What is a model aircraft receiver?
In the world of model aircraft enthusiasts, the receiver is a vital piece of equipment. It is responsible for receiving signals from the remote control and transmitting these signals to various actuators of the aircraft model, such as servos, ESCs, etc. This article will introduce in detail the definition, working principle, types and how to choose a suitable receiver for model aircraft receivers.
1. Definition of model aircraft receiver
The aircraft model receiver is a wireless communication device used to receive radio signals sent by the remote controller and decode them into control instructions to control the aircraft model. The receiver is usually paired with a remote control and is an indispensable core component in model aircraft flight.
2. Working principle of model aircraft receiver
The working principle of the aircraft model receiver can be briefly summarized as the following steps:
1.signal reception: The receiver receives the radio signal sent by the remote control through the antenna.
2.Signal decoding: The receiver decodes the received signal into specific control instructions.
3.command delivery: The decoded instructions are transmitted to the servo, ESC and other actuators through the output channel of the receiver.
3. Types of model aircraft receivers
According to different communication protocols and functions, model aircraft receivers can be divided into the following types:
| Type | Features | Applicable scenarios |
|---|---|---|
| PWM receiver | Traditional analog signal receiver, each channel independently outputs PWM signal | Suitable for old model aircraft equipment |
| PPM receiver | Combine signals from multiple channels into one PPM signal output | Suitable for scenarios where simplified wiring is required |
| SBUS receiver | Adopts digital serial communication protocol to support high precision and multi-channel | Suitable for modern model aircraft and multi-rotor aircraft |
| IBUS receiver | Similar to SBUS, but with different communication protocols and better compatibility | Suitable for remote control systems of Flysky and other brands |
4. How to choose a model aircraft receiver
When choosing a model aircraft receiver, you need to consider the following factors:
1.Compatibility: The receiver must be compatible with the communication protocol of the remote control.
2.Number of channels: Select a receiver with sufficient channels according to the control requirements of the aircraft model.
3.Dimensions and weight: Small model aircraft require lightweight receivers.
4.Anti-interference ability: Model aircraft flying in complex environments require receivers with high anti-interference capabilities.
5. Recommendations for popular model aircraft receivers
The following are several popular model aircraft receivers on the market recently:
| Model | brand | Number of channels | Communication protocol | Price (yuan) |
|---|---|---|---|---|
| R-XSR | FrSky | 16 | SBUS | 200 |
| Flysky FS-iA6B | Flysky | 6 | PPM/IBUS | 150 |
| Spektrum AR620 | Spektrum | 6 | DSMX | 300 |
| TBS Crossfire Nano RX | TBS | 12 | CRSF | 400 |
6. Summary
The aircraft model receiver is the core equipment in model aircraft flight, and its performance directly affects the control accuracy and flight safety of the aircraft model. Choosing the right receiver requires comprehensive consideration of factors such as compatibility, channel count, size, and anti-interference capabilities. I hope this article can help model aircraft enthusiasts better understand receivers and choose products that suit their needs.
