1. For Your Safety:

Keep Clear: Never put hands, feet, or anything near the propeller when it's plugged in. It can spin without warning and cause injury.
No Water, No Power: Do not run the thruster in air for more than 10 seconds. It needs water to cool itself or it will break.

2. For The Thruster's Safety:

Check Seals: Always check that the rubber O-rings are clean, greased, and undamaged before putting it in water.
Avoid Debris: Keep it away from weeds, sand, and plastic bags. These can jam and break the propeller.
No Regular Glue: Do not use normal threadlocker (screw glue) on any screws. It will crack the plastic body. Only use a kind that is safe for polycarbonate.

3. Simple Rules:

Test First: Always test in a bucket or pool before going to open water.
Rinse After Use: Always rinse with fresh water after use, especially in saltwater.
Store Safely: Keep it in a case to protect it from bumps and dust.

1. Two Propeller Types:

You get two propellers: one labeled "CW" (spins clockwise) and one labeled "CCW" (spins counterclockwise).

2. How Thrust Works:

Forward Thrust (Recommended):A CW propeller pushes best when spinning clockwise.A CCW propeller pushes best when spinning counterclockwise.✅ Use this for maximum power and efficiency.
Reverse Thrust:Both can also spin the opposite way to push backwards.⚠️ This works but is weaker and less efficient.

Quick Tip: Always check the label (CW/CCW) to make sure you have the right propeller installed for the direction you want to go. For the strongest push, use forward thrust.

The Thruster: The main unit, which contains a brushless DC motor.

Power Source: A battery pack or power supply.
A Controller: Something to tell it how fast and which way to spin (e.g., a remote control).

How to Connect It:

If your thruster has a built-in ESC:
You can often connect it directly to a standard PWM receiver.
Important Note on Power:
If your receiver or ESC does not have a BEC (Built-in Eliminator Circuit) to power itself, you will need to add a separate BEC module. This provides the necessary power for the electronics.

It's normal for our thrusters to be loud.They use plastic bushings, so small movements between parts can cause sound. This noise is greatly reduced underwater, as water lubricates and cools the system.Never run them dry for more than a few seconds—it can permanently damage the bearings. Every thruster is tested to work properly.
