Frequently asked questions
Q1:How much thrust do I need for my ROV / kayak / project?

A: It depends on your total weight and desired speed.

Thrust Typical Use

1–5 kg Mini ROV, inspection

5–20 kg Kayak, small boat, medium ROV

20–50 kg Commercial ROV, aquaculture

50–100 kg Industrial, deep-sea

Not sure? Tell us your weight + speed + environment, and we'll recommend a model.
Q2. PC vs aluminum – which material should I choose?

A: Both can reach 300m. PC is lighter and naturally corrosion-resistant. Aluminum is stronger and more impact-resistant.

Example: TD7 V2 uses PC housing at 300m depth (5.6kgf thrust).

  • Choose PC → weight-sensitive, cost control
  • Choose aluminum → heavy-duty, extra-deep (300m+)
Q3:Do you support customization?

Shipping is calculated based on your location and the items in your order. You will always know the shipping price before you purchase.
Q4. Can you make custom motors? What about DIY waterproofing?

A: Yes – we design and manufacture custom motors for your specific application (thrust, size, voltage, mounting, etc.).

As for DIY waterproofing of generic motors:

  • Not recommended. Generic motors lack proper sealing and corrosion-resistant bearings. They often fail within hours underwater.
  • Our solution: Purpose-built thrusters with multi-stage dynamic seals, ceramic/stainless steel bearings, and full pressure testing – 500+ hours rated life.

Tell us your requirements. We build the motor right for underwater use.
Q5. Is the ESC included? What control signal do you use?

A: You can choose motor only or motor + ESC. All our thrusters use PWM signal – the industry standard, compatible with most RC transmitters and flight controllers.

Options:

  • DIY kit → thruster + cable
  • Ready-to-run kit → thruster + waterproof ESC + wiring

Need a different signal type? Contact us for custom options.
Q6:Where are your products manufactured?

Our products are manufactured in Shenzhen China.We carefully select our manufacturing partners to ensure our products are high quality and a fair value.

Q7:When will I get my order?

We will work quickly to ship your order as soon as possible. Once your order has shipped, you will receive an email with further information. Delivery times vary depending on your location.Kindly check our shipping policy
