The throttle is not at the bottom position or the throttle range is too short.

No receiver signal is detected. Please check the connection of receiver.

The throttle is at the maximum position or the throttle setting is reversed. Please check the throttle settings.

Yes, it can support 4.35V. Therefore 12S is 12Sx4.35V=52.2V。

Yes. Its wiring method is the same as SBUS. And you must choose IBUS in the receiver option of betaflight

Open the UART2 port in betaflight then the data can be displayed.

Flight Control Board: betaflight_SPRACING 3.1.02; OSD: MWOSD1.63; ESC board：A-H-30 BLHeli-S 16.5

1. The connection of the cables which connecting to the motors should be reversed.

2. The steering system of the car differs to regular steering systems.

1. Check if the receiver is interfered and check the remain power of the battery.

2. Replace a new battery if the battery voltage is too low.

3. It can be over-heat protection is triggered. Wait a few minutes to have the ESC cooled off.

1. Replace battery with stronger discharge ability.

2. Replace lower speed motor to increase reduction ratio.

3. Set the start mode to lower level.

1. Check all the connections

2. Check all soldering points

3. Contact FLYCOLOR to repair.

Reset the throttle range.

1. Check the plug of motor cables or solder motor cables again.

2. Change a new motor.

The battery voltage is too low to drive the boat. Replace it by a fully charged battery.

1. Check the connection of signal cables and receiver.

2. Check transmitter and receiver make sure the communication is functional.

Pull the throttle stick to bottom position or reset the throttle range.

Choose proper setting of throttle forward or backward.

1. Switch any two cables of the three cables connecting ESC and motor.

2. Use remote controller or program card to reverse rotation of the motor.

1.Set proper value of Low Voltage Protection. When the protection is triggered the boat would be running at Low Power Mode. And it means you should retreat your boat.

2. The boat should be running in the range of remote controller. Mind the battery voltage of the remote controller.
