Operation Precautions

[Range Test Procedure]

Have a friend hold the model, or place on a stand where the sticks or prop can not come in contact with any object. Operate from a distance of about 100 feet. Be sure to check the movement of each servo to make sure it follows the movement of the steering stick and throttle stick. If the servos do not follow the commands from the transmitter or any type of interference is detected, Do Not operate the model.

(Turning on the power switches)

Always check the throttle stick on the transmitter to be sure it is at the neutral position.

  1. Turn on the transmitter power switch.
  2. Turn on the receiver or speed control power switch.

(Turning off the power switches)

Always be sure the engine is not running or the motor is stopped.

  1. Turn off the receiver or speed control power switch.
  2. Then turn off the transmitter power switch.

If the power switches are turned off in the opposite order the model may unexpectedly run out of control and cause a very dangerous situation.

  1. Make all adjustments to the radio control system with engine not running, or the electric motor disconnected. If the engine is running or the motor is connected while adjustments are made, the model may run out of control.
  2. Remove the main battery source from electric powered models when they are not being used. Should you accidentally leave the receiver switch on, the model could run out of control.

(Fail safe function)

Before running (cruising), check the fail safe function.

Check Method:

Before starting the engine, check the fail safe function as follows:

  1. Turn on the transmitter and receiver power switches.
  2. Turn off the transmitter power switch.
  3. Check if the fail safe function moves the servos to the preset position when reception fails.

The fail safe function is a safety feature that minimizes set damage by moving the servos to a preset position when reception fails. However, if set to a dangerous position, it has the opposite effect.

Setting example: Throttle idle or brake position

Storage and Disposal Safety Precautions

A used Ni-Cd / Ni-MH battery is valuable resource. Insulate the battery terminals and dispose of the battery by taking it to a battery recycling center.

Other Safety Precautions

The electrolyte in Ni-Cd / Ni-MH batteries is a strong alkali. Should you get even the smallest amount of the electrolyte in your eyes, DO NOT RUB. Wash immediately with water and seek medical attention at once. The electrolyte can cause blindness. If electrolyte comes in contact with your skin or clothes, wash with water immediately.

Assembly Precautions

How to link the transmitter and the receiver

Each transmitter has an individually assigned, unique ID code. In order to start operation, the receiver must be linked with the ID code of the transmitter with which it is being paired. Once the link is made, the ID code is stored in the receiver and no further linking is necessary unless the receiver needs to be used with another transmitter. (For T/R set, the link is already done at factory.)

Link procedure

  1. Bring the transmitter and the receiver close to each other, within 0.5 meter.
  2. Turn on the transmitter and the receiver.
  3. Push and hold the Link Switch of the receiver.
  4. When the link is complete, the LED in the receiver changes to solid green.

LED status vs receiver's condition:

No signal reception OFF
Receiving signals On
Receiving signals, but ID is unmatched. Blink
Receiving signals, when F/S is set. It is turns on and a fast blink for the first one second.

WARNING: After the linking is done, please cycle receiver power and check that the receiver to be linked is really under the control of the transmitter. Do not perform the linking procedure with motor's main wire connected as it may result in serious injury.

Fail Safe Function (F/S)

This function moves the throttle servo to a preset position when the receiver cannot receive the signal from the transmitter for some reason. When the signal from the transmitter can be received again, this function automatically resets. The throttle position at the link operation is memorized.

Transmitter Set-Up Procedures

*When making these settings adjustments, do so with the motor disconnected or the engine not running.

Servo Horn Installation Instructions

  1. Connect the receiver, servos, and other components and then turn on the power switches to transmitter and receiver. *Both servos will move to the neutral position.
  2. At this time install the servo horn in the manner described in the instruction manual provided with the model this system will be used in.

Reversing The Servo Operation Direction

Should the servo operate in the opposite direction required for your application, reverse the direction with the servo reversing.

E.S.C. MC231CR / MC331CR

NEUTRAL, HIGH, AND BRAKE MAX POINT SETTINGS

Before setting each point, set the transmitter throttle channel trim to neutral.

* Since the data is read at the end of setting of all points, the points cannot be set independently. If the amp power was turned off during setting, the setting points cannot be memorized. (The previous settings are retained.) The confirmation beep sounds only when the motor was connected.

Steering Trim

Steering neutral adjustments can be made by moving the Steering trim knob to the left or right.

