I bought an ar6200 spectrum reciever to use until I have my ar7000 gets checked. I cannot seem to get it bound to my dx7 radio. I can rebind my ar7000 fine. When I bind the ar6200 the LED's go to solid when pressing the bind button. When I unplug the bind plug, the LED dims on the main reciever and goes out on the remote reciever. Any thoughts? BTW the ar7000 seems to work fine but I do not trust it after the crash.
