Does the servo fit common 450 class mounts?

The dimensions are compact and compatible with many 450-class helicopter mounts; check the specifications section for exact size details to confirm fitment.

What routine maintenance keeps the servo reliable?

Inspect linkages and mounting screws regularly, avoid water exposure, and replace horns if damaged. The metal gears and bearings minimise service needs but do benefit from periodic checks.
