I have about 5 spektrum receivers that for some reason I can not get to bind to either my dx3s. They are the all DSM2 receivers.... Anyone have this issue? Found a solution?

Not to sound insulting, but are you following the instructions exactly? I haven't had to bind receivers in a while, but it was pretty touchy the last time I did it.

I have has this problem before. I has to send my recievers into spektrum to get updated. this problem seems to be hit or miss.

I ended up sending the older receiver in for repair. I got a brand new out of package to bind. But also had an additional out of package not bind. I am thinking the problem is on the manufacturing end.

I have been doing some research on this and have found a few instances with the same scenario you are talking about. Not sure what the final verdict is, whether it's a manufacturing defect or if something happens with the electromagnetic field (LOL). I have two receivers bound to my DX3R and no issues with either, guess I'm lucky!
