Connectors

CAUTION!

• The M8 system uses SANWA New "Z" Connectors. The receiver is blue and should be used only with "Z" connector equipped servos, speed control, switch harness, or batteries.
• The receiver and all "Z" configured components use a different pin polarity than previous servos, speed controllers, switch harnesses, and batteries and should not be used together.

Diagram Description: Two connector types are shown: "New 'Z'" and "Standard". The "New 'Z'" connector has pins labeled S+, S-, and a third pin. The "Standard" connector also shows S+, S-, and a third pin, with a different pinout.

Diagram Description: A diagram shows a "Standard SANWA Receiver" connected via an "Adapter Cable (Z→S)" to a "New 'Z' Connector Servo". This setup is labeled "SANWA Receiver to SANWA 'Z' Servo". Below this, another diagram shows a "New 'Z' Receiver" connected via an "Adapter Cable (S→Z)" to a "SANWA Standard Servo". This setup is labeled "Use Your Standard SANWA Servo with the New Z Connector Receiver".

To use your "Z" connector receiver with previous servos, etc., a Conversion cable (S→Z) must be used or new "Z" connectors installed by the service department. To use previous receivers with "Z" connector servos, etc., a Conversion cable (Z→S) must be used.

Ni-Cd Battery Charging

• Before connecting the charger, both transmitter and receiver power switches must be in the "OFF" position.
• When using Ni-Cd batteries for the first time or if they have not been used for long periods, they may not accept a full charge. If so, they should be discharged and re-charged two or three times.

Diagram Description: A diagram illustrates the charging setup. It shows the Transmitter Charge Plug connected to a Dual Charger, which is connected to a Receiver Battery via a Charge Adapter. A Switch is also shown in the circuit.

Whenever a quick charger is used, the charge rate should not exceed one ampere.

Operation of the Digital Trim

Your SANWA M8 transmitter utilizes a Digital Trim system which eases adjusting the trims while operating your model. Changes as fine as one degree can be made. In addition, it has an Auto-Trim System which memorizes the trim position automatically after running the model.

Steering Trim:

The Steering Trim is used to correct any inherent differences in the right and left turns of a model as determined by its mechanical characteristics.

Caution: When adjusting the Steering EPA, first adjust the Steering Trim as follows: (1) Reset the trim. (2) Set the servo neutral. (3) Adjust the servo center with the Sub-Trim.

Diagram Description: Illustration of the Steering Trim dial on the transmitter.

Throttle Trim:

The M8's Center Trim is not affected by the settings of the throttle high or the amount of brake, therefore changing the neutral adjustment will not affect the brake setting.

Diagram Description: Illustration of the Throttle Trim dial on the transmitter.

EXP (Exponential)

This M8 function modifies the servo (or ESC) action in relation to the movement of the steering wheel or the throttle trigger. Adjusting it in the Positive (+) direction will quicken the action from neutral; adjusting it in the Negative (-) direction will lessen it.

Diagram Description: Graphs showing Steering Exponential and Throttle Exponential curves, illustrating linear operation and exponential adjustments.

ST EXP (Steering Exponential)

Three settings, QUICK, LINEAR and MILD will allow you to set the steering response to that most effective for your particular model. Generally, if your model over-steers, adjust the ST EXP towards the Negative (-) direction. If it under-steers, adjust it towards the Positive (+) DIRECTION.

1. Depress the Function Select Key to move the cursor to ST-EXP.
2. If the steering response is too fast, depress the DEC.- Key to lessen it.
3. If the steering response is too mild, depress the INC.+ Key to increase it.
4. If you opt not to use the Steering Exponential or can not decide on the proper setting, set it to 0% (Linear).

Diagram Description: LCD displays showing ST-EXP adjustments from default to negative and positive values.

EXP TH (Throttle Exponential)

Three settings, QUICK, LINEAR and MILD will allow you to set the throttle response to that most effective for your model. Generally, if an R/C car track is slippery or the model is over responsive to throttle, set the EXP-TH towards the Negative (-) direction. If the track provides high traction or if more torque is desired, set it towards the Positive + direction. The throttle high and brake can be adjusted independently.

1. Depress the Function Select Key, move the cursor to TH-EXP.
2. If the power is applied too rapidly, depress the DEC- key and adjust it towards the Negative (-) direction.
3. If the power response is too mild, depress the INC+ key and adjust it towards the Positive (+) direction.
4. To re-adjust the brake, depress the Scroll Key to EXP-BR and adjust it with the INC.+ or DEC.- Keys.
5. If you opt not to use Throttle Exponential or can not decide on the proper setting, set it to 0% (Linear).

Diagram Description: LCD displays showing TH-EXP adjustments for high throttle and brake.

SPEED (Servo Speed)

This function sets the speed at which the servos (or ESC) will respond. This assures you of smoothly controlled turns and precise throttle control.

ST SPEED (Steering Servo Speed)

This function sets the speed of the servo relative to the steering wheel rotation. It can be set independently for initial servo operation and its return to neutral. However, if the steering servo speed is set lower than the actual speed of the servo, its speed is not affected.

1. Depress the Function Select Key and move the cursor to ST-SPEED.
2. To decrease the initial servo speed, depress the scroll key to display ST-FWD and adjust the value with the DEC.- Key.
