Reliable rudder performance from the Futaba BLS257 brushless servo

The Futaba BLS257 Brushless Heli Rudder Mini Servo is a compact, high-response option for 3D helicopters. It delivers roughly 30% faster response than standard digital servos while using about the same power as brushed digital units, and the brushless motor gives an estimated fivefold increase in service life.

Does the BLS257 need special connectors?

The unit ships with a universal connector that fits most receivers; adaptors may be needed for non-standard plugs or older systems.

How do I set up endpoints for aggressive 3D flying?

Limit endpoints and use subtrim to achieve the desired throw while keeping control smooth; small steps work best to avoid overdriving the linkage.

Will this servo handle frequent high-load cycles?

Yes, the brushless design is intended to withstand heavy use better than brushed servos, but always check for wear on horns and linkages after intense sessions.
