Throttle
Deadband
The throttle deadband feature is used to reduce/eliminate the dead throttle area that exists at
neutral to the starting point of throttle and from neutral to the starting point of braking. This
area is sometimes known as deadband. As more throttle trim (also known as static brake)
is applied, more of the dead trigger area right off neutral exists. To eliminate the throttle
deadband, adjust a forward value such that your vehicle’s wheels just start to turn when the
trigger is slightly squeezed. This provides the most accurate feel and eliminates the dead
area in the throttle. To eliminate the braking deadband, adjust the brake value such that
your vehicle starts to slow down when the trigger is slightly pushed. This provides the most
accurate brake feel and eliminates the dead area when braking.
Accessing the Throttle Deadband Function
1. Turn the transmitter power switch on.
2. Press the
SCROLL key to access Function mode.
3. Press the SCROLL key until TDB appears on the screen.
4. Move the trigger accordingly to adjust the forward or braking deadband.
5. Press the
INCREASE or DECREASE key to select the desired value necessary to
eliminate dead area.
6. Press the SCROLL key to access Exponential mode.
7. To exit the Function mode, either turn the transmitter power switch off or press the
SCROLL and CHANNEL keys at the same time.
