoop.

This version comes fitted with the DJI O4 Wide Air Unit and an integrated Serial ELRS 2.4GHz receiver.

It is suitable for flying indoors, through close-proximity gaps and outside in relatively calm conditions.

The Pro II features an upgraded 80mm frame, 1102 Freestyle 21000KV motors, Gemfan 1811 three-blade propellers and BETAFPV’s Canopy II vibration-isolation system.

The result is a remarkably responsive HD whoop capable of smooth cinematic cruising and surprisingly energetic freestyle performance.

DJI O4 Wide Air Unit

The Meteor75 Pro II comes with the DJI O4 Wide Air Unit already installed. Its 159-degree field of view provides an expansive view of the surroundings, improving peripheral awareness when navigating gaps and flying close to obstacles.

The system provides high-definition digital video transmission and onboard recording at up to 4K 60fps. This allows pilots to capture detailed footage without adding the weight and bulk of a separate action camera.

Compatible DJI FPV goggles are required. Analogue, Walksnail and HDZero goggles are not compatible with the DJI O4 video system.

Canopy II Vibration Isolation

The redesigned Canopy II uses four shock-absorbing mounting balls to isolate the complete canopy, camera and air-unit assembly from motor vibration.

Soft-mounting the complete assembly provides more effective vibration control than isolating the lightweight camera alone. This helps reduce shake and jello in recorded footage while keeping the video system securely protected.

The camera angle can be adjusted from approximately 15 to 35 degrees to suit relaxed cruising or faster freestyle flying.

Redesigned Meteor75 Pro II Frame

The Meteor75 Pro II uses a redesigned 80mm polypropylene frame with protected propellers and refined aerodynamic shaping.

The number of frame braces has been reduced from six to five, while the curved duct design helps lower weight and reduce air resistance. At approximately 5.8g, the new frame is nearly 2g lighter than the previous version while retaining the durability needed for regular whoop flying.

The larger 75-class platform provides greater stability and outdoor capability than the Meteor65 Pro II while remaining compact enough for indoor flying.

Powerful 1102 Freestyle Motors

The Meteor75 Pro II is powered by BETAFPV’s 2026-generation 1102 Freestyle 21000KV brushless motors.

These motors use an upgraded 2000-series outer rotor housing and reinforced shaft design for improved impact resistance. Their freestyle-focused configuration provides smooth low-throttle control together with the torque needed to carry the DJI O4 Wide system.

The motors are paired with Gemfan 1811 three-blade propellers, producing responsive acceleration and enough power for energetic outdoor freestyle in suitable weather conditions.

Up to Six Minutes of Flight Time

BETAFPV recommends LAVA II 1S batteries in 480mAh, 580mAh and 680mAh capacities, allowing pilots to choose between lower weight and longer endurance.

The manufacturer claims approximately five minutes of flight time with a LAVA II 1S 580mAh battery and up to six minutes with the larger 680mAh version when flown from 4.35V down to 3.3V.

Aggressive freestyle flying and frequent high-throttle use will reduce the available flight time. Actual performance will also depend on battery condition, weather and configuration.

Matrix 1S 3-in-1 HD Flight Controller

BETAFPV’s Matrix 1S 3-in-1 HD flight controller combines the flight controller, four-in-one ESC and Serial ELRS 2.4GHz receiver on one compact board.

Its STM32G473 processor operates at 168MHz and is supported by 16MB of blackbox memory. The integrated ESC is rated for 12A continuous and 18A peak current.

A dedicated 5V 3A BEC supplies stable power to the digital video system. An independent power supply for the gyro also helps reduce electrical interference and maintain consistent flight control.

Integrated ELRS 2.4GHz Receiver

This version features an integrated Serial ELRS 2.4GHz receiver and is intended for use with a compatible ELRS 2.4GHz radio transmitter.

Serial ELRS allows the receiver firmware to be updated independently without replacing the flight-controller firmware. Binding and configuration are required before the first flight.

Indoor and Outdoor Performance

The Meteor75 Pro II is larger and more powerful than the Meteor65 Pro II. It remains compact enough for indoor flying but provides the stability, speed and momentum needed for outdoor freestyle in relatively calm conditions.

Independent testing found the quadcopter fast, agile and surprisingly powerful for a 1S HD whoop. Its additional weight also gives it more momentum through freestyle manoeuvres than a lighter analogue racing whoop.

It does not have a conventional physical buzzer. The motors can be configured as a DShot beacon, but they are relatively quiet, so care should be taken when flying near tall grass or dense vegetation.
