U92 300KV support voltage: 12-16V .

Set includes: U92 propeller (12/24V)*1, remote control*1, white sealed box*1, ESC*1, mounting base*1

About ESC:

• 32BIT MCU, very responsiveand smooth.
• Powerful switching BEC and voltage adjustable.
• Waterproof, safe more and enjoy more.
• Premium Mosfets and ceramic capacitors.
• Powerful throttle control: throttle rate, throttle curve and throttle softening values can be adjustable.
• Advanced motor control algorithmdrives perfectly with low speed and get a very powerful acceleration 
• Multiple protections: Low voltage protection, overheat protectionand throttle out of control protection.
• Easy to use and keep upgrading.
• PWM signal control, the input frequency is 50-480HZ, and the output frequency is 8-32khz;
• Bidirectional ESC, 1ms-1.5ms-2ms, 1.5ms is the median value.

ABOUT PWM PWM full name is (Pulse-width modulation). It is also called duty cycle signal, which indicates the proportion of the high level duration to the whole signal period. 2ms for the whole period of PWM, 1.5ms stop, 1.5-2ms forward, 1.5-1ms reverse.From the diagram, we can clearly see that when PWM is 75% (1.5ms), the motor stops rotating, when PWM is 50% (1ms), the motor rotates in reverse, and when PWM is 100% (2ms) the motor rotates in forward.Of course ESC will not only make the motor turn forward and reverse, but can adjust the speed of motor rotation by the duty cycle size of PWM. When the PWM is gradually changed from 75% to 50%, the motor will keep reversing and accelerating from stop until the reverse rotation reaches the maximum. And when PWM is gradually changed from 75% to 100%, the motor is continuously accelerated from stop to forward until the forward rotation reaches the maximum value. That is, PWM is a signal that can be continuously varied, and the effective range is from 50% to 100%.The frequency of PWM signal is 50hz, 100hz, 200hz or 500hz, etc. The higher the control frequency, the shorter the period, the shorter the control interval, and the faster the ESC and motor response speed The faster the ESC and motor response. Conversely, the lower the control frequency, the longer the period, the longer the control interval, and the slower the ESC and motor response.

About Customization

Customization services include: customization of all aspects of thrusters, motors, and ESC;
If you have any customization needs, please contact APISQUEEN (lynn@underwaterthruster.com).

About Tariffs

The product price and shipping cost do not include tariffs. Tariffs are charged differently in each country, and buyers need to pay tariffs when receiving the goods (for example, the tariff policy in the United States: tariffs are exempted within 800 US dollars).

1. International imports from certain countries/regions may require specific materials for customs clearance (if necessary, we will provide customers with pro forma invoices).
2. If the goods are returned due to the customer's failure to cooperate with customs clearance, the freight shall be borne by the recipient.
   
3. We can provide consumption lists and certificates. Please contact us when customs requires.
   
4. If the buyer causes the return, the buyer shall bear the freight, and the cost shall be based on the selected courier. If the goods are damaged or wrong due to our fault, APISQUEEN shall bear all costs.
   
5. The value of the products we declare to the customs is 10% of the actual order amount paid by the buyer, so the buyer generally pays very little tariffs.
   

About Shipping

We can send goods to almost any country in the world! But you need to pay attention to the import restrictions of some countries.In the case of stock: the goods will be shipped within 1-3 working days after the buyer pays.
In the case of no stock: the goods will be shipped within 3-20 working days after the buyer pays.

1. Or there are other problems that delay the shipment, such as the address information needs to be further verified, but please rest assured that we will follow up in time to deal with it so that the goods can be shipped faster.
2. Goods are generally transported by air. According to the buyer's location, we use different transportation methods. Generally, we use DHL, FedEx, UPS, dedicated lines, etc.
3. The time for standard express delivery to the destination is generally 3-12 days (without other special circumstances), and the transportation time for remote countries/regions is generally 10-20 days. If you have other needs (such as designated express, customs value declaration, etc.), please contact us after placing an order to ensure that we can meet your requirements.
4. APISQUEEN sets transportation rates according to different countries/regions. In order to reduce the buyer's purchase cost, APISQUEEN takes the initiative to bear 50% of the shipping costs for the buyer.
5. Shipping costs are charged according to the weight of the goods and are settled when placing an order. The shipping cost shown in the settlement is the result after APISQUEEN bears 50%.
6. You can estimate the shipping cost as follows: select the item you want to purchase → add to the shopping cart → enter the zip code of the delivery address → select the delivery method → ​​then you will receive the estimated shipping cost.

If you need the product urgently, please contact us before placing an order to ensure that we can meet your time requirements.

About after-sales

1. The order can be cancelled before the product is shipped to obtain a full refund (including shipping costs). After the goods are shipped, if the buyer requests a refund for his own reasons (for example: he does not want it anymore, bought the wrong one, etc.), the buyer needs to bear the cost of the express delivery and return the goods to us. After we receive the returned goods, we will refund the buyer.
2. If you find that your package is damaged during transportation, please contact us within 5 days of receiving the goods (Lynn@underwaterthruster.com), and provide photos or videos of the goods. We will handle it for you according to the actual situation within 1-3 working days to satisfy you.
   
3. If you need to replace your purchased goods after receiving the goods, you need to mail the goods to APISQUEEN;Within 6 months after purchasing the product and confirming receipt, if there is any quality problem with the product, we will provide free after-sales service and mail new accessories or new products to the buyer free of charge (the buyer only needs to bear the express transportation fee, APISQUEEN will no longer help the buyer to bear 50% of the freight, and the buyer needs to bear 100% of the freight)
   

APISQUEEN refuses after-sales service in the following situations:

1.  Failures and damages caused by non-product quality problems.
2. Damage caused by circuit changes or improper matching.
3. Damage caused by unauthorized modification or disassembly.
4.  Damage caused by improper installation or use.
5. Failure to clean with fresh water in time after use in seawater, resulting in shortened life.
