I had a failed antenna to RF board connection (I think I did) and sent in my Tx for repair so even my AR6200 failed at 100'. Funny thing is that I had a bind plug pressed range test of almost paces with that Rx of almost 150'. Range test meant nothing when my signal became intermittant depending on the connection in the joint. At first, I blamed the clone RXs that caused the crashes during range testing on my cheap plane (3 crashes and about $2 in damage). Then it caused $80 in parts on my 500 heli.
I then went back to the drawing board on all my clone Rx testing. Its not always the RX
Incindently. My buddy had an Orange RX futaba lock up on him on takeoff a month ago. The antennas ripped off during the crash so he gave me the Rx housing with board (no antennas) if anyone wants me to mail it to them.
