Two frame rates are available: F and N.

F = Fast (11ms)

N = Normal (16.5ms)

While most servos are compatible with the fast frame rate, some older analog servos require

the use of the slower normal frame rate.

Accessing the Frame Rate Function

1. Press the

SCROLL and CHANNEL keys at the same time and hold.

2. Turn on the transmitter power switch to enter the System Mode.
3. Press the

SCROLL key until FRM appears on the screen.

4. Press the

INCREASE or DECREASE key to select the desired frame rate (N or F).

5. Press the

SCROLL key to access the Auxiliary Channel 3 function.

6. To exit the System Mode, either turn the transmitter power switch off or press the

SCROLL and CHANNEL keys at the same time.

The Auxiliary Channel 3 function of the DX3.0 allows you to select from two 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.

= 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 RC racing

boats and is accessible through the Grip Lever A. In this function, the maximum travel of the

servo is determined by the Endpoint Adjust function, page 24. The servo neutral position can

be altered proportionately via the Grip Lever A for fuel mixture adjustment. When activated,

fuel mixture trim values are visible for the Direct Trim function, page 28.

= 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 Lever A if Grip Button

C is occupied by another function. The left and right travel values are determined by the

Endpoint Adjustment function, page 24.
