ESC Warning LEDs:

•

If the Battery low voltage cutoff (LVC) is reached the

Red LED will blink.

•

The Red LED will automatically turn off should the

battery voltage recover above the Low Voltage

Cutoff chosen.

•

If the ESC has detected a thermal overload the Yellow LED

will blink. Let the ESC to cool down.

Setup / Calibration to Transmitter

To perform the setup/calibration between the ESC and

Transmitter follow these steps:

Turn on the transmitter.

While turning on the vehicle Press and Hold the

setup button, notice the Yellow LED is now ON

solid. When the Yellow LED is on solid you can

release the setup button.

Using the throttle trigger pull Full Throttle until the

Green LED is ON solid.

Next push the throttle trigger to Full Brake until the

Red LED is ON solid.

Now return the throttle trigger to the Neutral position

and the Blue LED is ON solid.

Turn off the vehicle/ESC power switch.

Turn the vehicle/ESC back ON; you are now ready to

use the ESC.

Normal Operation:

•

After turning on the vehicle, the Blue LED will be on for

normal operation.

•

If reverse is active then you will notice the Yellow LED

is also on.

Confirmation of Full Throttle and Brake:

•

While the ESC is on and operational if you pull the throttle

trigger to Full Throttle the Green LED will turn ON Solid.

•

Push the throttle trigger to Full Brake, the red LED will turn

ON solid.

Note: If the brake endpoint adjustment is reduced

after calibration then the Red LED will not turn on.

ESC – reverse operation

Should you get into a situation that requires reverse, after you

have applied any brakes you may have needed, return the

throttle trigger to the neutral position. Wait a moment or two

and then push the trigger forward for reverse.

Note: There is automatic protection within the

Xcelorin ESC. Only after you have stopped and

returned the trigger to neutral will reverse become

available. If you are in reverse you will notice a

delay if while travelling in reverse you pull the trigger

to go forward. This is to help prevent serious damage

to the drivetrain.

Please note the following precautions before running

your Speed-T.

•

The Electronics in this vehicle are not waterproof and you

must avoid running the vehicle in or through standing

water, wet grass, mud or snow.

•

This vehicle is very fast:

o Do not run the vehicle at dusk or in the dark of night.

o Do not run the vehicle if it will be out of sight for any

amount of time.

o Do not drive your vehicle near a crowd of people.

•

Perform a check of the vehicle before going out to run it.

o Ensure the tires are not coming off the rims.

o Generally check the vehicle for items such as a

loose wheel nut, or anything loose on the steering

assembly. The vibrations of running at high speeds

tend to loosen screws and nuts.

•

The Speed-T’s gearing choice from the factory IS NOT

meant for running the vehicle Off-Road and especially not

in grass.

•

Be careful driving when the battery is nearly discharged or

the car is running slowly. You could lose enough power for

the receiver to shutdown and you may lose control.

•

When driving the Speed-T be cautious and use common

sense. The speed of this RC vehicle may surprise

bystanders who could be injured if you accidently hit

them.

•

If your vehicle gets caught or stuck do not pull the throttle

in either forward or reverse. This will overload the ESC and/

or motor resulting in damage to one or possibly both and

is not covered by your warranty.

•

After running a battery pack, allow the electronics several

minutes to cool, before running the next battery pack.

•

When you are running and the batteries are low on

charge the ESC reduces the power to the motor. When this

happens the batteries are very discharged and continued

running may possibly damage your battery. If you are

using LiPo batteries when power to the motor is reduced

immediately stop running the vehicle. Over discharging of

LiPo batteries can be dangerous.

Run time consideration for the Speed-T vehicle.

The single largest factor in run time is the capacity mAh of your

battery pack. The larger the mAh rating the more run time you

will experience.
For example: if you have a 4600mAh battery pack you can

expect close to twice the run time of a 2000mAh battery pack.
The condition of a battery pack is also an important factor in

both run time and speed. As batteries see more use they will

degrade in performance and capacity.

How you drive your Speed-T will also affect your run times. If

you are performing runs, going from a standstill to full speed

repeatedly, you are asking a lot from your batteries. Hard

acceleration draws a lot of current from any battery and will

lead to shortened run time.

Note: Higher mAh rated battery packs will provide

power longer during heavy acceleration and long full

throttle runs.

If the bearings are dirty they will cause significant drag causing

reduced run times and speed.
To improve run times consider the following:

•

Keep your vehicle clean and maintained.

•

Allow more airflow to the heat sink of the Xcelorin ESC.

•

Change the gearing to a lower ratio, this will make the

electronics run cooler. This can be accomplished by using

a smaller pinion gear, or a larger spur gear than those

originally supplied. (The Speed-T comes with a 20-tooth

pinion and an 88-tooth spur gear.)

•

Change to battery packs of higher mAh rating.

•

Is the charger your using the best at charging your

batteries? Check with your local hobby dealer.
