Help with 3 channel contol
 

I purchased a complete rock bull 2 kit (complete with radio, speed control, beadlocks etc.) The radio is a HItec 3 channel aggressor. The problem that I see is that the button for the rear steer is has no way of certering itself. For example: when the button is pushed it pushes the servo all the way to the left when the button is pushed for a second time, the servo is moved all the way to the right.
Question:
How can I get the rear steer to function so that I can control the steering correctly?
Or
How can I get it to center itself after it has been used?

How do other radios work with rear steer. ( I do want a radio with a wheel)

Thank you for your help

You need to replace the switch - go to The Shack or order one online that is a MOMENTARY On-Off-On switch -
