FrSky TW GR8 Receiver

FrSky TW GR8 Receiver – Dual-Band Power with Precision Variometer for Long-Range Gliding

Overview

The FrSky TWIN Series TW GR8 receiver is built for serious RC pilots who crave long-range performance and unmatched reliability. Featuring the innovative TW active-active protocol, the GR8 uses two 2.4GHz frequency bands simultaneously—unlike conventional receivers that switch to a backup band only when needed. This dual-band, always-on setup means stronger, more resilient signals, perfect for long-distance flights.

Designed with glider pilots in mind, the GR8 boasts an upgraded high-precision variometer sensor, delivering real-time altitude and vertical speed data with impressive accuracy. Whether you’re climbing thermals or descending for a perfect landing, the variometer ensures you stay informed.

The GR8 is equipped with 8 PWM channels, SBUS In/Out, and full telemetry support via FBUS/S.Port. Simplify your setup by running everything through a single wire with FBUS protocol, cutting down on clutter and making it easier to build and maintain. Plus, with Over-The-Air (OTA) firmware updates, you’ll always have the latest features without needing any cables.
