Best ELRS reciever available. What more can be said.

Being a complete noob to ELRS these were a bit tricky to set up. I eventually got them updated and added a bind phrase. From then it was a piece of cake. It seems when binding the traditional way by powering on and off 3 times you need to do it in perfect timing. I got it to bind mode once in the end. I gave up on that and set about updating to the latest version of ELRS which I found a bit tricky, because I don’t have a laptop with wifi… turns out you can just join the receivers wifi hotspot on your phone and log into it via the browser. Easy. Building the actual firmware for the rx was a bit trickier as the configurator would fail each time. I figured I may need to install python onto the win10 machine so did that and it then had everything it needed to complete. Saved the file on the phone, connect to rx wifi, open the rx webpage in browser, run the update with bind phrase and we were good to go. Have yet to test the range but it sounds like they can go for way further than I can fly so should be good as.

Great to have true diversity on ELRS

Its so tiny, but impressive , massive range and power on this,

Long term user flying weekly. Very happy with performance. RX does run hot from my experience. Telemetry needed to be reduced to 10Mw to stop Radiomaster Boxer dynamically scaling up it’s TX power to 250Mw+ at very short distances (50-100m). Once Telemetry power reduced i’m having zero issues at 1.5Km’s at 25Mw TX power.
