It offers an approximate 30% improvement in response over standard digital servos, uses similar current to brushed digital types, and the brushless motor construction results in about five times the expected operational life.

Why the BLS257 stands out

Brushless Motor: Longer service life and stable performance during heavy use.
Fast Response: Around 30% quicker response to assist in precise manoeuvres.
Efficient Power Use: Comparable draw to brushed digital servos for straightforward power planning.

Will the BLS257 work with my tail servo saver?

It will, provided the saver geometry and horn fitment match; verify horn size and linkage length to ensure correct throw and neutral alignment.

Is the BLS257 waterproof?

This unit is not specified as waterproof. Keep it dry and protected from moisture to preserve motor and electronics life.

How should I check servo centring?

Power the servo at neutral, mount the horn in the neutral position and confirm with a servo tester or transmitter subtrim for precise centring before final assembly.

Can I upgrade linkages for harsher flying styles?

Yes, consider hardened or lighter-weight linkages depending on whether you need extra strength or reduced inertia for faster response.
