Hirobo HI0304036 Rudder Servo Plate for Lepton LEX Helicopters  [HI0304036]

Lepton LEX tail servo adapter

This Hirobo HI0304036 rudder servo plate serves as a direct-fit replacement for Lepton series LEX helicopters. It provides a stable metal platform for the tail servo to help keep servo position and link geometry consistent under operational loads.

Material and role: supplied as an anodised metal component, the plate reduces flex where the servo mounts to the tail tower. Its role is structural stability and repeatable geometry rather than altering servo performance or electronics.

Compatibility and checks: intended for Lepton models using standard micro tail servos and traditional linkage rods. Prior to final installation confirm hole alignment, check servo spline orientation, verify the servo horn and linkage travel without obstruction, and ensure the plate does not interfere with nearby frame parts.

Installation notes: attach the servo to the plate using the original screw locations or equivalent fasteners, tighten fasteners incrementally to prevent warping, and ensure the control horn sits square to the tail shaft at neutral. Minor trimming or tail gain adjustment may be required after swapping the plate because mechanical changes affect control feel.
