What configuration options are available over S.Bus2?

Using an S.Bus2 compatible transmitter or interface you can set endpoints, direction, centering and other servo parameters to match your model setup.

Will the plastic gears hold up in heavy use?

Plastic gears are common in this size and perform well for most hobby use, but avoid shock loads and check for wear if used in high-stress applications.

Is the weight suitable for light sport models?

At 53g the servo is light enough for many sport and park scale models while still providing useful torque and speed.
