hi, I have a brand new never been flown Futaba T12K transmitter and a R3008SB receiver. my question is when I bind the receiver all goes well light stays green. Plug in one servo in any port works great plug in another servo and move the sticks it loses its bind. I've tried several times to bind and the same thing happens. Any ideas on what I'm doing wrong.

Are you sure it loosing it's bind, or could your power source be weak and can't supply the power to run both servos?

You were right it was binding but not enough power in the batteries for more then one servo. with two servos plugged in it would lose its bind. New battery no problem thanks for making me think.

Glad you got it sorted.

Also, FWIW, Futaba uses the term "linking" instead of "binding".
