[APISQUEEN Official Tutorial] U01 Underwater Thruster Two Set Installation Guide

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 docking
Connect the three-phase line of the U01 thruster to the 45A ESC interface

 

 

③Control system construction
Connect the ESC signal line to the A300 remote controller receiving module (white signal line aligned with the marked direction)

 

 ④Channel configuration
• Connect the left thruster ESC to the CH1 channel
• Connect the right thruster ESC to the CH2 channel
(APISQUEEN receiver uses a dual-color LED indicator, which displays green when successfully connected)

⑤ Power Integration
Connect the XT60 input terminal to the adapter module, and the output end to the receiver 3-5 channels (APISQUEEN power module has overload protection function)

⑥Plug the output end of the power supply module into any channel 3-5 of the receiver. Pay attention to the connection direction. The white wire should be connected in the direction marked with a number (the function of the power supply module is to power the receiver. This product's ESC does not have a built-in power supply module, so an external power supply module is required).

  

⑦⑧Turn on the remote control, and then connect the adapter cable to the power plug.

 

★★★After connecting the power supply, wait for the ESC to pass the self-test (prompt sound: beep~beep~beep~~beep~~~~beep~).

  

[APISQUEEN control logic detailed explanation]
Precise control through the A300 remote control:
▲ Push the stick forward: dual thrusters rotate forward (generating forward thrust)
▼ Pull the stick backward: dual thrusters rotate backward (emergency brake/reverse)
← Turn left: right thruster rotates forward + left thruster brakes
→ Turn right: left thruster rotates forward + right thruster brakes

Troubleshooting:
▷ Abnormal steering: swap any two phases of the three-phase line of the ESC
▷ Insufficient thrust: check whether the APISQUEEN ESC waterproof rubber sleeve is intact
▷ Signal interruption: restart the A300 remote controller frequency binding program
