"Works great! As decribed!"

— Paul (5/5)

Good little receivers Super lightweight

"Good little receivers Super lightweight and cheap. I have a bunch of these receivers. I use them in a lot of my planes. I also like the voltage telemetry they give out it’s convenient being able to change settings via Wi-Fi. I will definitely keep buying these. They’re also pretty durable. I’ve crashed so many only one of them I think has broke."

Great receiver for small models!

"Great lightweight, inexpensive ELRS receiver with vbat. Would be nice if vbat was pre-soldered, but easy enough to cut off heatshrink, solder a vbat cable and apply the provided new heatshrink. Also useful for models that have gyro + extra channels, e.g. can be configured with serial on 2/3, and 1 and 4 are still available for things like lights or esc reverse that don't go through the gyro."

— Bryce A. (5/5)

Excellent service, very happy with

"Excellent service, very happy with the purchase .. thank you!"

Great little receiver.

"An ELRS with 4 PWM outputs and built in voltage telemetry. Great for those simple models and reliable enough to use in any model, small, large, cheap or expensive. Don't hesitate, just get at least one to see for yourself."

Great little rx

"Nice Elrs rx put it in a FMS Ranger ,The battery telemetry is great .! Service from RDQ was super fast as always !"

Q&A

I'm guessing I couldn't get the battery voltage off of a 1S battery? Looks like it can only read as low as 4 volts -- or is there a workaround?
No this is meant for 2+ cells.
