APISQUEEN's propulsion systems (U2/U5/U92/U10/AQ1020/MU7 series) are engineered for reliability, but can occasionally experience yaw drift due to mounting alignment, remote calibration or uneven load distribution. Here's how we troubleshoot adjustments:

Quick Diagnosis: Identify common triggers such as misaligned propellers or an uncalibrated remote controller.
Professional Adjustment: Use the A300 remote controller's intuitive trim controls (left/right trim keys) for real-time yaw correction.

For persistent issues, the APISQUEEN technical team (lynn@Underwaterthruster.com / nina@Underwaterthruster.com) offers tailored solutions.

This article mainly explains the usage and functions of the A300 remote control. How to use the remote control: First, we turn on the remote control, then connect the power supply, and wait for the device to pass the self-test before starting to use it. Push the remote control joystick upward, the left and right propellers blow air forward and move forward.Pull the remote control joystick downward, the left and right propellers blow air backward and move backward.Push the joystick to the left, the left propeller blows air backward, the right propeller blows air forward, and turns left.Push the joystick...

What to do if the underwater thruster unit suddenly stops working? Generally, both propellers are not working or only one propeller is working. Case 1: Both thrusters do not rotateThere are several possibilities: 1. The power connection is poor. There is no prompt sound when connecting the power. You can check whether there is a voltage display on the remote control screen. If it is 00.0v, the power is not connected properly.Please reconnect the power supply. The thruster will make a prompt sound. The remote control screen will display the current battery voltage. Then try to push the joystick to...
