IMPORTANT – READ THIS BEFORE RUNNING
PLEASE READ ALL INSTRUCTIONS AND FAMILIARIZE YOURSELF WITH THE PRODUCTS AND CONTROL BEFORE OPERATION.
This product is not a toy. It is a high performance model product. It is important to familiarize yourself with the model, its anual, and its construction before assembly and operation. Adult supervision is necessary

CAUTION
To avoid serious personal injury and property damage, operate all remotely controlled models in a responsive manner as outlined below. R/C car models can exceed speeds of 40km/h (25mph), and cannot be stopped quickly.

1.  Never run R/C models on the street or highways, as it could cause or contribute to serious traffic accidents.
2.  Never run an R/C model near people or animals, nor use people or animals as obstacles when operation R/C vehicles.
3. To avoid injury to persons or animals, and damage to property, never run a R/C model in a confined or crowed area.
4.  Running R/C models into furniture or other inanimate objects will cause damage to the objects and the R/C models.

CAUTION DURING OPERATIONS

When the R/C model is in operation, dot not touch any of its moving parts, such as drive shafts, wheels, as the rotating parts can cause serious injury.

1.  The vehicle motor gets very hot during running and could cause burns if touched.
2. Make sure that no one else is using the same frequency as yours in your running area. Using the same frequency at the same time, whether is driving, flying or sailing, can cause loss of control of the R/C models, resulting in serious accidents.
3. Properly connect plugs. To prevent electrical shock and/or damage to the product resulting from a short-circuit; insulate connections with heat shrink tubing or electrical tape. Before running vehicle, check that battery wiring and plugs are not so loose as to drag on the ground. Properly secure cables using electrical tape or nylon tie-wraps.
4. Stiff rotation of gears, shafts, joints and wheels can burn out the motor. It’s recommended to check proper joint and shaft rotation by using one 1,5V dry cell during assembly of the model.
   A worn motor will overheat and result in a short running time. Replace a worn out motor as soon as possible.
5. R/C models will run out of control when either the receiver or transmitter battery voltage drops off. Stop the vehicle immediately when the car starts to show down to prevent it from running out of control.

SAFETY PRECAUTIONS

Follow the outlined rules for safe radio control operation.
Avoid running the car in crowed area and near small children.
Make sure that no one else is using the same frequency in your running area. Using the same frequency at the same time can cause serious accidents, whether it’s driving, flying or sailing.
Avoid running in standing water and rain. If R/C unit, motor, or battery get wet, clean and dry throughly in a dry shaded area. R/C operating procedures

1. Make sure the transmitter controls and trims are in neutral. Switch on transmitter.
2. Switch on receiver.
3. Inspect operation using transmitter before running.
4. Adjust steering servo and trim so that the model runs straight with transmitter in neutral.
5. Reverse sequence to shut down after running.
6. Make sure to disconnect/remove all batteries.
7. Completely remove sand, mud, dirt etc
8. Store the car and batteries separately when not in use

SETTING UP THE MODEL

To greatly enhance the overall performance of your car, it’s necessary to tune the vehicle to the track (and its surface conditions) on which you will be racing. Make adjustments referring to the instruction manual, keeping in mind that “balance” is the key word.

1. Tires
   Tires have a great influence on the performance of your car, and are normally the first components tuned. Select the right tires for the track you are racing on.
2. Toe-in and Toe-out
   Adjusting the car toe-in a little, by pointing the wheel inwards, provides the car with good straight running and moderate  steering characteristics. Toe-out, which point the wheels outwards, gives sharp and crisp steering. Take care not to overdo.
3. Camber angle
   While taking the corners, the car is forced to go outwards, causing instability. The area of contact on each tire is determined by the camber angle, and therefore the traction of the tires can be made greater or lesser by adjustment of camber angle. To increase traction during cornering, adjust camber angle negative, and reduce  traction, adjust for positive camber.
4. Ground clearance and suspension drop
   Ground clearance and/or rebound stroke has a great effect on stability during cornering, acceleration, and braking. Ground clearance can be adjusted by altering damper spring tension and stiffness.
5. Gear ratio
   Proper gear ratio should be determined by the available output power of the motor; type of battery; track condition and layout It should be also noted that running the car on a good grip surface suggests use of pinion gear 1 teeth smaller, in order to effectively use all of the available battery power.

Tools Required not included in the kit

CHASSIS

For obvious reasons of security, the KONECT KT3X radio system is equipped with an automatic power shut down of the receiver when the user turns the transmitter
On while turning the steering wheel or touching the throttle trigger.
Consequently on ignition, the vehicle won’t (for example) unintentionally accelerate. The transmitter Led flashes red & green, and the user cannot use it anymore. Then it must be turned Off and On without touching anything else.

KR3X receiver
BAT : Battery connection
CH3 : Third channel
CH2 : Second channel
CH1 : First channel

Battery Installation

Battery LED Indicator

• During normal operation, the transmitter LED should be solid green ON, and the receiver LED should be red ON (transmitter & receiver paired).
  Warning: Never disassemble batteries or put the batteries in fire, chemical agents, otherwise they may cause personal injuries or property damages.
  Battery Disposal: Observe corresponding regulations about wasted battery treatment regulations.
  Submit the wasted batteries to specific recycling stations.

