Accurate tail management with the Futaba BLS251

The Futaba BLS251 Brushless Rudder Servo is designed for helicopter pilots who prioritise precise yaw control. It works exclusively with Futaba GY601 and GY611 gyros. The brushless motor lowers operating temperature and extends overall lifespan versus brushed alternatives.

Performance highlights for rotorheads

Brushless Motor: Lower heat output and improved longevity under continuous operation.
Samarium Cobalt Magnets: Deliver stable magnetic performance for consistent response.
Dual Ball Bearings: Smooth bearing support reduces friction and sharpens response.
Metal Gear Construction: Strong gear set built to withstand heavy tail loads.

A reliable option for upgrading helicopter tail systems, the Futaba BLS251 combines steady performance with rugged gearing for long sessions at the field.

Can I use the BLS251 on other RC models?

It is intended for helicopter rudder duties and is matched to Futaba GY601 and GY611 gyros; other applications may require different fittings or adapters.

Do I need a special servo saver with this unit?

Using a properly rated servo saver or linkage appropriate for metal-geared servos helps protect the gear train from sudden shocks.

What installation tips help get the best response?

Set up neutral and end points with a high-precision transmitter, secure linkages to avoid slop, and validate gyro settings with small throws before full-power checks.
