How do I check if my receiver supports S.Bus2?

Refer to your receiver manual or product page; S.Bus2 compatibility is typically listed under protocol or features. Futaba receivers and compatible third party units often support it.

Are there recommended horns or linkages to use?

Use a horn size that provides the throw and mechanical advantage you need while avoiding excess stress on the plastic geartrain; metal horns are an option for higher loads.

What maintenance should I perform on the servo?

Inspect mounting bolts, linkage joints and check for play in the output spline regularly. Keep the unit free of dust and moisture to extend service life.
