CORONA C4SF 2.4G Receiver Transmitter for Futaba SBUS Radios

The C4SF-HV receiver offers a range of specifications and features to enhance your radio control experience. With a voltage range of 3.6V to 8.5V and a maximum operating current of 60mA (45mA when linked), this receiver can handle a variety of power sources. The operating temperature range of -10°C to 70°C ensures reliable performance in diverse environments.

The receiver's latency, a crucial factor in responsiveness, is impressively low, ranging from 13.6ms to 20.4ms. Additionally, its sensitivity, measured at around -95dBm, ensures reliable signal reception. The C4SF-HV's compact design weighs in at a mere 6.2g, making it a convenient choice for your models.

The binding process is straightforward: simply turn on the S-FHSS/FHSS transmitter, keeping it within 0.5m to 1m distance, then connect the battery to the receiver while pressing the F/S button. The red LED will light up, indicating signal search, and the green LED will turn on once the binding is successful.

To set up the fail-safe function, you can configure it on the S-FHSS/FHSS transmitter, similar to the process used with FUTABA receivers. We highly recommend enabling the fail-safe feature to ensure your model's safety, such as shutting down the throttle to prevent uncontrolled flight or movement.

The receiver offers a special mode and a normal mode, which can be toggled by following a simple procedure. With the receiver linked to the transmitter, power off the transmitter, then press and hold the button for 6 to 10 seconds until the green LED flashes. Pressing the button again will switch the mode. In normal mode, the receiver provides 4-channel servo outputs, while the special mode enables S.BUS output on the 4th channel, allowing for expanded servo channel support.

When using analog servos, it is recommended to operate the receiver in normal mode. The S.BUS output feature in special mode is particularly useful for expanding the number of servo channels available on the C4SF-HV receiver.
