This Hirobo torque lever is listed as HI0304041 and is presented as a direct replacement part for models identified as LEPTON LEX SWM in the product name. It functions as the tail torque lever component used in RC-scale helicopters to transfer control input and help manage tail torque behavior.
Installation notes: remove the existing lever and install the replacement in the same orientation, verify correct seating on the shaft and check linkage alignment before flight. Perform a bench check of tail control movement to confirm free travel and secure fixing.
Tuning role: the torque lever affects tail control geometry and response, so accurate fit and alignment are important for predictable tail behaviour; inspect connections and hardware after initial flights and during routine maintenance.
