<p>High-performance Open Source Radio Control Link with telemetry and low latency.</p><p><br></p><p>ExpressLRS aims to provide the best completely open, high refresh radio control link while maintaining a maximum achievable range at that rate with low latency. Vast support of hardware in both 900 Mhz and 2.4 GHz frequencies.</p><p><br></p><p><b>Specific for the Gliders and other fixed-wings.</b> &nbsp;Small in form factor, It can be installed in gliders with restricted payload bays such as DLG’s and high performance slopers. Not needing to install an additional altimeter/variometer also saves room and weight.</p><p><b>The built in barometer provides vertical speed telemetry</b>. The variometer sounds both ascending and descending tones, so you will know whether you are in lift or sink without having to look at your transmitter.</p><p><br></p><p>- ExpressLRS wiki for PWM receiver, Click <a href="https://www.expresslrs.org/2.0/hardware/pwm-receivers/">HERE</a></p><p>- Make sure Receiver and TX module both are running ExpressLRS 2.0</p><p><br></p><h4><b>Traditional Binding</b></h4><p><br></p><ul><li><p>Receivers have ExpressLRS fw V2.0 preloaded without BINDING_PHRASE</p></li></ul><ul><li><p>Power on and off your receiver three times</p></li></ul><ul><li><p>Make sure the LED is doing a quick double blink, which indicates the receiver is in bind mode</p></li></ul><ul><li><p>Use the [BIND] button on the Transmitter Lua script, which sends out a binding pulse</p></li></ul><ul><li><p>Receiver will switch to slow blink once it has received binding pulse.</p></li></ul><ul><li><p>Power off and power on receiver again.
