GOOSKY F701 Flybarlesssystem with ELRS Receiver - Night Purple

Goosky F701-ELRS Rotorflight Flybarless Flight Controller

The Goosky F701-ELRS is a powerful flybarless flight controller for RC helicopters, specifically designed for use with Rotorflight firmware. With modern hardware, an integrated ExpressLRS receiver and extensive connection options, it provides a compact and reliable solution for demanding helicopter setups.

Powerful Hardware for Precise Flight Control

The flight controller is based on a fast STM32F722RET6 main processor combined with a precise ICM42688P IMU. This provides sufficient computing performance for advanced helicopter flight control algorithms, resulting in fast response, stable attitude control and a precise flight feel.

Integrated ELRS Receiver

One of the key advantages of the F701-ELRS is the integrated ExpressLRS receiver via UART1. No additional external receiver is required, reducing wiring complexity, saving space inside the model and enabling a clean plug-and-fly installation.

Optimized for Rotorflight

The controller is specifically optimized for Rotorflight firmware and tailored to the unique requirements of RC helicopters. It offers low-latency signal processing and stable control performance for precise flight maneuvers.

Flexible Interfaces and Expansion Options

With a total of six UART interfaces, the F701-ELRS provides versatile connection options for telemetry, external receivers, GPS modules and additional peripherals. Dedicated servo and signal ports are available for typical helicopter applications.

Supported Receiver and ESC Protocols

In addition to the integrated ELRS receiver, the flight controller supports multiple external receiver protocols including CRSF, ELRS, S.BUS, FBUS, PPM, MSP and DSMX. ESC protocols include PWM, Oneshot, Multishot, DShot300 and DShot600.

Telemetry and Blackbox

The F701-ELRS supports motor RPM sensing via ESC telemetry as well as telemetry data such as voltage, current and temperature, depending on the ESC used. The integrated 256 MB Blackbox flash memory allows important flight data to be recorded for setup analysis and optimization.

Power Supply

The controller supports an input voltage range of 5–16 V. The serial port power output provides 5 V at up to 1.5 A for connected peripherals. Please ensure that connected devices do not exceed the total available current.
