PROFILE SELECTION
The ECM-2.5 electronic control module is factory set to Trail Mode (100%
forward, brakes, and reverse; added brake drag when the throttle trigger
is at neutral).
To activate full power without the additional brake drag
(Sport Mode) or set immediate reverse (Crawl Mode), follow these
steps. The profiles are selected by entering the programming mode
.
Profile Description
Profile #1 (Sport Mode): 100% Forward, 100% Brakes, 100% Reverse
Profile #2 (Trail Mode): 100% Forward, 100% Brakes, 100% Reverse,
Drag Brake at Neutral
Profile #3 (Crawl Mode): 100% Forward, Hill Hold Brakes at Neutral,
Immediate Reverse
Selecting Sport Mode
(Profile #1: 100% Forward, 100% Brakes,
100% Reverse)
1. Connect a fully charged battery to the
ECM-2.5 and turn on your transmitter. The
LED will glow solid green.
2. Press and hold the EZ-Set® button until
the LED begins blinking red (indicating
the Profile numbers).
3. When the LED blinks red once, release the
EZ-Set button.
4. The LED will then turn solid green. The
model is ready to drive.
Selecting Trail Mode
(Profile #2: 100% Forward, 100% Brakes,
100% Reverse, Drag Brake at Neutral)
1. Connect a fully charged battery to the
ECM-2.5 and turn on your transmitter. The
LED will glow solid green.
2. Press and hold the EZ-Set® button until
the LED begins blinking red (indicating
the Profile numbers).
3. When the LED blinks red twice, release
the EZ-Set button.
4. The LED will then turn solid green. The
model is ready to drive.
Selecting Crawl Mode
(Profile #3:
100% Forward, Hill Hold Brakes at
Neutral, Immediate Reverse
)
1. Connect a fully charged battery to the
ECM-2.5 and turn on your transmitter. The
LED will glow solid green.
2. Press and hold the EZ-Set® button until
the LED begins blinking red (indicating
the Profile numbers).
3. When the LED blinks red three times,
release the EZ-Set button.
4. The LED will then turn solid green. The
model is ready to drive.
Note:
If you missed the mode you wanted, keep the EZ-Set button
pressed down and the blink cycle will repeat until the button is
released and a mode is selected.
LOW VOLTAGE DETECTION
The ECM is equipped with three-stage Low Voltage Detection
(LVD) that alerts the driver when LiPo batteries have reached
their minimum voltage (discharge) threshold. Stop immediately
to prevent the battery pack from being discharged below its safe
minimum threshold. Unplug the battery and recharge. Leaving
the battery connected to the vehicle when not is use can cause
permanent battery damage.
Always unplug the battery after use.
