Knowledge — Remote Control

We are excited to introduce the upgraded version of our remote control system — the APISQUEEN W300 Wireless Waterproof Remote Controller. As a major upgrade from the previous A300 2.4G 6-channel Remote Controller, the W300 retains all the proven core features while significantly improving water resistance and overall reliability, delivering a safer and more dependable control experience for marine environments. ⚠️ The product is currently undergoing final optimization and testing for GPS and wireless functions. Features will be finalized in the official release.  Why This Upgrade? Over time, we’ve received valuable feedback from many of our users: “The controller works great,...

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.
