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.

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.

Nice receiver. Easy to setup. I can’t believe how small it is.

Works perfectly with my RadioMaster mt12 and crsf to pwm board. Fast shipping will be purchasing more in the near future

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.

I have used these in many applications when connecting to flight controllers or Gyro Stabilizers they work perfect in CRSF(Default) or SBUS protocol.

Look i've only been flying drones for 5 months. wrecked my first ever drone (super expensive btw) and in the 3 months or so i have built 3 drones. Every single drone including the purchased drone i have ran elrs and it is phenomenal!!!. Bullet Points.Range: Wow! just wow. 27 miles..thats insanePenetration: tons and tonsLink Quality: exquisiteinterference: haven't seen it yetBinding: really people...it's not rocket science. quit crying like a baby about your inability to bind your aircraft and figure it out. Binding elrs is the simplest process ever.Durability: outstanding.. trust me i've crashed my drones thoroughlyMy point is DON'T BUY ANYTHING BUT ELRS and :Thank me later

I love it. Only i have one problem it won't stay bound. Every time i power it won't bind nor start binding mode even doing three time plug method. I found out that disconecting the vtx does the trick. Apparently is not so much because of receiver fault. Is bcz the vtx draw too much power at the time i plug battery, and receiver won't start properly due to power sag. My problem with the receiver is that it has a physical button but you can push it all day it wont do squat.
