This Hirobo HI0412193 elevator torque lever is an RC-scale replacement part intended for the Sceadu SZ-G series, offering a direct swap for the elevator linkage assembly. The component carries the HPM marking from the original product name and is described here strictly as a helicopter model accessory for control-link adjustments.
Use this lever when you need to restore a worn linkage mount or refine elevator response during flight tuning. The lever acts as the mechanical interface between the servo output arm and the elevator control rod, so correct alignment and secure fasteners are essential for predictable tail pitch behavior.
Installation notes: verify fit with the Sceadu SZ-G tail assembly, inspect mating bores for wear, and use the original hardware torque values to avoid over-stressing the part. After installation, perform ground-range checks and a cautious hover test to confirm neutral positions and travel limits before full flight.
As a direct-fit accessory for Sceadu SZ-G helicopters, this Hirobo HI0412193 lever is intended for routine replacement and precision tuning of elevator linkage geometry, supporting controlled trim adjustments during setup and flight testing.
