Eric, I'll pass this on. Out of the 6-8 Micro's I have, each has bound without a problem. Now, there was one unit I loaned to someone to try that wouldn't bind to his module for some weird reason, but it bound to mine without a problem. I'm not saying you're not having an issue; contrary to the point. Knowing you and that you're one to be maticulous about things, I trust what you're saying. Everyone who I would talk to about this though is at iHobby this weekend and I don't know if they're going to be in the office Monday or not. I'll let you know what I can find out for you.

Just out of curiosity...just running thru things in my mind. The receiver that wouldn't bind you said was in your 1/12th scale. Did you try to bind it with either a receiver pack or with a 6-cell instead of a 4 cell? Everything I have used to this point has been with a 6-cell pack or a 2 cell Lipo. I know people have used the SR3500 with 4-cells, so I don't think that's the issue, just trying to eiminate any possibilities. Also, what servos and ESC's are you using. The more info I can pass on the better. Thanks
