That is weird. Ive not heard of this before. I have never had any issues like this before. This is not fixing the problem, but could you just plug the servo in while programing and then unplug it anfter you finished programing it? Then you should be able to at least run the FM radio.

I'm wondering if others have seen this problem? I have heard of others having trouble programing their BK controllers, but I cant recall anyone identifying that a servo plugged in to that channel on a Y allowed them to program, or that it is specific rx or tx that causes the problem.
