FAQ

When the battery runs down to 20%, the board's top middle light LED lightning will start flashing.

When you don't need to use the battery, it is recommended to put it in the battery safety box and place it in a dry, cool place. If it is not used for a long time, the battery power should be maintained at 40%-60% during storage.

The Jet ONE controller has 2 types of screen -- 128mmx160mm and 240mmx240mm. Remotes with different screens require different firmware. Wrong version could cause the black-screen issue of a remote controller.

Usually the firmware upgrade app will auto-select the proper version for the remote. If your remote gets the wrong firmware, you can still fix this black-screen issue by re-upgrading its firmware.

4. Re-open the app and click “Scan BLE Device” again.

Don’t mind it. Just click on the “Upgrade” button and continue the upgrade process.

You must have missed some steps. Please read the guide carefully or watch the tutorial videos (refer to Q5 & Q6). Then restart the whole process from the beginning.

No, you can’t. Even though this remote and the mast can get paired. The mast motor won’t respond to the signal from the remote. Please update the firmwares for both of the remote and the mast to the same version.

Probably firmware problem. Please refer Q14.

Phenomenon: If the Subnado is under no-load conditions, for example, the Subnado is idling without being placed in the water, the speed of the propeller will slow down after rotating for 3 to 5 seconds.

Solution: This is the idle protection function and it is the normal phenomenon.

Phenomenon: Subnado cannot be charged, and there are green corrosion marks on the USB-C interface of main unit.

When the user use Subnado in water, the user forgot to install the waterproof cover, or the waterproof cover is not tightened tightly, and sea water enters the USB-C interface, and then the user does not check whether there is water in the USB-C interface before charging, and starts charging without cleaning and drying the USB-C interface, resulting in electrochemical corrosion of the USB-C interface, and the chip of the main control board was damaged.

On the gold finger of the USB-C interface, it can be observed that green electrochemical corrosion marks are left after water enters.

Solution: Send back to China to repair the main control board or buy a new main unit.

Phenomenon: There is no ESC self-check sound (boot sound) when the Subnado is turned on, the indicator #1 is always on, and #7 is flashing.

Solution: Please guide the user to upgrade the latest ESC firmware first.

If upgrading the latest ESC firmware cannot solve the problem, please report to the Waydoo after-sales team for further investigation.

Please let user submit a warranty claim form so we can gather all the necessary information. Our after-sales engineer will reach out to user soon after receiving the form.

Phenomenon: When the user uses Subnado for the first time, there is no ESC self-check sound (boot sound) when the Subnado is turned on, and it cannot be charged, when charging, the indicator #1 is always on, and #7 is flashing.

Solution: Please guide the user to upgrade the latest ESC firmware first.

If upgrading the latest ESC firmware cannot solve the problem, please report to the Waydoo after-sales team for further investigation.

Please let user submit a warranty claim form so we can gather all the necessary information. Our after-sales engineer will reach out to user soon after receiving the form.

Phenomenon: The propeller rotates stuck, but other functions are normal.

Solution: Guide the user to upgrade the V2.15 ESC firmware to solve the problem.

Please update the V2.15 version firmware for Electronice Speed Control, will fix the problem.

If the user does not have the computer required to upgrade the firmware, please refer to the solution as follows.

The propeller could be repeatedly rotated several times to restore the normal state.

First please turn off the Subnado, then unscrew the rear cover of Subnado clockwise, then apply more force to rotate the propeller.

Phenomenon: Press the trigger, the propeller does not rotate or rotates occasionally.

Solution: The issue may be caused by the poor contact of the throttle interface or the thumb wired controller (or handle bracket) is faulty.

First check whether it is caused by poor contact of the throttle interface, if not, replace the thumb wired controller (or handle bracket) for the user.

The troubleshooting steps are as follows.

First please check whether there is boot sound when Subnado is turned on? If there is boot sound, it means that the Subnado main unit is good, the problem may be caused by poor contact between the main unit and the thumb wired controller.

[2] Turn off Subnado and unplug the thumb wired controller, then check whether the 4 circular metal contacts of Subnado for water or corrosion? Please wipe the 4 contacts with tissue or clean soft cloth dipped in alcohol, and take a photo of the contacts after cleaning.

[3] Please check whether the 4 metal pins of the thumb wired controller was stuck or not? If the pins was stuck, please use a small tool such as toothpick to set the pins back to its normal state, and take a photo of the pins after checked.

[4] Turn off the Subnado, unplug and plug the thumb wired controller for 3 to 5 times, and make sure the waterproof cover is rotated to the fixed position (as shown below), and then power on the Subnado to test whether it work well.

At last, if you have other the thumb wired controller (or handle bracket) or Subnado main unit, please try to do a cross test to check whether the thumb wired controller or Subnado main unit has problem.

Phenomenon: The propeller rotates automatically when the trigger is not pressed.

Solution: It may be that there is water between the throttle interface of the Subnado main unit and the controller, or the thumb wired controller (or handle bracket) is faulty.

First check whether there is water between the throttle interface, and whether there are strong magnetic substances or facilities in the surrounding environment. If not, replace the thumb wired controller (or handle bracket) for the user.

The troubleshooting steps are as follows.

Check whether the throttle interface of the Subnado main unit and the controller have water ingress.

1) Turn off the Subnado, unplug the controller, clean the throttle interface of the Subnado main unit, and wipe off the moisture, then turn on the Subnado, connect the controller, and check whether the trigger control returns to normal.

2) Install the controller on other Subnado main unit for testing to see if there is the same phenomenon.

2. Check the surrounding environment for interference from magnetic substances.

Please stay away from magnetic substances or facilities, and then confirm whether the trigger control returns to normal.

After the above investigation, if it is confirmed that the thumb wired controller (or handle bracket) is faulty, please replace for the user.

Phenomenon: The trigger is stuck in the pressed position and cannot automatically rebound to return to the normal position.

Solution: It may be that the trigger is broken by the impact, or sundries objects such as sand enter the trigger, causing the trigger to be stuck and unable to rebound.

Guide the user to check whether sand or other sundries matter has entered the trigger to block the trigger, and whether the trigger has been impacted. If not, replace the thumb wired controller (or handle bracket) for the user.

Phenomenon: Some users reported that they lost the waterproof cover and hoped to buy the replacement of waterproof cover.

Solution: Guide users to buy the replacement of waterproof cover.

If the propeller is involved in debris, especially hard objects, the high-speed rotating propeller blades will be damaged. Users should pay attention to prevent debris from being involved in the propeller during daily use, so as to avoid damage to the propeller or cause other problems. If there are sundries, stop using it in time, and take out the sundries in the off state.

Figure: Damage caused by hard objects getting involved
