What It Is / How It Works

This Flysky FGR4S V2 receiver is a 2.4GHz 4-channel receiver for RC cars and boats.

Receivers in this category sit inside the model and pass the transmitter's control signals to the servos and speed controller, so the output type has to match the receiver side of the setup.

Who It's For / Use Cases

Receivers of this type suit hobbyists who run radio-controlled cars or boats and want a small receiver that leaves space in a tight model body. Anyone with a matching transmitter and a servo or speed controller that uses PWM, PPM or i-bus signals will find the output they need.

How to Use / Care

1. When installing the receiver, keep the receiver antenna as far away from any metal parts as possible to ensure good signal strength.
2. Insert the binding cable into the receiver's BIND port.
3. Plug the power cable into any other port; the receiver's LED flashes quickly when it has entered bind mode.
4. Put the transmitter into bind mode, following its instruction manual.
5. When the receiver's LED flashes slowly, binding is complete. Remove the power and bind cables from the receiver.
6. Reconnect the power cable to the receiver.

How to Choose

Choose the output type first: match PWM, PPM or i-bus to the servos or speed controller in your model. Check the channel count and the input voltage range against your power setup. Measure the space in the model, since the receiver body is 26 × 22 × 17.3 mm.
