RP3 ELRS Receiver 2.4GHz ExpressLRS Nano Receiver FPV RX Module Receiver Long Range Low Latency for FPV Micro Drone Racing Drone Quadcopter

Radiomaster makes some of the best receivers for the money. I’m continuously impressed by the ERLS standard. I was able to update to ELRS 4.0 and set my bind phrase all over WiFi, and then it just works with all my transmitters like magic. If you’re coming from any other radio standard, you won’t regret it.

I'm new to the RC hobby and these ELRS devices have completely amazed me. It's incredible that such a tiny receiver—smaller than a quarter—can host its own Wi-Fi network (which is used for configuration). Setting it up was straightforward, and it paired immediately with my TX16S once configured. I'm currently using this receiver with multiple RC robotics platforms, converting received channel states to CRSF and then decoding via an ESP32 using the AlfredoCRSF library (just make sure to handle logic level differences if you do this on your own). Performance-wise, it's been flawless. One thing to note is that only the first four channels support high bitrate, and channel 5 is reserved exclusively for an "armed" boolean state. There seem to be ways to bypass this limitation, but I haven't explored those yet. Overall, this receiver is fantastic, especially considering its price and functionality.

Radiomaster gear is legit and the RP3 is an amazing value. I've got one and putting another on another FPV quad as I write this. Rock solid. It's been so reliable that I almost forget to check my radio link telemetry because I never have any link issues. You can fit this tiny thing into almost any size quad without sweating it and know that you'll have unbeatable range and reliability. No need for me to check out any other brands.

It's RadioMaster, it's good quality for cheap prices. I've used nothing but RM and ELRS since upgrading my radio from an old Spektrum after getting back into the FPV hobby in the the last year. Yes it's Open or EdgeTX and yes it's ELRS, yes it's a pain and requires a lot of tedious steps and a mountain of knowledge to make everything work, but I've never had to redo any of it because of a RM hardware failure. And the range...... It's never left line of sight.... but if it had, it had excellent range, even for 2.4ghz at lower, completely legal power levels and 500hz framerates on a RM Nano Ranger backpack module on a Zorro. Just make sure you hook it up to a 5v pad, some FC diagrams will show CRSF going to a 4.5v pad, it will not work at 4.5v like another brand.

My favorite Rx. I own about 30 of these and they are all dependable. Never had any issues
