E1200 Pro Tuned Propulsion System Upgrade for The s900.
- Integrated Structure
For ultimate convenience, the E1200 Pro’s integrated ESC,
motor, and propeller are designed as a single unit that can
be installed quickly and easily on the arm
of any compatible platform. It also enables
a total solution for heat dissipation
- 17-Inch Ultra-Carbon Folding Propeller
As one of the largest members of the Z-blade series, the 17-inch propeller boosts both
efficiency and thrust. The application of advanced ultra-carbon-fiber composite, provides the
rigidity of a metal propeller with lower inertial momentum. The classic folding design protects
the propellers while making transportation and use as simple and efficient as ever.
- Motor & ESC Cooling System
A built-in centrifugal fan provides active cooling for both the ESC and the motor. Grid-shaped structure in the top allows for adequate ventilation while keeping dust and other debris out. The dissipation area of the integrated base plate has been enlarged by 200-300%, greatly enhancing passive cooling of the system.
- Next Generation Smart ESC
The sine-wave drive ESC increases power efficiency by capturing energy that is produced during deceleration. Active braking provides better dynamic response. Dynamic battery voltage ripple compensation maintains a linear speed-throttle relationship, making the flight control experience more fluid and stable.
- Breaking Limits
When using the E1200 Pro to upgrade your S900 using a standard 6S battery, flight endurance can be extended by nearly 30% *, assuming a consistent takeoff weight. With greater thrust, the maximum take-off weight can be increased by 1.8kg*.
Moreover, the E1200 Pro is capable of working in environmental temperature up to 60˚C and is capable of taking-off at altitudes 2000m higher than previous generations.

About The Arm Tube
Each of the S900’s arm tubes is riveted to its motor base, which may make disassembly difficult for some users. The E1200 Pro Upgrade Kit for S900 includes an arm tube so that the entire arm system can be completely replaced.
Remounting the Propellers
1) Use two foldable propeller mounting screws (M3×12.5 hexagon), the two propeller cover mounting screws (M3×8), and the four propeller washers to remount the propellers.
2) First apply thread locker to the thread of the propeller mount, then tighten the screws until the propeller blades are securely clamped and can rotate freely.
Propeller Precautions
Check the markers on the screws and propeller covers before every flight. If the propellers are loose, the markers will provide a visual cue, indicating that the screws should be tightened.
Assembling Motor Vibration Absorbers
Affix the motor vibration dampers. First insert the dampers, then tighten the four screws on motor base mount (M3×12 hexagon). The assembly process is identical for both the lockwise and counter-clockwise propellers.