1. Pairing your radio
   Pairing your receiver to your KT3X
   1. Transmitter turned off, power the receiver On. The receiver LED flashes Red
   2. Press and Hold the «BIND/EPA» transmitter button while powering On the transmitter.
   The receiver LED becomes solid Red, and the transmitter solid green: your receiver is paired with your transmitter. You can release the «BIND/EPA» button.
2. Inversion
   Reversing is used to change the response direction of steering wheel and throttle trigger.
   Steering Reverse: Reverse the response direction when operating steering wheel.
   Turning left steering wheel, the model turns right while turning right the model turns left.
   Throttle Reverse: Reverse the response direction when operating throttle trigger.
   Pushing forward throttle trigger the model moves backward while pulling back, the model moves forward.
3. Neutral settings (Trim)
   KT3X features trimming steering.
   Steering Trim Dial: Adjust the neutral position of steering servo when the wheels are straight ahead.
4. Steering End Point Adjustment
   Steering Dual Rate enables to adjust the same maximum steering angle of servo on both sides (Left and Right) when model makes steering. The Steering Dual Rate affects the sensitivity of servo. Rotate clockwise = increase maximum steering angle; rotate counterclockwise = reduce maximum steering angle.
   The minimum adjustment of Dual Rate (counterclockwise to the max) makes a zero steering angle.
5. Power adjustment
   The power of the throttle can be adjusted using the “SPEED” potentiometer. The further the cursor is turned clockwise, the faster the car will go. It is therefore possible, thanks to this slider, to take advantage of a power range of the car from 0% to 100%.

B) Hold the “SET” key and then switch on the ESC, and release the “SET” key as soon as possible when the red LED begins to flash. (Note 4)

BEGIN TO USE THE NEW ESC

WARNING! THIS BRUSHLESS SYSTEM IS VERY POWERFUL! FOR SAFETY, PLEASE ALWAYS KEEP THE WHEELS AWAY FROM THE TRACK WHEN YOU BEGIN TO SWITCH ON THE ESC. 

1. Connect the ESC, motor, receiver, battery and servo according to the following diagram
   The #A, #B, #C wires of the ESC can be connected with the motor wires freely (without any order). If the motor runs in the opposite direction, please swap any two wire connections.
2. Throttle Range Setting (Throttle Range Calibration) In order to make the ESC fit the throttle range, you must calibrate it when you begin to use a new ESC, or a new transmitter, or change the settings of neutral position of the throttle stick, ATV or EPA parameters, etc. Otherwise the ESC cannot work properly.
   There are 3 points need to be set, they are the top point of “forward”,” backward” and the neutral point.
   The following pictures show how to set the throttle range with a Futaba TM transmitter.

Note4: If you don’t release the “SET” key after the red LED begins to flash, the ESC will enter the program mode, in such a case, please switch off the ESC and re-calibrate the throttle range again from step A.

C) Set the 3 points according to the steps shown as the pictures on the right side.

1. The neutral point
   Move the throttle stick at the neutral point, and then click the SET key, the green LED flashes 1 time.
2. The end point of forward direction
   Move the throttle stick at the end point of forward direction, and then click the SET key, the green LED flashes 2 times.
3. The end point of backward direction 
   Move the throttle stick at the end point of backward direction, and then click the SET key, the green LED flashes 3 times.

D) Throttle range is calibrated; motor can be started after 3 seconds.

Check the LED Status in Normal Running

1. Normally, if the throttle stick is in the neutral range, neither the red LED nor the green LED lights.
2. The red LED lights when the car is running forward or backward.
3. The green LED lights when the throttle stick is moved to the top point (end point) of the forward zone.

ALERT TONES

1. Input voltage abnormal alert tone: The ESC begins to check the input voltage when power on, if the voltage is out of the normal range, such an alert tone will be emitted: “beep-beep-, beep-beep-, beep-beep-” (There is 1 second interval between every “beep-beep-” tone).
2. Throttle signal abnormal alert tone: When the ESC can’t detect the normal throttle signal, such an alert tone will be emitted: “beep-, beep-, beep-” (There is 2 seconds interval between every “beep-” tone).

PROTECTION FUNCTION

1. Low voltage cut-off protection: if the voltage of a LiPo battery pack is lower than the threshold for 2 seconds, the ESC will cut off the output power. Please note that the ESC cannot be restarted if the voltage of each LiPo cell is lower than 3,5V.
   For NiMH battery packs, if the voltage of the whole NiMH battery pack is higher than 9.0V but lower than 12V, it will be considered as a 3S LiPo; if it is lower than 9.0V, it will be considered as a 2S LiPo. For example, if the NiMH battery pack is 8.OV, and the threshold is set to 2,6V/cell, it is considered as a 2S LiPo, and the low-voltage cut-off threshold for this NiMH battery pack is 2.6 x 2 = 5.2V.
2. Over-heat protection: when the temperature of the ESC is over a factory preset threshold for 5 seconds, the ESC will cut off the output power. You can disable the over-heat protection function for competition race.
3. Throttle signal loss protection: the ESC will cut off the output power if the throttle signal is lost for 0.2 second.

