2. Is it bluetooth remote?
No, it’s 2.4ghz remote.
3. Can it be used for Efoil and Esk8?
Yes, it has two control modes. You can adjust Esk8 mode or Esurf mode according to your using.
4. What’s the difference of Esk8 and Esurf modes?
Esk8 mode is for electric skateboard with brake function;
Esurf mode is for electric surfboard efoil without brake, with cruise control function.
5. Can I use the smart phone wireless charger to charge the remote?
Yes, it’s QI standard wireless charging interface.
6. What is the screen size?
128x64 OLED, yellow and blue screen.
7. What data can the screen show?
For all PWM ESCs, it can show Battery voltage, Throttle Percentage:
In ESK8 mode: It can also show speed, distance, and if use with VESCs, it can show motor and ESC temperature, current:
In Esurf mode: It can show motor RPM, and if use with VESCs, it can show motor and ESC temperature, current:
8. How long transmission distance is the remote and receiver?
Air 10M; Water 1M.
9. How to pair remote with receiver?
-If remote and receiver are paired successfully before, then no need to pair them again.
-If remote and receiver does not get paired before, please pair them according to below steps:
- Turn off receiver.
- Select【>4.Pair】and long press function button for 1 second to enter pair status. When screen shows 【Paring…】, turn on receiver and it will auto-pair with remote control in 0.5 second. Red led lights steady. Pairing competed. Remote screen will automatically return to main menu. If auto-pairing time is over 1 second and screen still shows【Pairing…】, pairing fails and it needs to turn off and turn on receiver again to pair them. If you don’t want to continue the pairing process, long press function button to exit to main menu.
10. How to do remote calibration?
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.
Select【>5.Calibration】and long press function button for 1 second to enter Sub-menu. Once enter calibration, it must need to be finished. If don’t continue calibration and exit, remote and receiver will stop working together.
Press throttle trigger to top and loose it. Then press brake trigger to top and loose. When press trigger, the screen will prompt【Calibrating】 and 【 Cal. OK】.
After both two are【 Cal. OK】, long press function button to return to main menu and save the results.
11. Can I use 5.5V to supply power to receiver?
Yes, the receiver can accept max 6V.
12. Can it work with non-Maytech ESCs?
Yes, it’s standard PWM signal and can work with other PWM ESCs.
13. Can it communicate and gain the data from official VESC firmware?
Yes, all Maytech VESC based controllers are with official VESC firmware, the remote firmware can work with official VESC firmware ESCs.
14. What is the antenna connection type to the MTSKR1905WF receiver?
It’s IPX type connector.
15. Can I extended the antenna or cut it?
The antenna can’t be cut or extended randomly. Please buy the standard 2.4ghz signal antenna and replace the old one. We also have 1m/1.5m/3m antenna.
16. How does SWI work?
-Connect the SWI switch, your LED light and 3S battery as following shows.
-When (Short press Function button three times) transistor switch is on (display of 【2】in Screen Main interface), transistor switch source will be connected to GND and turn on LED. When it’s off(no display of【2】in Screen Main interface), LED is off.
17. How does Relay Switch work?
-Max current of relay switch contacts is 3A. Recommend use this switch for water pump or main lighting system. Recommend to connect as following:
-When relay switch is in original position(no display of【1】in Screen Main interface) , COM(common point) and CLO(normally close) are connected.
-When Short press Function button two times (display of【1】in Screen Main interface) , COM(common point) and OPE(normally open) are connected.
18. Water get in the screen, will it damage the remote?
No. The Screen is sealed with waterproof Nano coating, not glue. When use it in water, water will get in between the outside and inside screens. It won't influence remote working. When you don’t use it, please put it in dry place and it will dry slowly.

-Connect wireless charger to power, put remote Charging Point right on the wireless charger; it will automatically charge after 2 seconds.
-Remote screen will show charger input voltage “Input” and current battery voltage “Batt.”.
-When remote battery gets to 4.2V, it will stop charging automatically.The screen displays voltage data all the time and will not shut down automatically. Please don’t put remote on charger for longtime after full-charged!
-Charging without supervision is prohibited!
-When the remote control is not used, please charge it once a month, otherwise the battery life will be shortened or even scrapped due to long-term power loss.
