Eagle/Freya/EX/SX Tail Rudder Replacement - HIROBO HRB-0404744  [HRB-0404744]

Dumper Rudder (80) overview for RC helicopters

This RC-scale tail rudder is supplied as a common replacement for HIROBO helicopter families. The Dumper Rudder (80) functions as the tail control surface used to influence yaw and maintain tail stability on compatible Eagle, Freya, EX and SX models.

Molded plastic construction makes the component straightforward to swap during routine maintenance or after impact damage. It converts servo inputs into directional tail movement while offering a predictable reference for trim adjustments.

Installation notes: the rudder fits to the helicopter tail assembly using the existing linkage and fasteners on supported airframes. Align the control horn and linkage with neutral servo output before final tightening, then verify a free range of motion to avoid binding. For tuning, make small changes to tail trim and servo endpoints; test hover performance after each incremental adjustment.
