Lepton LEX Tail Servo Plate Upgrade HI0304036 - Hirobo  [HI0304036]

Upgrade plate for Lepton LEX tail servo

The Hirobo HI0304036 rudder servo plate is an intended replacement part for Lepton LEX helicopters, offering a more rigid mounting point for the tail servo. The improved platform helps preserve linkage alignment under load so tail inputs remain predictable.

Material and role: this metal plate is provided to limit flex at the servo attachment and to keep mounting geometry repeatable. It is a mechanical upgrade and does not modify servo electronics or output characteristics.

Compatibility and checks: fits Lepton family models that accept standard micro tail servos and conventional linkage rods. Before securing everything permanently, verify holes line up, confirm correct spline orientation, make sure the servo horn moves freely through its travel, and ensure the plate clears surrounding components.

Installation notes: mount the servo to the plate using the designated mounting points or similar fasteners, progressively tighten screws to avoid bending the plate, and set the control horn square to the tail shaft at neutral. You may need to tweak tail centring or gain slightly after installation because the new mount can change mechanical geometry.
