TENACITY SCT RTR, AVC: 1:10 4WD SCT • INSTRUCTION MANUAL
DESCRIPTIONS
1. Running
Mode
-
Forward Only with Brake
Intended for competition use, this mode allows only forward and brake controls.
-
Forward/Reverse with Brake
This mode is the basic all-around mode, allowing forward, reverse and brake controls.
To engage reverse while moving forward, apply the brake until the vehicle has come to
a complete stop, release brake, then apply the brake again. While braking or in reverse,
engaging the throttle will result in the vehicle immediately accelerating forward.
2. Drag Brake Force
Adjusts the amount of brake automatically applied when the throttle is returned to the
neutral position. This simulates the engine braking effect of a full-scale vehicle, allowing
improved turn-in and your vehicle’s general response to controls.
3. Low
Voltage
Cutoff
This function helps to prevent battery over-discharge. The ESC continuously monitors the
battery’s voltage. If the voltage falls below the voltage threshold for 2 seconds, the output
power shuts off and the red LED fl ashes twice repeatedly.
The cutoff threshold calculation is based on individual Li-Po cell voltage. For Ni-MH batteries,
if the voltage battery pack is higher than 9.0V, it will be treated as a 3-cell Li-Po battery
pack; if it is lower than 9.0V, it will be treated as a 2-cell Li-Po battery pack. Example: for a
8.0V Ni-MH battery pack used with a 2.6V/cell threshold, it will be treated as a 2-cell Li-Po
battery pack and the low-voltage cut-off threshold will be 5.2V (2.6x2=5.2).
4. Start Mode (Punch)
Sets the initial throttle punch when the car accelerates. Level 1 gives
a very soft initial acceleration and level 4 gives a stronger initial acceleration.
5. Max Brake Force
Adjusts the maximum braking force. A higher value provides stronger braking,
but can also cause the wheels to lock, resulting in loss of control of the car.
6. Max Reverse Force
This parameter adjusts the maximum power when travelling in reverse.
7. Initial Brake Force (minimum brake)
Adjusts the minimum amount of braking power when the brakes engage. The default value
is equal to the drag brake value. A high value can lock the wheels when the brake is used.
8. Neutral
Range
Adjusts the throttle sensitivity around the neutral point. A higher value results in the
throttle having to be moved more for the vehicle to move forward, backward or brake.
9. Timing
Adjusts the motor drive current timing. More timing gives more performance, but can
lower effi ciency and cause damage to the motor and/or ESC by overload or overheating.
NOTICE:
Always ensure the motor timing is set correctly. Failure to set the motor
timing correctly can result in damage to the motor and ESC. Refer to the manufacturer
instructions for recommended timing settings.
The Following Programmable Items require the optional Digital ESC Program Box:
10. and 11.
Available Items are subject to fi rmware updates to the ESC and the optional
digital program box.
12. Motor Rotation
Allows you to make this change in the ESC so no wires need to be changed between the
ESC and the motor.
13. Li-Po Cells
Allows the ESC to automatically detect or manually set the number of cells in your Li-Po
battery back.

ESC FUNCTIONS AND MODES
The ESC includes programming options so you can adjust the way your vehicle performs.
Refer to the included settings table to adjust the ESC for your driving conditions.
ESC PROGRAMMING PROCEDURE
Programming is accomplished using the SET button on the ON/OFF switch or Digital Program
Box (DYN3748).
1. Connect a fully charged battery to the ESC.
2. Power ON the ESC using the ESC switch.
3. Hold the SET button for 1 second until the green LED blinks, then release the SET button
to enter programming mode.
4. Press and release the SET button as needed to get to the desired menu option (the Green LED
will blink corresponding to the menu item number). Programming menu items 1 through 9 are
accessible using the SET button on the ESC. Programming menu items 10 and above are only
accessible using the optional ESC programming card. Programming of menu items 10 and 11
is only possible after fi rmware updates to the ESC programming card.
5. When at the desired menu item, hold the SET button for 3 seconds until the red LED blinks.
6. Press the SET button to move among the settings based on how many times the red LED
blinks (Refer to the table for more information).
7. Save the setting by holding the SET button for 3 seconds.
8. Power OFF the ESC switch and repeat the instructions above to change other settings.
Tip:
If desired, the ESC programming can be returned to default settings
by powering ON the ESC and holding the SET button for 5 seconds.
