What It Is / How It Works

This is a 2.4GHz RC receiver for RC car and RC boat use. It is compatible with the FlySky Noble F-S-NB4 PL18 transmitter and suits models that use that transmitter's AFHDS 3 system.

Who It's For / Use Cases

RC car and RC boat hobbyists who run an AFHDS 3 transmitter often look for a small, light receiver that leaves more room inside the model. A compact receiver with PWM, PPM and i. bus outputs suits builders who want flexible connections between the receiver and their electronics.

How to Use / Care

1. Mount the receiver with its antenna as far away from any metal parts as possible.
2. Insert the binding cable into the receiver's BIND port.
3. Plug the power cable into any other port; the LED flashes quickly when the receiver is in bind mode.
4. Put the transmitter into bind mode, following its instruction manual.
5. When the LED flashes slowly, binding is complete. Remove the power and bind cables, then reconnect the power cable to the receiver.
6. Check that the transmitter and receiver work as expected; if not, repeat the binding steps.

How to Choose

Start with the transmitter. Match the receiver's wireless protocol to your transmitter system, which here is AFHDS 3 at 2.4GHz. bus are all supported. Size and weight matter in small models, so confirm the mounting space available before you choose.
