No matter what I do with my blx185, it will not go into calibrate mode. What's odd is the set button does put it into a setup mode, but it has no effect after it powers up and starts beeping. Even if I press it to go into one of the settings, it doesn't do it, just keeps cycling to the next setting. I don't recall having that issue when it was in my outcast as I did it when I first bought the truck and had 4S plugged into it. But I when I moved it to my stampede, different receiver, it will not go into the settings anymore. Tried another receiver, same thing. Very odd. It seems to work ok though and since I have the program box, I can still adjust stuff.
