HelloRadioSky HR7E 2.4GHz ELRS 7CH PWM Receiver for Fixed Wing RC Airplanes, Drones & FPV Quadcopter

Overview

The HelloRadioSky HR7E ELRS PWM Receiver is a compact long-range 2.4GHz receiver designed especially for fixed-wing RC aircraft and other PWM-based models. Pre-installed with ExpressLRS 3.3.0, the HR7E offers up to 8-channel PWM output and can drive up to 7 servos while sending back real-time telemetry. Dual 180 mm high-sensitivity antennas and up to 100 mW telemetry power provide stable control for long-distance flights. With built-in receiver and flight-battery voltage sensing (DC 4.0–35 V) and a 4-pin CRSF port for future sensor expansion, the HR7E is an ideal upgrade for fixed-wing aircraft, model airplanes, RC drones and quadcopters.

Binding Method (Traditional)

1. Power on the HR7E receiver; the LED will light up, then power it off.

2. Repeat the above step two more times.

3. On the third power-up, the LED will flash quickly twice, indicating that the receiver has entered bind mode.

4. On your ExpressLRS-compatible radio, select the BIND function to complete pairing.
