The Four Wheel Steering Mixing function allows you to use Auxiliary Channel 3 as a second steering channel, allowing you to
use two separate steering servos for Front and Rear steering. The Four Wheel Steering Mixing function allows you to control either
the Front or Rear steering independently, or Mix the Front and Rear steering so that they can be used together. For example, if
your Rock Crawler uses Four Wheel Steering, you can use the Programming Keys to switch between Front or Rear Independent
Steering, Parallel Four Wheel Steering, and Tandem Four Wheel Steering. In addition, you also have the option of mirroring the
Channel 1 Steering Dual Rate, Exponential, and Servo Speed settings onto the Auxiliary Channel 3 Steering servo. This allows
for an optimum setup since Steering Dual Rate, Exponential, and Servo Speed settings will be the same for both servos.
