Knowledge — Thruster

APISQUEEN water tube ROV has the following features:
①Supports forward, backward, in-situ turning, and heave movement;
②Modular structure, convenient for teaching demonstration and disassembly and maintenance;
③The propulsion system uses high-efficiency waterproof motors, which are suitable for various water environments;
④Especially suitable for teaching experiments and popular science education in primary and secondary schools, colleges and universities, and scientific research institutions.

As a supplier of underwater equipment such as underwater propulsion, APISQUEEN specializes in solving underwater related problems for water sports enthusiasts. Today, APISQUEEN brings you a complete installation tutorial for the professional-grade U01 underwater thruster twin-engine kit. This set includes: ①APISQUEEN U01 underwater thrusters × 2 (IP68 waterproof rating)②45A brushless ESC × 2 (optional fully waterproof/splashproof version)③A300 professional underwater remote controller (2.4GHz frequency band)④Power supply module (supports 5-25V input)⑤1:3 power adapter cable ①②Thruster dockingConnect the three-phase line of the U01 thruster to the 45A ESC interface     ③Control system constructionConnect the ESC signal line to the A300 remote controller...

BEC (Battery Elimination Circuit) is a micro power module integrated into the ESC, which can directly draw power from the battery and power low-voltage devices such as receivers and servos. APISQUEEN ESC provides two solutions: 30A built-in BEC saves space, and 45A supports expansion of high-power external BEC.

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.
