hey guys I'm trying to bind my 471 airtronics receiver with my 4x4 sct

my throttle reverse and Brake work fine but my savox 1258 servo wont work right. As soon as i turn it on it jumps to the right and locks. It wont do anything. I broke one servo already because it turned so hard to the right it locked it up. So i got another servo and turned all my epa's down to avoid that.
Still turning to the right and i dont know what to do.

Brand new esc brand new servo brand new reciever.

Any help?

This is an easy one.
Dont put the horn on the servo.
Turn it on and then line the horn up where it's in the middle of throw (aka front wheels as straight as you can with all the trims centered). That is your centered position.
Then set your trim to where the wheels are as straight as you can and the truck tracks straight. Then set the end points and your set!

Great thank you very much
