Ideal for modelers replacing or upgrading servos on small helicopters and light aircraft, the Savox SH-0254 gives compact, reliable control.

Which roles suit the Savox SH-0254 on model aircraft?

Use it for CCPM swash servos on 450 class helis and for primary control surfaces on park flyer planes where a small, torquey servo is required.

How should I check for wear on the gears?

Inspect gear teeth for rough edges or play and ensure the output horn runs true; replace or service the servo if any abnormal movement appears under load.

Any tips for installation and setup?

Ensure correct spline alignment and use the correct horn; centre the servo with your transmitter and confirm travel limits before first flight to avoid binding.
