Default AR7000 will not hold bind ?

I have a DX7 (AR7000 RX), and it will not hold the bind. When I turn off the RX, I need to re-bind about 8 out of 10 times. This happened after I charged the RX battery through the switch jack at 0.5a……did that cause this problem? Any fix…? Thanks

Are you sure the Bind Button, on the DX7, is not being depressed, while you are turning on the Tx? I had this happen because I was leaning the Tx against a shallow wood rail on my flight stand. Each time I would turn on the Tx and when I turned on the Rx, the two would not ReLink until I went through the Bind Process, again. It was just luck that I set the Tx in the same place, twice in a row, or I might not have figured it out so easily. A ReBind was necessary, each time.

Charging the Tx at .5a is not an excessive charge rate, but it is always possible to get a short as you plug the charger jack into the Tx. Usually that kills the fuse before damaging the radio.

Does this happen for just one Model Memory or have you tried more than one Model Memory?
Have you tried other Rx's or a different Tx with your Rx?
Are there any lights flashing on the Rx when it fails to ReLink?

AHHH...I think you're on to something. Normally I but the TX on thr ground...but there was lots of snow, so I had the TX on the side of my flight box (where it leans on the box).....that could explain why sometimes it works and sometimes not...I'll re-try and let you know. Thanks Mark

One of my brand new 6110's kept doing this and I just exchanged it for a new one. I wasn't pushing the bind button in my case. Never did it again with the new one. I have a Futaba tx with DSM2 module.

Or they could have put a sliding door over it.

I had the same problem that BushBarber had. Was working on my plane and was laying my DX7 down in such a way that the bind button was being depressed by the wood rail of the flight stand. Took me awhile to figure it out. Here is a pic of how I fixed mine. I just glued a couple pieces of plastic tubing next to the button.

Also, if the transmitter is too close to the reciever during linking (sometimes mistakenly called binding) or if there's a lot of metal around it will interfere with the linking process
