You can skip to page 14 if this is not your first time running the vehicle.

ESC Setup

There are two battery modes to choose from (NiMH or LiPo).
Factory setting is set to NiMH mode.

Lipo Battery Mode
If the power is cutting off and on (pulsing) while driving, the LiPo battery cutoff has been activated in the speed control. Stop driving the car immediately and recharge or replace the battery.
Choose Battery Mode
The ESC is programmed with the use of jumpers to select setting. (Tweezers are recommended to plug in the jumpers)

Low voltage cut-off protection
If the voltage of the battery pack is lower than the threshold for 2 seconds, the ESC will enter the protection mode.
When the car stops, the red LED blanks on the ESC to indicate that the low voltage cut-off protection has been activated.

5-9 cells
NiMH| Output reduces to 50% at 4.5V. ESC cuts off at 4.0V when battery cannot supply enough voltage.
---|---
2S LiPo| Output reduces to 50% at 6.5V. ESC cuts off at 6.0V when battery cannot supply enough voltage.
3S LiPo| Output reduces to 50% at 9.75V. ESC cuts off at 9.0V when battery cannot supply enough voltage.

Checking Fail Safe Operation

This car has a built-in fail safe system. If the radio glitches, because of interference or the car goes out of range, it will go into neutral to protect your car.
The fail safe system has been setup at the factory, but you should become familiar with the function of the fail safe and check the operation before running.

2

LED light will flash and vehicle will not move.This means that the fail safe is working properly.

Cautions
Reference Section Abschnitt
If the red LED is flashing, but the throttle servo is not applying the brake, refer to page 32 and perform the fail-safe setup procedure .

2-3 Radio Control Car Operating Procedures
1 Turn on Switch

2 Checking Radio Range

To properly check the range, have a friend hold the truck and walk to the farthest distance that you plan to operate your model. Operate the controls to make sure the model responds correctly. Do not operate the model if there are any problems with the radio system. If you switch on the R/C car first before the transmitter, you may lose control of the R/C car.

Caution
2.4GHz radio frequency only functions by line of sight. If you drive behind a solid object or around a corner and lose sight of the vehicle, you may lose control of the RC model.

5 Practice Turnin

Install body and enjoy!
Allow the car to cool down for 15 minutes between each run.
When the car is running toward the driver, the directions of the steering wheel are reversed.
Once you become comfortable driving your RC car, practice driving on a track with pylons.

Cautions

Do not run in water or sand.
Do not run on public streets or highways. This could cause serious accidents, personal injuries, and/or property damage.
6 Turning R/C Unit Off
Attention
Turn off receiver first, then turn off transmitter.
If you switch off the transmitter fist before the R/C car, you may lose control of the R/C car.

Cautions
Make sure receiver is turned OFF before connecting the battery, the vehicle may run out of control.

Attention

Driving in Wet Conditions
This HPI vehicle is designed to provide water protection for the on-board radio system components so it can be driven in wet conditions.
The vehicle is not designed to be completely submerged in water. Driving in wet conditions will require additional vehicle maintenance.
Notes:
Never drive the vehicle in stormy conditions where lightning could be present. The transmitter is not waterproof; always keep it protected from rain and water. Remove all water/mud and dry the vehicle completely after driving. Check the  vehicle for trapped water in the tires, transmission, etc. Some metal parts like bearings and hinge pins will need lubrication after driving in wet conditions. The electric motor is not designed to be submerged in water. If water gets inside, it can reduce the life of the motor. Most LiPo battery packs are not designed to operate in wet conditions. Consult the instruction manual or manufacturer for limitations. Inspect the inside of the waterproof radio enclosure after
driving in wet conditions. Adjust wiring and seals as needed to prevent water damage. After running in water, dry off any water from ESC and connectors.

Receiver Connections

Overheat Protection

When the internal temperature of the ESC is higher than a factory preset threshold for 5 seconds, the ESC will reduce and will cut off the output power.
Once the Overheat Protection is activated, the throttle repeats turning on and off quickly and acceleration becomes erratic. Stop driving immediately and solve the problem by referring to the Troubleshooting guide. Do not drive the R/C car until the LED turns off. Allow the Speed Controller to cool down for 15 minutes.
The Overheat Protection function will turn off and you can drive the R/C car again.
Throttle Signal loss Protection

The ESC will cut off the output power if the throttle signal has been lost for 0.1 second.
The “Fail Safe“ function of the radio system is strongly recommended to be activated.

Binding and Fail Safe

Programming a receiver to recognize the code of only one specific transmitter. Binding and fail-safe is pre-set from the factory.
Caution
If you change transmitters or add a receiver, you must re-bind before operating your vehicle.

1. In France, choose France mode. Otherwise, choose normal mode.
   

2. Place the transmitter and the receiver close to each other (within one meter).
   Turn the power switch on the transmitter to the ON position.

3. Press and hold the receiver setup button, then turn the power switch to the ON position. The receiver LED will flash quickly. Release the setup button after 1 second.
   

4. Press and hold the binding button on the transmitter for 1 second until the LED on the receiver is continuously lit.
   

Fail Safe Setup
Refer to page 34 for fail safe setup.
Cautions
Any new binding of transmitter & receiver will clear the preset fail safe.
To confirm that fail safe is working properly, the ESC will go in to the neutral position and the vehicle will not move when you shut off the transmitter.
See page 14 and check the Fail Safe function to see if it is working properly.You do not need to repeat this procedure each time you run.
End Point Adjustment / EPA
End point adjustments allow you to set the limits of steering and throttle.
Caution
Do not adjust the servo beyond its limit. Damage may occur.

1. Turn the power switch to the “ON” position on the transmitter.
   Turn on the receiver. Place the car on a stand and adjust steering and throttle trim, then turn dual rate to maximum setting.
   

2. Turn steering wheel all the way to the left and adjust your end point to the desired angle.
   Damage to your servo may occur if your maximum steering endpoints are set too far.
   

3. Turn steering wheel all the way to the right and adjust your end point to the desired angle.
   Damage to your servo may occur if your maximum steering endpoints are set too far.
   

4. Turn the dial to its maximum level.
