Does this servo cope with high steering loads?

Yes. The torque ratings and dual ball bearings mean it handles heavy steering demands typical in 1/8 scale competition vehicles.

Which battery types give the best results?

Use 6.0 to 7.4V supplies. A 2S LiPo or 7.4V regulated feed will maximise speed and torque, while quality Ni-MH packs also work within the servo's range.

Are replacement horns and gears available?

Replacement servo horns and compatible gear kits are commonly available; match the standard size and spline pattern when selecting spares.

How should I set end points and centring?

Set endpoints via your transmitter to avoid overstrain, and centre the servo horn mechanically before final trimming to ensure accurate neutral steering.

What routine checks help extend lifespan?

Regularly inspect mounting screws, wiring and the connector, keep the horn and linkage free from play, and replace the horn if stripped to maintain performance.
