RadioMaster R85C 5-Channel 2.4GHz Receiver

I ran into issues originally on this receiver but after learning about tuning the signal was able to get it to connect reliably as well as have fail safes in place. If you are having issues with this I would recommend reading through the tuning article on radio master web site. I was able to get FrSky X2 to work by finding the negative signal tuning drop point, and the positive one, then going to the median setting which was around +66 for mine. My Received Signal Strength Indicator (RSSI) stays very close to 100 % with these settings.

I own two telemetry-capable RadioMaster receivers (R88 and this R85C).

I wouldn’t buy another RadioMaster receiver for a few reasons. First off, the range is trash. Like, covering the radio antenna with my hand makes it drop a bar of signal. It completely drops connection after about 150 ft. As if that wasn’t bad enough, there is ZERO failsafe. There’s no option on the radio or receiver. (I did test it on all protocols too!)

The second problem is that if the radio gets too close to the antenna (~1.5ft) it instantly loses connection. The only reason for two stars is because they do support voltage telemetry without another module.

The radio (an MT12) is absolutely phenomenal but the RadioMaster receivers are not at all.

I’m currently using FlySky receivers (IA4B, IA6B, and IA10B) and they are absolutely phenomenal along with the radio.

—Update—
I have seen other favorable reviews of the product and I could probably tune the receiver to have good range and failsafe if I had more time. I have updated the review to 4 stars, because it’s not bind and go like other similar receivers.
