Do I need an extra module for it to use the full telemetry capability with a D4R-II receiver? I'd like to use this to set it up with voltage alarms using a Naze32
In a word no - you'll just have to make the appropriate connections from the Naze to the DR-II, and then you'll get the voltage info (as long as you've connected the voltage monitor on the naze as well)
Thanks CK
