When it comes to remote-controlled (RC) vehicles and drones, the receiver plays a crucial role in translating the signals from the transmitter into actions. Flysky, a well-known brand in the RC community, offers a range of AFHDS3 receivers that cater to different needs and preferences. In this blog post, we will explore the differences between the Flysky AFHDS3 receivers: FGr4D, FGr4B, FGr4S, and FGr4P.

Type and Design

The FGr4D and FGr4B are both enhanced versions, offering improved features over the classic FGr4S and FGr4P. The FGr4D is slightly larger and heavier than the FGr4B, which is the smallest and lightest among the four. The FGr4S and FGr4P are classic models with similar dimensions and weight, making them suitable for a wide range of applications.

Input Power

The FGr4D and FGr4B can handle a wider range of input power (3.5-9V DC) compared to the FGr4S and FGr4P (3.5-8.4V). This allows the enhanced models to be more versatile in terms of power sources.

PWM Channels

All four receivers support 4 PWM channels, providing ample control for most RC models. This ensures that you can control multiple functions of your RC vehicle or drone with ease.

BVD (Battery Voltage Detection)

Both the FGr4D and FGr4B support BVD, which is a useful feature for monitoring battery voltage and ensuring safe operation. The FGr4S and FGr4P also support BVD, making this a standard feature across all models.

Binding Mode

The FGr4D and FGr4B offer a button binding mode, which is user-friendly and convenient. The FGr4S and FGr4P, on the other hand, use a cable binding mode, which may be less convenient but is still reliable.

Antenna

The FGr4D comes with dual built-in antennas, providing better signal reception and stability. The FGr4B has an external single antenna, which can be positioned for optimal signal reception. The FGr4S has a built-in single antenna, while the FGr4P features a single antenna with a length of 150mm.

Waterproof Rating

The FGr4D and FGr4B have a higher waterproof rating of PPX6, making them more suitable for outdoor use in various weather conditions. The FGr4S and FGr4P have a PPX4 rating, which still offers good protection against water and dust.

Data Output

All models support PWM, PPM, i.BUS, and S.BUS data output formats, ensuring compatibility with a wide range of transmitters and flight controllers.

Compatible Transmitters

All four receivers are compatible with AFHDS3 transmitters, ensuring a seamless connection between your transmitter and receiver.

Recommended Models

The FGr4D and FGr4B are recommended for on-road racing models such as 1/10 touring cars and boats, while the FGr4S and FGr4P are suitable for off-road racing models like buggies and truggies.

Conclusion

Choosing the right Flysky AFHDS3 receiver depends on your specific needs and the type of RC model you have. The enhanced models (FGr4D and FGr4B) offer more features and better performance, making them ideal for enthusiasts looking for the best signal reception and reliability. The classic models (FGr4S and FGr4P) are more budget-friendly and still provide solid performance for general use.

When selecting a receiver, consider factors such as input power range, waterproof rating, and antenna type to ensure that it meets the requirements of your RC vehicle or drone. Regardless of your choice, Flysky's AFHDS3 receivers are designed to provide a reliable and efficient connection for your remote-controlled adventures.
