FAQ18: Does Maytech MTSKR1905WF remote has forwarder/reverse function?

In Esk8 mode has forwarder/reverse function, not in Esurf mode.


FAQ19: How to use forwarder/reverse function?

Please noted: this function is related to your VESC / ESC speed controller, if your VESC / ESC also has forwarder/reverse function, then you can use this function, if not, the this function can’t be used.

  • You need to open forwarder/reverse function in your VESC / ESC speed controller, then the remote can use this function automatically, when this function is open, throttle trigger on remote charges forwarder, brake trigger on remote charges reverse.
  • Brake trigger charges reverse, how can I brake?

   Brake function is also related to your VESC / ESC, if your VESC / ESC has brake function, you need to open this function, and adjust duty cycle percentage in VESC_TOOL, this percentage value is related to throttle percentage, when you need to slow down, release the throttle trigger on the remote slowly, the smaller the throttle percentage, the slower the speed.

    Or you can add a mechanical brake.


FAQ20: When I press the trigger to top, the throttle or brake percentage on the screen is not 100%, why is that happen and what should I do?

Due to environmental changes during use, remote calibration may be out of proportion to the output of PWM signal. Then it needs to do calibration.

Our MTSKR1905WF remote has calibration function, you can do the calibration in the remote, and your ESC don’t need to have calibration function.

FAQ23: Tips you need to noted when use the Transistor switch on the receiver of Maytech MTSKR1905WF.

If you use transistor switch, you need to add another 12V battery for this switch, because main battery voltage is too high, if directly use main battery, would easy burn MOS tube.

Suggest to use Transistor to control light on Esk8, relay switch to control pump on Esurf.

Relay switch can also use to control light on Esk8 , and it doesn’t need another 12V battery, can directly use main battery to power, but relay switch is mechanical switch, the light needs to be on and off often, which would easy cause the switch loose and shorter the switch lifespan.
