Multi-Signal Operating Modes

The R12FL supports various operating modes, including RC car lighting control, PWM output for servos/ESCs, and SBUS/CRSF connections for flight controllers. It converts 2.4GHz remote control signals into usable control signals for RC models while providing dedicated light control outputs; users can connect servos, ESCs, and lighting modules directly, or transmit multi-channel data to a flight controller via SBUS or CRSF.

PWM Output

Directly connects to servos, ESCs, or other PWM-compatible devices.

SBUS Output

Transmits data for up to 12 channels to the flight controller using a single signal wire, ensuring simple and convenient wiring.

CRSF Bidirectional Serial Port

Transmits channel data to the flight controller while supporting telemetry data reception (battery, GPS, attitude, flight mode, etc.).

Lighting Control

Automatically controls tail lights, headlights, and turn signals based on steering and throttle inputs; supports strobe, hazard lights, breathing light effects, and power status indication.

Leading Communication Technology with 500m Ground Control Range

Utilizes the FHSS spread-spectrum algorithm with 67-channel pseudo-random frequency hopping to deliver superior resistance against multipath and co-band interference, allowing simultaneous operation by many users in the same area without signal conflict.

Strong resistance to ignition noise from gas engines, ensuring reliable operation for gas-powered models.

Stable control range of 500 meters on water or land.

3ms Ultra-Fast Response

Offers selectable response speeds of 3ms, 4ms, or 14ms.

When used with Radiolink T16D and T12D transmitters and FHSS V2.1 RF protocol selected, supports up to 12-channel signal output.

T16D, T12D Servo Speed Setting Interface

RC8P Servo Speed Setting Interface

Real-Time Signal Telemetry

Provides real-time feedback on signal strength, RSSI values, receiver voltage, and main battery voltage.

Supports main battery voltage monitoring up to 14S (60V) without the need for an external voltage telemetry module.

Built-in Professional Automotive Gyroscope

Provides stabilization corrections for the steering channel; sensitivity is adjustable via the transmitter.

Built-in Simulator Function

The R12FL receiver has a built-in PC Game Joystick communication program. It can be directly connected to a computer via the receiver's Type-C port to use simulators, supporting mainstream open-source simulators such as TRYP FPV, AeroFly, Uncrashed, Liftoff, FPV LOGIC, and Velocidrone (TBS Simulator). No external power supply is needed, and it is compatible with both macOS and Windows.

Currently supported transmitter models include: RC8X, RC8P, RC6GS V3, RC4GS V3, RC6GS V2, RC4GS V2, RC6GS, RC4GS; T16D, T12D, T8FB, T8S.

Receiver Smart Default Mode

By default, the receiver's light board connection ports are assigned as follows: Channel 1 for left turn signal, Channel 2 for right turn signal, Channel 3 for headlight, Channel 4 for tail light, Channel 5 for hazard lights, Channel 6 for strobe, Channel 7 for breathing light, Channel 8 for power indicator.

Dual-Mode Light Board Control

Transmitter Custom Mode

Enter the transmitter's "Light Control" settings page and assign a switch and its trigger position for hazard lights, strobe, and breathing light respectively. Once configured, toggle the corresponding switch to activate or deactivate the specific lighting mode.

Supports 270-Degree Servos

When used with Radiolink T16D and T12D transmitters, the R12FL can adjust according to the servo's maximum rotation angle, preventing gear damage caused by incompatible travel.

After enabling the 270-degree servo control switch, servos from 0 to 270 degrees can be precisely controlled. Robot joints, robotic arms, gimbals, panoramic camera systems, and complex servo linkage mechanisms can all be controlled smoothly, meeting the requirements of more complex application scenarios.

(currently only T16D, T12D support this function)

Reverse-Polarity Protection & Wide Voltage Input

The servo connection channels feature electronic reverse-polarity protection. Even if the power wires are connected in reverse, the receiver will not be damaged. Supports 3–12V wide voltage input, compatible with high-voltage servos.

Power common rail note: The positive power rail on the light output side and the servo channel side are internally connected. The input voltage will simultaneously act on both servos and lights. Therefore, before using high-voltage servos and increasing the input voltage, you must confirm that the lights can withstand that voltage. A 5V input voltage is recommended.

Sub-ID Mode

Rescue, Towing, Parent-child Entertainment, and Friend Teaching in One Control

Capable of designating a subsidiary ID among multiple bound receivers to meet special needs such as long-distance rescue with model cars/boats.

Example of the use of the Subsidiary ID ①: Ship No. 1 is parked in the middle of the lake due to insufficient engine battery voltage.

At this time, ship No. 2 can be switched to tow to rescue.

Example of the use of the Subsidiary ID Mode ②: After the No. 1 trailer consigns the No. 2 vehicle to the designated address. Switch the Subsidiary ID number of the remote control from No. 1 to No. 2 to control the No. 2 car, and let the No. 2 car reverse from the trailer.

USB Mass Storage Mode Online Upgrade

The R12FL can be connected to a computer via Type-C for upgrades. USB mass storage mode makes operation extremely simple, allowing easy addition of the latest features.

Splash-Resistant Design

The R12FL's PCB and pins are treated with the same waterproofing technology used in smartphones — nano-coating technology. Waterproof rating: IPX4*.

*IPX4: According to the IP rating standard recommended by the International Electrotechnical Commission (IEC), IPX4 means that liquid splashed from any direction onto the enclosure shall have no harmful effect.
