Here's a couple more thoughts to consider. Are you working on fuel, or electric power? Are you trying to bind with the plug in the charge port, or directly in the receiver.Some people have had problems trying to bind through the charge port. Do you have a working bind plug in the "batt/bind port. Step back a few feet. Sometimes you get problems if you are too close to the receiver. If all else fails, call a buddy with a Spectrum transmitter, and see if he can bind your stuff to his transmitter. Finally, I have one "off brand" receiver that take about 30 seconds to bind. Apparently it has to think about it. Good luck, and when you figure it out, let us know what's causing it.
