Responsive control from the Futaba BLS253 brushless unit

The Futaba BLS253 delivers targeted performance for 3D helicopter flying. Its brushless motor design and solid construction make it a reliable choice for pilots who demand steady, repeatable inputs.

Built for demanding 3D manoeuvres

Sized for standard 3D helicopters, this servo features metal gearing and two ball bearings to reduce friction and wear. The BLS253 achieves a response time that is 30% faster than many traditional digital servos, while matching the power usage of similar brushed models.

Complete accessory pack for installation

The servo arrives with a selection of horns and mounting fittings to match various helicopter layouts. You will find a universal connector, several round horns, a multi-point horn and the required screws, eyelets and grommets to install the unit cleanly.

Specifications

  • Torque: 117 oz-in (8.4 kg/cm) @ 4.8V; 147 oz-in (10.6 kg/cm) @ 6.0V
  • Speed: 0.13 sec/60 deg @ 4.8V; 0.10 sec/60 deg @ 6.0V
  • Size: 1.6 x 0.8 x 1.5 inches (40 x 20 x 37 mm)
  • Weight: 2.0 oz (58 g)

The Futaba BLS253 is a solid upgrade for pilots looking to tighten control feel and extend servo longevity in 3D helicopter builds.

Is the BLS253 waterproof?

The BLS253 is not specified as waterproof. Avoid flying in heavy rain and keep moisture away from the case and connectors.

Will the supplied horns fit my swashplate?

The pack includes common horn sizes and a multi-point horn. Verify spline and horn geometry against your swashplate before final fitment.

Can I use this servo on tail or cyclic?

Yes, its speed and torque make it suitable for cyclic and some tail applications on standard-size 3D helis. Confirm torque needs for heavy tail loads.

What voltage gives the best performance?

You will see higher torque and faster speed at 6.0V compared to 4.8V, as noted in the specifications. Match your power supply to your flight requirements.
