TRAXXAS TRX-4 • 47
Selecting a Throttle Mode:
SPORT, RACE, TRAINING, TRAIL, OR CRAWL
1. Connect fully charged batteries to the model and turn on your
transmitter.
2. With the model off, press and hold the EZ-Set button until the LED
turns solid green, then solid red, and then begins blinking red. It
will blink once, then twice, then three times, then repeat.
One blink = Sport Mode
is the default setting. It allows full forward
and reverse throttle.
Two blinks = Race Mode
removes reverse throttle in case your
track does not allow it.
Three blinks = Training Mode
will slow the model down by 50%
for young or inexperienced drivers.
Four blinks = Trail Mode
is similar to Sport Mode, but with added
drag brake when the throttle trigger is at neutral. This is the default
setting for the TRX-4 and provides a good balance of smooth
driving and additional drag brake for descending hills.
Five blinks = Crawl Mode
allows 100% brake (hill hold) with
immediate reverse when the throttle is at neutral. This setting is
best suited for technical courses where very precise movements are
required.
3. Release the EZ-Set button after the number of blinks for the mode
you wish to select.
Note:
If you missed the mode you wanted, keep the
EZ-Set button pressed down and the blink cycle will repeat.
4. The LED will blink and then turn solid green (Low-Voltage
Detection ACTIVE) or red (Low-Voltage Detection DISABLED).
The model is now ready to drive in the mode you have selected.
LED Codes and Protection Modes
• Slow Blinking Red:
Low battery voltage. If you see
this code because a NiMH battery was connected to
an ESC with Low- Voltage Detection turned on, then
follow the calibration steps below to release the code
and change the ESC to NiMH mode.
• Fast Blinking Red and Green:
Overvoltage. This
code can appear when a fully charged NiMH battery
is connected to the ESC with Low-Voltage Detection
turned on. Follow the calibration steps below to
release the code and change the ESC to NiMH mode.
• Fast Blinking Red:
Overtemp. Allow the ESC to
cool before continuing. The ESC can get too hot in
situations such as climbing and crawling in high gear,
which increases load on the system. Use low gear for
climbing and crawling.
