Futaba S9250 - Precision coreless servo for tight control

The Futaba S9250 digital servo is designed for pilots who need crisp, repeatable inputs in helicopters and aeroplanes. Its coreless motor and dual ball bearings reduce inertia for quicker response, while metal gears provide the strength required for sustained high-torque use.

Notable Features of the S9250

Coreless Motor: Low rotor inertia gives faster reaction to control commands.
Metal Gears: Robust gearing improves resistance to wear and shock.
Dual Ball Bearings: Reduces play for steady, accurate servo output.
High Speed: Rated at .11 sec/60 degrees at 4.8V for quick corrections.
Dust and Water Resistant: Seals help protect internals during outdoor flying.

The S9250 gives dependable speed and torque for accurate cyclic and collective control, making it a sensible upgrade for experienced flyers.

Will the S9250 handle cyclic loads on 3D models?

The S9250's metal gears and rated torque suit many aerobatic and 3D models, but always match servo speed and torque to your model's size and load profile for reliable performance.

What electronics pair well with this servo?

Use a stable BEC or regulated battery pack at the recommended voltage, and ensure your receiver and governor (if present) can supply consistent current under peak loads.

How do I keep the servo clean after dusty flights?

Wipe the exterior, avoid high-pressure washes, and check seals and linkages for grit. Periodic inspection of gears and bearings will prolong service life.
