Precision Tail and Control with Futaba GY611_BLS251

The Futaba GY611_BLS251 set pairs the GY611 AVCS Gyro with the BLS251 Brushless Servo to refine control feel and heading stability. Designed for hobbyists who fly dynamic routines, this combo supports clean inputs and consistent response.

Sharper Yaw Control from the GY611 AVCS Gyro

The AVCS technology in the GY611 reduces unwanted rotations and improves yaw stability. That translates into steadier tracking during transitions and tighter control during hover work.

Responsive Drive from the BLS251 Brushless Servo

The BLS251 delivers quick actuation and steady torque, with the efficiency benefits of a brushless motor. It integrates smoothly with the gyro to provide accurate control across a range of flight conditions.

Specifications

  • Voltage: 4.8V - 6.0V
  • Torque: 4.8V: 2.5 kg/cm, 6.0V: 3.0 kg/cm
  • Speed: 0.10 sec/60° at 4.8V, 0.08 sec/60° at 6.0V

Futaba GY611_BLS251 is a solid option for pilots wanting tighter control and reliable performance without complicated setup changes.

What power supply is recommended for the BLS251?

Use a stable 4.8V to 6.0V supply and ensure your BEC or battery can handle the servo current at peak load to avoid voltage sag during aggressive manoeuvres.

Will the gyro need frequent retuning?

Once mounted correctly and with initial gains set conservatively, the GY611 usually requires only minor adjustments to suit flying style and helicopter setup.

Are replacement parts available for the servo?

Service parts depend on the supplier, but brushless servos often have replaceable gears and bearings. Check with your retailer for specific spare components for the BLS251.

Can I pair this combo with my existing flight controller?

Yes, the GY611 can work alongside many flight controllers as long as signal routing and control priorities are set so the gyro handles tail correction correctly.
