First of all: Welcome to the forums!

What does any other servo do when you plug it in? Do they do the same thing? It might be your trim (I assume steering).

Also, with those BlueBird servos, you really have to set your EPA so it will stop before the mechanical limits of the steering or it will burn up. Those servos, while powerful, don't like to be held back...
