Dumper Rudder (80) technical overview

Offered for HIROBO helicopter ranges, this RC-scale tail rudder serves as a replacement control surface for Eagle, Freya, EX and SX models. The Dumper Rudder (80) is used to influence yaw and support tail stability during hover and manoeuvres.

The component is produced as a molded plastic part intended for easy exchange during scheduled maintenance or post-impact repair. It transmits servo motion into controlled tail movement and establishes a consistent reference for trim tuning.

Installation notes: the rudder secures to the tail assembly using the aircraft's original linkage and fasteners where compatible. Align the control horn and linkage with the servo at neutral before final tightening and confirm the rudder moves freely without binding. For tuning, apply measured adjustments to tail trim and servo endpoints, testing hover stability after each change.

Can this rudder be used across different HIROBO tail configurations?

It is compatible with Eagle, Freya, EX and SX families when the mounting points and horn position match the original part. Check your tail assembly dimensions to confirm interchangeability.

What material is used and is it suitable for routine replacement?

The rudder is molded plastic, chosen for low weight and ease of replacement. It is intended for routine service and should be replaced if it shows significant wear or damage.

Any best practices for control horn and linkage setup?

Set the servo to neutral, align the control horn so the rudder sits central, secure the linkage and confirm full free movement. Then refine trim and endpoint settings with incremental tests to achieve stable yaw control.
