Meteor75 Pro II O4 Brushless Whoop Quadcopter

The BETAFPV Meteor75 Pro II O4 is a high-performance 1S brushless whoop designed for pilots who want a compact FPV platform with digital HD video, improved stability and strong freestyle capability. Built around the DJI O4 Wide Air Unit, it combines a 159° ultra-wide field of view with 4K/60fps recording and low-latency digital transmission. The updated Canopy II vibration-damping system, lightweight Meteor75 Pro II frame, 2026 Freestyle 1102 motors and GF 1811 3-blade propellers work together to provide smooth flight characteristics and excellent durability. When powered by a LAVA II 1S 680mAh battery, the Meteor75 Pro II O4 can achieve up to 6 minutes of flight time, making it a versatile choice for indoor flying, outdoor FPV and HD aerial content.

Key Features

• DJI O4 Wide Air Unit: The integrated DJI O4 Wide system provides an impressive 159° ultra-wide field of view together with 4K/60fps HD video and high-quality digital FPV transmission.
• Advanced Vibration Control: Canopy II uses four shock-absorbing balls to reduce unwanted vibration and image jello, helping produce cleaner HD footage while simplifying installation and removal.
• Meteor75 Pro II Frame: The redesigned 80mm wheelbase frame uses improved arm bracing and duct aerodynamics to reduce unnecessary weight and air resistance while maintaining excellent crash resistance.
• 2026 Freestyle 1102 Motors: The latest 1102 Freestyle motors feature a strengthened shaft and upgraded 2000-series outer rotor construction, delivering responsive throttle control and improved propulsion efficiency with GF 1811 3-blade propellers.
• Matrix 1S 3IN1 HD FC: Flight controller, ESC and ELRS 2.4G receiver are integrated into one compact electronics platform, keeping the HD whoop lightweight and efficient.
• Up to 6 Minutes Flight Time: Using a LAVA II 1S 680mAh battery, the Meteor75 Pro II O4 can provide up to 6 minutes of flight time under the manufacturer's specified conditions.
• Built for Everyday FPV: The protective whoop frame is designed to handle impacts and is suitable for both indoor flying and outdoor FPV photography.

DJI O4 Wide Air Unit: Immersive Ultra-Wide HD FPV

The DJI O4 Wide Air Unit gives the Meteor75 Pro II O4 a particularly expansive view, with its 159° field of view allowing pilots to capture more of the surrounding environment in every frame. The system supports 4K/60fps recording and digital FPV transmission with latency of approximately 20ms. This combination makes the aircraft particularly well suited to close-range flying, indoor environments and situations where a wide perspective is important for immersive FPV footage.

Note: To guarantee performance, selected O4 Wide units undergo pre-shipment sampling and testing. If you receive an activated unit, this indicates that it has passed the manufacturer's quality assurance process.

Canopy II: Improved Vibration Damping and Easy Installation

The Meteor75 Pro II O4 uses the updated Canopy II to provide improved protection and vibration control for the DJI O4 and O4 Wide Air Units. Four shock-absorbing balls connect the canopy to the Meteor75 Pro II frame, helping isolate the camera system from unwanted vibration during flight. The mounting arrangement also makes installation and removal straightforward. A four-screw fixing system and flexible mounting points allow the camera angle to be adjusted from 15° to 35°, providing greater flexibility for different FPV flying styles and filming situations.

Meteor75 Pro II Frame: Lightweight, Aerodynamic and Tough

The Meteor75 Pro II frame has been redesigned with efficiency and durability in mind. The arm bracing has been refined from six supports to five, while the curved whoop duct design helps streamline airflow and reduce aerodynamic drag. At approximately 5.80g, the frame is around 2g lighter than its predecessor while maintaining the strength required for repeated FPV impacts. The result is a responsive and agile 80mm whoop frame suitable for both indoor flying and outdoor freestyle use.

Enhanced Propulsion: Responsive Power and Better Efficiency

The Meteor75 Pro II O4 is equipped with the latest 1102 Freestyle Motors (2026). Their upgraded 2000-series outer rotor construction and reinforced shaft are designed to improve durability while maintaining strong performance. Combined with the GF 1811 3-blade propellers, the motors provide responsive throttle control, smooth power delivery and efficient propulsion. Pair the quadcopter with a LAVA II 1S 680mAh battery and flight time can reach up to 6 minutes, giving pilots more time in the air for FPV flying and aerial footage.

Matrix 1S 3IN1 HD FC

The Meteor75 Pro II O4 features the Matrix 1S 3IN1 HD flight controller, developed specifically for lightweight 1S digital FPV whoops. The compact board combines the flight controller, electronic speed controller and onboard ELRS 2.4G receiver into a single integrated unit. Its digital-focused design eliminates the need for an analogue OSD and helps keep the electronics compact and lightweight. The integrated BEC and ESC design is intended to provide stable power for the DJI digital video system, making setup simpler while maintaining reliable performance during demanding FPV flights.
