The Auxiliary Channel 3 function of the DX3.0 allows you to select from 2 different types of
Channel 3 servo travel movements, or to inhibit the Auxiliary Channel 3 function. Use the
information below to select the correct Auxiliary Channel 3 function type for your particular
installation. It is suggested the O function (factory preset) be selected for most applications.
LN = The LN, or linear, servo travel function is designed to be used when an engine fuel
mixture servo is required. This function is most commonly used with gas-powered R/C
racing boats and is accessible through the Grip Dial A. In this function, the maximum travel
of the servo is determined by the End-Point Adjust function, page 23. The servo neutral
position can be altered proportionately via the Grip Dial A for fuel mixture adjustment. When
activated, fuel mixture trim values are visible for the Direct Trim function, page 27.
2P = The 2P, or 2 position, Servo Travel function is designed to be used as a transmission
gear shift channel. This feature is designed for use only with vehicles such as the Traxxas
®
T-Maxx. This function is accessible through the Grip Button C or Grip Dial A if Grip Button
C is occupied by another function. In this function, the servo’s travel can be selected to only
three positions: left, center and right. The left and right travel values are determined by the
End-Point Adjustment function, page 23.
0 = The 0 or Inhibit function allows the Brake End-Point Adjustment function, page 31, to be
used. This function is designed to be used with most types of electric and gas-powered RC
cars. This feature is extremely popular, as it allows the amount of panic braking accessible
through the throttle trigger’s braking position to be adjusted during operation for maximum
effectiveness. When activated, the braking valves will be visible via the Direct Trim function,
page 27.
