Yeah Racing MT-4 MT-4S Telemetry Sensors Upgrade Kit for Brushless Motor #YE-0020

Introduction:


Yeah Racing MT-4 MT-4S Telemetry Sensors Upgrade Kit is specially designed for Sanwa MT-4 MT-4S telemetry system. The original MT-4 telemetry system is renowned for its innovative incorporation of temperature and RPM sensors and telemetry system in its kit. The Upgrade Kit is a replacement of the 2 kit sensors and aims at simplifying installation and provides even more accurate and stable sensor readings for RC enthusiast.

Designed to Simplify:


Yeah Racing MT-4 MT-4S Telemtry Sensors Upgrade Kit integrates both temperature and RPM sensors into one small unit. This small unit is then mounted to a specially-designed aluminum mount which also provides pre-drilled mounting positions for 25mm / 35mm cooling fan. The entire unit can then be mounted to the motor just like a normal clamp-type heatsink.

Temperature Sensing:


The temperature sensor, which has the same level of accuracy as the original one, is strategically positioned underneath the PCB with flexibility to adjust to an optimal position of just touching the motor body for precise measurement.

RPM Sensing (for Brushless Motors ONLY):


RPM sensing can never be easier with the MT-4 Sensors Upgrade Kit. By capturing the magnetic field generated around the brushless motor using specially-designed electronics and antenna on the PCB, it can convert the captured data into RPM signal for the MT-4 telemetry receiver. Accurate measurement at over 100,000rpm in real time is feasible!
This completely contactless approach provides the following benefits:
  • No clumsy installation (and subsequent maintenance) of IR sensor and reflective tape
  • Genuine RPM reading of the motor rather than the spur gear
  • In-car vibration and dirt will not interfere your readings any more

  • Installation and Calibration


    1. Secure the sensor board to the mount using the supplied screws (Figure 1)
    2. Adjust the angle of the temperature sensor so that it should be touching the motor body firmly after mounting on the motor (Figure 2)
    3. Clamp it to the motor (Figure 3)
    4. Position the mount as close to the pinion side as possible for better RPM sensing
    5. Make sure the temperature sensor is touching the motor body.
    6. Connect the supplied wires from the sensor board to the RX-461 receiver.
    7. Connect the car battery, switch on the radio and the ESC.
    8. Switch the MT-4 transmitter to telemetry mode. (Figure 4)
    9. Pull the throttle slowly and you should see RPM reading.
    10. If there is no RPM reading, slowly adjust the trimmer on top of the sensor board while applying throttle until you get reading on the transmitter.

    Include:

  • Sensor (1 pc)
  • Receiver Temperature Cable (1 pc)
  • RPM Cable (1 pc)
  • Motor Mount (1 pc)
