PROFESSIONAL 

QUALITY

Weighing just 3.3kg, the S900 has a maximum takeoff weight

 of 8.2kg. This means you can easily carry most cameras and

 gimbals. Used with a 6S 12000mAh battery, it can fly for up

 to 18 minutes*.

*Maximum flight time is tested on a breezeless day with a payload of 6.8kg, hovering

 at a height of 2 meters.

WIDE RANGE OF SHOOTING ANGLES

Retractable landing gear and a special low gimbal mounting bracket gives you an extremely wide

 range of possible shooting angles and camera motions.

 GIMBALS

DJI’s Zenmuse camera gimbals are known for their stability, providing smooth footage

REDUCED VIBRATIONS, CLEARER

 FOOTAGE

The S900’s gimbal bracket is separated from the main frame by specifically designed

 dampers. This significantly reduces high-frequency vibrations and makes your shots

 clearer and sharper.

GREATER POWER

A 40A electronic speed controller (ESC), our fastest available, is built in to each arm.

 The 4114 pro motors, high performance 1552 folding propellers, and V-type mixer

 design combine to give each arm of the S900 a maximum thrust of 2.5Kg.

Our latest motor adopts a single wire stator design, offering improved heat dissipation,

 better performance, and a tidier, more reliable system.

14
INNOVATIVE ARM DESIGN

Each arm is designed with an 8° inversion and a 3° inclination, making the aircraft more

 stable when rolling and pitching, yet more flexible when rotating.
