RadioLink R7FG 7-Channel RC Receiver with Gyro Function

The RadioLink R7FG (Part No: RLKR071007) is a high-performance 7-channel surface receiver designed for RC cars, boats, and crawlers. It is an industry favorite for its dual-antenna diversity, which provides an exceptional 600-meter ground range, and its integrated stability system that makes high-speed drifting and rough-terrain crawling much more manageable.

Key Features:

• Integrated Gyro Stability: The built-in high-performance gyro uses a software filter and PID algorithm to correct steering automatically, keeping the vehicle in a straight line during aggressive acceleration or preventing spin-outs during high-speed turns.
• Real-Time Voltage Telemetry: Capable of returning RSSI, receiver voltage, and model battery voltage (up to 8S LiPo) directly to your transmitter screen. It includes a specialized telemetry cable for easy "plug-and-play" battery monitoring without extra modules.
• Long-Range Diversity: Dual 205mm antennas ensure a stable signal even in high-interference environments, offering a ground-level control distance of up to 600 meters.
• Water Resistance: Features an IPX4 splash-proof nano-coating on the PCB, making it suitable for wet conditions, RC boats, and muddy crawler trails.
• High-Speed Response: Powered by a 32-bit M0 industrial chip, it delivers a 4096 resolution with a lightning-fast 12ms latency for near-instant control feedback.
• Multi-Signal Support: Outputs 7 channels of PWM signal, with the ability to output S-Bus and PPM on designated channels for FPV or advanced setups.

Working Mode & Gyro Configuration:

The R7FG features four working modes. To switch modes, short-press the ID SET button once. To toggle the Gyro on/off, quickly press the button 3 times within 1 second.

• Mode 1 (Green LED): Standard PWM (7CH). Gyro is OFF.
• Mode 2 (Blue LED): PWM (1-5CH) + PPM (6CH) + S-Bus (7CH). Gyro is OFF.
• Mode 3 (Red LED): Standard PWM (7CH) + Gyro ON.
• Mode 4 (Purple LED): PWM (1-5CH) + PPM (6CH) + S-Bus (7CH) + Gyro ON.

Pro-Tip for Crawlers & Drifters:

Pro-Tip: If the gyro corrects the steering in the wrong direction (making the car spin out faster), you can reverse the gyro phase by quickly pressing the ID SET button twice within 1 second. The red LED will flash twice to confirm the phase change. For crawlers, keep the antennas at a 90-degree angle to ensure you don't lose signal when the vehicle is in a steep vertical climb.

Safety Note: Because the gyro performs a self-check on power-up, the vehicle must remain completely stationary for 2 seconds after plugging in the battery. If it moves during this time, the gyro may calibrate incorrectly, causing the steering to drift.
