The electronic speed control is factory set and should not require any adjustments. These instructions are provided for your reference.

Transmitter Adjustments for the electronic speed control

Before attempting to program your ESC, it is important to make sure your TQ transmitter is properly adjusted (set back to the factory defaults). Otherwise, you may not get the best performance from your speed control.

The transmitter should be adjusted as follows:

1.Set the throttle neutral switch to the 50/50 setting. This adjusts the transmitter’s throttle trigger throw to 50% for throttle and 50% for braking and reverse.

2.Set the throttle trim control to the middle “0” setting.

3.Set the Channel 2 servo reversing switch to the left position. Do not change the position of any of the servo reversing switches after programming the ESC.

4.You are now ready to program your speed control.

Setup Programming (Calibrating your ESC and transmitter)

Read through all of the following programming steps before you begin. If you get lost during programming or receive unexpected results, simply unplug the battery, wait a few seconds, plug the battery back in, and start over.

1.Disconnect each of the motor wires between the ESC and the motor. This is a precaution to prevent runaway when the speed control is turned on before it is programmed.

7. When the LED turns solid GREEN, programming is	D
complete. The LED will continuously shine green
indicating the ESC is on and at neutral (D).
ESC Operation	Solid Green

To operate the speed control and test the programming, place the vehicle on a stable block or stand so all of the driven wheels are off the ground. Reconnect the motor wires. Always make sure that objects and fingers are clear of the wheels.

1.With the transmitter on, press the EZ-Set button for ½ second, until the LED shines GREEN, then immediately release the button. This turns on the ESC. If you press and release too quickly, you may hear the steering servos jump but the LED may not stay on. (Note: If the throttle is not at neutral or if the throttle trim has been altered, the LED will turn off after one second and the wheels may begin to drive.)

2.Apply forward throttle. The LED will turn off until full throttle power is reached. At full throttle, the led will shine GREEN.

3.Move the trigger forward to apply the brakes. Note that braking control is fully proportional. The LED will turn off until full braking power is reached. At full brakes, the LED will shine GREEN.

4.Return the throttle trigger to neutral. The LED will shine GREEN.

5.Move the throttle trigger forward again to engage reverse (Profile #1). The LED will turn off. Once full reverse power is reached, the LED will shine GREEN.

6.To stop, return the throttle trigger to neutral.

(Note: There is no programmed delay when changing from reverse

2.Turn on the transmitter (with the throttle at neutral).

3.Connect a fully charged battery pack to the ESC.

4.Press and hold the EZ-Set button (A). The LED

will first turn green and then red. Release the EZ-Set button.

to forward. Use caution to avoid slamming the speed control from reverse to forward. On high-traction surfaces, this could result in transmission or driveline damage.

7.To turn the ESC off, press the EZ-Set button until the green LED turns off.

6.When the LED blinks RED TWICE. Push the throttle trigger to the full reverse and hold it there (C).

Thermal Shutdown Protection

The XL-2.5 speed control is equipped with thermal shutdown protection to guard against overheating caused by excessive current flow. If the operating temperature exceeds safe limits, the ESC will automatically shut down and the ESC LED will flash red. The LED on the face of the ESC will continuously flash red, even if the throttle trigger is moved back and forth. After the speed control cools down to a safe level, the LED will continuously shine green. The ESC will once again function normally.
