I picked up a Das Mikro rx and it works great on FH3. Had a problem with DH4 and could care less. I bought two RX-472 that would not bind, and at least this one does. I will not buy another new or used RX-472 when I know this one will work. Plan on buying at least one more. I checked the range and it is fine, over 200 feet. I had a rough week having two rxs fail and a soldering iron, but all is good now as I replaced them.
