Features: 4in1 vs 5in1

The BetaFPV AIR G4 comes in two configurations: the 4in1 and the 5in1. The 4in1 version is a lightweight option designed for those who want a straightforward flight controller without additional receivers. Weighing in at just 2.9g, it provides essential components for optimal flight performance.

On the other hand, the 5in1 version, which includes an integrated 2.4GHz ExpressLRS receiver, weighs slightly more at 3.6g. This added functionality allows for seamless firmware updates without the hassle of connecting separate components. The choice between the two depends on your flying style and whether you prioritize weight or integrated features.

2.4GHz ELRS Receiver

The integrated 2.4GHz ExpressLRS receiver in the 5in1 version is a game changer. It allows for separate firmware updates, ensuring you always have the latest features and enhancements. This flexibility is a significant advantage over SPI-based receivers, which can complicate updates and maintenance.

With the ELRS receiver, pilots can enjoy improved signal reliability and reduced latency, making it perfect for both racing and freestyle flying. The integration of this receiver into the flight controller streamlines the build process and reduces weight, a crucial factor for Tiny Whoop enthusiasts.

5A 96kHz ESC

Both the 4in1 and 5in1 versions of the BetaFPV AIR G4 come equipped with 5A rated ESCs running at 96kHz. This high-frequency operation is essential for achieving optimal performance in Tiny Whoop drones. It allows for smoother control and quicker response times, enhancing the overall flying experience.

Direct soldering of motors is encouraged, eliminating the resistance introduced by connectors. This design choice results in better efficiency and performance, allowing pilots to push their drones to the limits without sacrificing control.

G4 Flight Controller

The G4 processor used in the AIR G4 Flight Controller is comparable in speed to the F405, which allows it to handle complex PID loops efficiently. This capability is crucial for maintaining stability and responsiveness during flight, especially in challenging conditions.

With support for a 4kHz PID loop, the G4 processor ensures that pilots can enjoy a highly tuned flying experience. Whether performing intricate maneuvers or racing through tight spaces, the G4 Flight Controller meets the demands of modern drone pilots.

USB C Breakout Board

Another notable feature of the BetaFPV AIR G4 is the inclusion of a USB C breakout board. This allows for easy connection to a computer for firmware updates and tuning. The USB C interface is becoming the standard in modern electronics, providing faster data transfer and more reliable connections.

This breakout board simplifies the setup process, making it easy for pilots to connect their flight controllers without hassle. It is a small but significant addition that enhances the usability of the flight controller.

UARTs

The AIR G4 flight controllers are designed with multiple UART ports to accommodate various peripherals. Both the 4in1 and 5in1 versions feature UART1 and UART4, while UART2 is internally connected to the VTX. The 4in1 version provides an additional UART3 for external receivers, while the 5in1 version has UART3 connected to the integrated ELRS receiver.

This flexibility allows pilots to expand their drone's capabilities easily, whether adding more sensors, telemetry, or additional receivers. It's a thoughtful design that caters to the needs of advanced users.

Why You Should (or Shouldn't) Buy the BetaFPV AIR G4 5in1 Flight Controller

The BetaFPV AIR G4 5in1 Flight Controller is an excellent choice for those looking to enhance their Tiny Whoop experience. With its powerful G4 processor, integrated ELRS receiver, and efficient ESCs, it offers a compelling package for both racing and freestyle flying.

However, for those who prefer minimal setups or have existing receivers, the 4in1 version may suffice. The decision ultimately comes down to personal preference and flying style. If you're ready to take your flying to the next level with the latest technology, the 5in1 version is a worthy investment.

Accessories

The BetaFPV AIR G4 5in1 Flight Controller comes with essential accessories that enhance user experience. Included in the package are a USB C to JST connector for easy setup, a BT2.0 power cable, and a lightweight whip-style antenna for the integrated VTX. These components ensure that users can get started right out of the box without needing to purchase additional parts.

Weights

Weight is a critical factor for any drone enthusiast, especially those focusing on ultralight builds. The BetaFPV AIR G4 flight controllers weigh in at 2.9g for the 4in1 version and 3.6g for the 5in1 version. When comparing the 5in1 to a traditional setup with a separate ELRS receiver, the integrated design provides a weight saving of approximately 0.25g to 0.3g, making it an attractive option for weight-conscious pilots.

VTX Output Power

One of the standout features of the BetaFPV AIR G4 5in1 Flight Controller is its VTX output power. The integrated VTX has shown significant improvements in output consistency, particularly at the 25mW setting. This is crucial for competitive racing, as it ensures that pilots can maintain clear video without overpowering other competitors. The VTX provides output power levels of 25mW, 100mW, 200mW, and 400mW, all delivering consistent performance across the board.

Test Results

The performance of the BetaFPV AIR G4 5in1 Flight Controller has been thoroughly tested, yielding impressive results. The VTX output stability is remarkable, particularly at the lower channels, where previous models struggled. The enhancements made by BetaFPV have addressed earlier criticisms, providing pilots with a reliable and efficient flying experience.