Racers Tip

When you install a servo, always check to be sure the servo is at its neutral position. Adjust the servo horn hole position and linkage so both are parallel. When a servo saver is used, place it as close to center position as possible. Be sure the steering trim on the transmitter is at the neutral position.

Trim Operation And Maximum Travel

Changing the trim can affect the overall settings. When adjustments are made with the trims, recheck your installation for maximum travel. (Steering D/R).

When Trim usage is extreme

If it takes most of your trim movement to get a servo to the neutral position, reposition the servo horn or servo saver on the servo and inspect your linkage installation.

Throttle Trim

Throttle neutral adjustments can be made moving the throttle trim to the left or right.

Racers Tip

When using an electronic speed control, set the throttle trim to neutral and make adjustments to the speed control. On a gas powered model, set the trim to neutral and adjust the linkage to the point where the carburetor is fully closed in accordance with the engine instruction manual.

Trim Operation and Travel

Trim adjustments will affect the overall servo travel. Check the brake side (backward) movement when changes are made.

When trim movement is extreme

If you use most of the trim movement to get the servo to the neutral position, recenter the servo horn closer to the neutral position and inspect your throttle linkage.

Steering Dual Rates

Use this function to adjust the steering travel of your model. If the model understeers (push) while cornering, add steering by turning the D/R button. When the model oversteers (loose), take away steering by turning the D/R button.

WARNING: Be sure that the steering linkage does not bind or come in contact with any suspension parts or arms. If unreasonable force is applied to the servo, the servo may be damaged and result in loss of control.

CAUTION: Adjust the Steering Trim after adjusting the Steering Dual Rate Dial.

Servo Reversing

This function reverses the rotation direction of the servo.

When the trim position deviates from the center, the deviation will be on the opposite side when the servo is reversed.

It operated a steering to the left, but a car turned right. Change the direction of the steering reversing switch.

MC231CR/MC331CR Function

CANCELLING THE REVERSE FUNCTION

The amp reverse function can be cancelled by the following method so that the model can be used even in races that prohibit reverse running. (Brake operation only)

BRAKE/REVERSE OPERATING INSTRUCTIONS

Operation can be switched to reverse operation by returning the throttle stick from the brake position to the neutral position. Then turn down the stick.

PROTECTION CIRCUIT OPERATION

The following protection circuits are built into the MC231CR. When a protection circuit operates, remove the cause before operating the model again.

Overcurrent protection When an overcurrent flows due to an output short circuit, etc., the overcurrent protection circuit automatically limits the current to protect the FET. Remove the cause of the short circuit, etc. before operating the model again.
Heat protector When abnormal heating of the FET due to an overload, etc. is detected, the heat protector operates so that the speed is gradually reduced. When the FET temperature drops, the heat protector automatically resets. However, remove the cause of the overheating before operating the model again.
Low voltage operation When the NiCd/NiMH battery voltage drops, this function limits the motor output current and ensures steering operation. After the speed drops, immediately recover the vehicle.

CHECKER LED DISPLAY

The amp operates linearly in proportion to the amount of forward, reverse, and brake operation. The amp operating state can be checked with the checker LED as shown below.

* Confirmation beep only sounds when the motor was connected.

MC231CR/MC331CR Operation

Forward:

Throttle stick is turned up, the speed increases.

Brake:

Throttle stick is turned down, the brake works.

Reverse:

Operation can be switched to reverse operation by returning the throttle stick from the brake position to the neutral position. Then turn down the stick.

Changing the Neutral Position

Change the neutral position only when large forward stroke of the throttle stick is needed when using an FET E.S.C., etc. (The neutral position is set to the center at the factory.)

*However, when returning from the 2:1 to the 1:1 position (neutral center), return the setting lever to the 1:1 side with the stick lever pushed to the HI side. Otherwise, the setting lever cannot move.

(2) Move the setting lever at the throttle stick body to the outside.

1:1

2:1

(4) Close the front case while being careful that the stick levers, trim levers, power switch, LEDs, and battery contacts do not get caught. And tighten the four screws.

Modifying the Throttle Stick to a Ratchet Type

Open the transmitter front case and modify the stick section. *The ratchet plate (sold separately) is necessary for this modification.

(5) Close the front case while being careful that the stick levers, trim levers, power switch, LEDs, and battery contacts do not get caught. And tighten the four screws.
