Frsky D4R-II vs X4R Low Voltage Test
Channel: N0FPV
Date: 2017-04-24

I wanted to do some testing for 1S applications like DLG and HLG. 

I use a variable voltage setup to slow bring the voltage down and test the effects on the servos and pair of receivers. 

The X4R is rated down to 4v and the D4R-II is rated down to 3.5v on the packaging. 

Both receivers outperformed their ratings staying connected to the Taranis x9d+ down to 2.6v!

Voltage telemetry data dropped out ~3.4v and the servos speed and power seemed proportional to it's voltage. 

Either rx will be great in a 1S application. I will be using an X4R for my 1m Epee DLG build.
