In case anyone is interest ( this is an old and tired thread ).

At our field ALL of the single conversion RX's, I've tried will glitch because of the proximity to pager and cell phone towers, WiFi and power lines.
This happens when the plane approaches the corners of our flight box.

None of the Dual Conversion RX's do this.

I've had mixed luck with JR "Full Range" ( but they are really single conversion as indicated ) RX's such as the 7x0 & 6x0 series plus others.

Hitecs DC have been great. No problems there too.

But the best find for me were the BP Hobbies Coronas.

The price is right, and I've flown them on everything from foamies through large scale planes w/o problems.

No glitches where the JR' full range RX's have failed...

The JR 610UL series have been a joke for me... glitch, glitch, glitch, glitch.
