A solid choice when upgrading a helicopter tail setup, the Futaba BLS251 balances precision, cooling efficiency, and rugged gear construction for dependable field performance.

Does the BLS251 require special gyro settings?

You should follow the gyro manufacturer's setup procedure for GY601 or GY611 and adjust gain to match the BLS251 response during low-risk flight testing.

Can the servo be used with different linkages?

Yes, provided the linkages are correctly sized and free of play. Secure, tight linkages help exploit the servo's precision and protect the metal gears.

What checks should I perform before flying?

Verify neutral alignment, confirm endpoint settings, test full travel on the ground, and validate gyro gain before attempting normal or aggressive flight routines.
