The FrSky TFR8-S receiver is a highly compatible and interference-resistant 8-channel receiver that is compatible with Futaba FASST 2.4G controllers and modules. It supports fail-safe protection settings and can be used in conjunction with other FrSky receivers to achieve up to 14 channels.
This manual explains how to bind the FrSky TFR8‑S receiver to a transmitter, configure failsafe protection, and understand the LED status indicators. Detailed steps are provided for pairing, setting up failsafe values, and switching between HS and FS PPM modes.
Additional sections cover compatibility with Futaba FASST modules, specifications of the receiver, and methods to expand the system to a full 14‑channel setup by paralleling two receivers. Installation tips and wiring diagrams are included to help users install the receiver safely in their models. This manual is written in Chinese.
| Voltage range | 4Y ~10V |
|---|---|
| Operating temperature | -10°C to 60°C |

| Weight | 14.9 g |
| Delay (low‑speed mode) | 1.4 ms |
Power the receiver while holding the FVS button; when the red LED turns off and the green LED stays solid, binding is successful.
Both LEDs off = normal operation; both on = waiting for bind; flashing green = signal loss; red flashing fast = HS mode, slow = FS mode; red flashing twice = failsafe set.
Parallel two TFR8‑S receivers (or a TFR8‑S with a TFR8‑SVTFRS) and follow the binding steps; the combined unit functions as a full‑compatible 14‑channel receiver.
