Underwater Thruster 1.2kg Thrust 12V Brushless Motor with bi-directional full waterproof ESC for ROV,RC Boat,Underwater Vehicle,Diving,Seafloor Photography,Seabed Exploration (CW)

So this thruster could be confusing if you’ve never worked with RC electronics before, but it uses a standard ESC that is plug and play with a standard RC transceiver. Hook the red and black wires to 12v hot and ground respectively. Hook the yellow wire to the signal (S) pin on your RC receiver. Make sure your receiver is using a common ground with the thruster. After turning on your receiver, the thruster should play a tone that indicates that it has been initialized. It just worked for me. I used this thruster to propel a standup paddle board controlled via an esp32 and later a normal RC receiver. At 100% PWM at 12v, it goes a little faster than a strong paddle. At around 60%, I can keep up with a casual paddler.

5/5 stars. It works exactly as stated. Ignore all the comments stating that the wiring instructions are wrong. I received the motor with 4 wires, and followed the instructions, red and black go to your battery, yellow and white go to the exact spots on the receiver as shown in the instructions. The only addition I'd have to those instructions is that you must turn it on, then off, then back on. After turning it on the 2nd time, that's when the motor beeps 3 times and then works as normal. It took a few tries to figure that out.

Theyre too small. Powerful, yes, but too small. Good size for an rc bait/fishing boat.

I was hopeful for this Diamond Dynamics thruster because it has an attached ESC, which was appealing for my project. However, I was never able to power up the thruster from a Raspberry Pi. The thruster would power up using the HiLetGo Servo Tester, but not from the Pi. After much machinations to get it working, the ESC finally failed. Then, purchasing two standalone ESCs and one new ESC-less thuster (APISQUEEN U2 Mini), and removing the ESC from the Diamond Dynamics thruster, all combinations of ESCs and thusters immediately worked fine from the Pi. Note to Pi users, the 3.3V logic output needs to be bumped up to 5.0V, I used the HiLetGo TXS0108E Level Converter. Bottom line is that I can't recommend this product, it might work for you, but I'd say its not worth the trouble to find out.

It has a lot of power and cheap enough. The complain I have is no BEC. Follow the instruction come with and you are good to go.
