Accurate control from the Futaba BLS253 brushless servo

The Futaba BLS253 is engineered for 3D helicopter pilots who require consistent, linear control. Its brushless design and solid mechanical layout support reliable inputs during aerobatic flight.

Suited to aggressive 3D flying

This standard-size servo uses metal gears and two ball bearings to ensure smooth operation and reduced wear during high-demand manoeuvres. The BLS253 boasts a response time roughly 30% quicker than many conventional digital servos, while consuming comparable power to brushed units.

Supplied mounting hardware and horn options

The box contains an assortment of horns and fitting hardware to match most helicopter arrangements. You get a universal connector, several round horns, a multi-point horn plus the screws, eyelets and grommets required for fitting.

For builders and fliers focused on precision and durability, the Futaba BLS253 represents a dependable servo choice for 3D helicopter applications.

Yes, with correct ventilation and proper mounting it will cope with extended session use. Monitor bearing wear over time and replace if play develops.
It is compatible with common digital gyros and flight controllers. Ensure signal latency and travel settings are tuned for optimal response.
Confirm horn alignment, spline compatibility and that mounting holes match your frame. Secure the grommets and eyelets to reduce vibration transfer to the servo case.
Watch for worn gear teeth or bearing play after heavy use. Keep connections clean and avoid overloading the servo beyond the listed torque ratings.