TROUBLE SHOOTING

PROGRAM THE ESC

1. Program Method
   Note5:
   • In the program process, the motor will emit “Beep” tone at the same time when the LED is flashing.
   • If the “N” is bigger than the number “5”, we use a long time flash and long “Beep—” tone to represent “5”, so it is easy to identify the items of the big number.
   For example, if the LED flashes as the following:
   “A long time flash + a short time flash” (Motor sounds “Beep—Beep”) = the No. 6 item
   “A long time flash + 2 short time flash” (Motor sounds “Beep—BeepBeep”) = the No. 7 item
   “A long time flash + 3 short time flash” (Motor sounds “Beep—BeepBeepBeep”) = the No. 8 item …… And so on.
   Programmable Items List (Italic texts in the above form are the default settings)

   Programmable Items	Programmable Value
   	1	2	3	4	5	6	7	8	9
   Basic Items
   1. Running Mode	Forward Only with Brake	Forward/Reverse with Brake
   2. Drag Brake Force	0%	5%	10%	20%	40%	60%	80%	100%
   3. Low Voltage Cut-Off Threshold	Non-Protection	2.6V/Cell	2.8V/Cell	3.0V /Cell	3.2V /Cell	3.4V /Dell
   4. Start Mode (Punch)	Level 1	Level 2	Level 3 75%	Level 4
   5. Max Brake Force	25%	50%		100%

2. Programmable Values
   2.1. Running Mode: With “Forward Only with Brake” mode, the car can go forward and brake, but cannot go backward, this mode is suitable for competition; “Forward/Reverse with Brake” mode provides backward function, which is suitable for daily training.
   Note: “Forward/Reverse with Brake” mode uses “Double-click” method to make the car go backward. When you move the throttle stick from forward zone to backward zone for the first time (The 1st “click”), the ESC begins to brake the motor, the motor speeds down but it is still running, not completely stopped, so the backward action is NOT happened immediately. When the throttle stick is moved to the backward zone again (The 2nd “click”), if the motor speed is slowed down to zero (i.e. stopped), the backward action will happen. The “Double-Click” method can prevent mistakenly reversing action when the brake function is frequently used in steering.
   2.2. Drag Brake Force: Set the amount of drag brake applied at neutral throttle to simulate the slight braking effect of a neutral brushed motor while coasting.
   2.3. Low Voltage Cut-Off: The function prevents the lithium battery pack from over discharging. The ESC detects the battery’s voltage at any time, if the voltage is lower than the threshold for 2 seconds, the output power will be cut off, and the red
   LED flashes in such a way: “❏-❏-, ❏-❏-, ❏-❏-”.
   There are 6 preset options for this item. You can customize the cutoff threshold by using a LCD program box (optional equipment) to trim it with a step of 0.1V, so it will be more suitable for all kinds of batteries (NiMH, NiCd, Li-ion, Lipo, LFP,etc). Please always keep in mind that the customized value is not for each cell, it is for the WHOLE battery pack.
   2.4. Start Mode (Also called “Punch”): Select from “Level1” to “Level4” as your like, Level1 has a very soft start effect, while level4 has a very aggressive start effect. From Level1 to Level4, the start force is increasing.
   2.5. Maximum Brake Force: The ESC provides proportional brake function. The brake force is related to the position of the throttle stick. Maximum brake force refers to the force when the throttle stick is located at the top point of the backward zone.
   A very large brake force can shorten the brake time, but it may damage the gears.
3. Reset All Items To Default Values
   At any time when the throttle is located in neutral zone (except in the throttle calibration or parameters program process), hold the “SET” key for over 3 seconds, the red LED and green LED will flash at the same time , which means each programmable item has be reset to its default value.

OPTIONAL ACCESSORIES

1. Cooling fan (12V)
   The high voltage fan is necessary when you use 3S LiPo or Ni-MH battery more than 6 cells.
   WARNING! Please note the original cooling fan (5V) is only recommended to work with 2S LiPo or 4-6 cells Ni-MH battery. Please DON’T use it with a 3S LiPo or Ni-MH battery more than 6 cells.
   Please check the label of the cooling fan carefully to confirm its working voltage before using it.
2. LED Program Card
   Program card is an optional equipment which needs to be purchased separately. It has a friendly user interface. The process of programming the ESC becomes quite easy and fast with this pocket sized device. When the programmable value needs to be changed, please just plug the control wires of the ESC (trio wires with black, red and white color) into the socket of the program card (The socket is on the right corner, and marked with ), and then connect the main battery pack to the ESC. After several seconds, each item’s value will be shown on the program card. Use “ITEM” and “VALUE” buttons to select the programmable items and new values, and then press “OK” button to store the new settings into the ESC.
   

• The program port is multiplexed with the cooling fan port, please disconnect the cooling fan, and then use program cable to connect the fan port of the ESC to the LED program card.
