Functional Features

Motor lifespan

Enable your aircraft to fly 1500 flights with ease (40 minutes/flight)

Imported custom bearings

Based on the axial and radial working conditions

of the motor, simulation analysis is conducted to

redesign and customize the bearings to achieve a

normal operating life of over 1000 hours.

New iron core design

The new U10 adopts a brand new iron core,

and after repeated testing and comparison of

various parameters of the iron core, it took several

months to choose this brand new iron core.

While generating greater tension and higher force

efficiency, the self weight is minimized as

much as possible.

Imported custom silver wire winding

Make the current flow faster through the surface of the silver wire,

improve the responsiveness of the motor control, and make it easier

for you to control the aircraft.

At the same time, it significantly reduces the copper loss of the motor, reducing its heat generation by 30%.

Dustproof and Waterproof

Motor protection

We are more attentive, and users are more at ease

Protection level IP45

Even in the rainstorm environment, it can fly calmly,

Flying in desert areas is not wrong.

Foreign object isolation

New dustproof net

Gravel, dust, foreign objects, and magnetic particles are all kept out.

Dust net aperture<1mm

Special rust prevention

Salt exposure test

Iron core

Special rust prevention treatment technology,

The rust prevention ability can pass the 48 hour salt spray test.

Efficient heat dissipation

Even when working in hot weather, one can confidently take the field

Centrifugal air cooling system with built-in high-efficiency heat dissipation array, excellent heat dissipation performance provides strong guarantee for the reliability of motor operation.work calmly at an ambient temperature of 50 ℃.

Performance Demonstration

The maximum tensile force of U8 Ⅱ reaches 7.3kg

power pull

Heavy load

Due to the decrease in motor operating temperature,

the maximum pulling force of the new U8 has been

increased from 5kg to 7.3kg, making it easy to double

the payload of the aircraft.

Maximum power Maximum tensile force

The maximum tensile force of U10 Ⅱ reaches 10.6kg

Heavy load

Due to the newly designed iron core of the motor, the maximum pulling force of the new U10 has been increased from 8kg to 10.6kg, significantly increasing the payload of the aircraft.

Maximum power Maximum tensile force

power pull

The maximum tensile force of U12 Ⅱ reaches 20.4kg

pull

Heavy load

Due to the newly designed iron core of the motor,

the maximum pulling force of the new U12 has been

increased from 13.6kg to 20.4kg, significantly increasing

the payload of the aircraft.

U8 Ⅱ Silver collar fashion, smart driving the world

FOC electric tuning enables your power system to be finely controlled, produce less noise, and improve traction efficiency.

Sine wave driving method FOC ESC Ultra light paddle combination

New ultra light 28 inch carbon propeller, weighing less than 55g

(standard 28 inch carbon propeller weighs 98g).

If U8lite is paired with ultra light propellers,

it can reduce the weight of your quadcopter

by 320g and increase flight time by 12%.

No need for additional paddle seats, weight reduction of 20g, easier installation

Tip: Don't forget the 2g positioning pin!
