This Futaba FU1K17201 replacement is an RC-scale servo horn supplied as one piece and shipped without packing or mounting screws. It uses the TYPE-L small-circle arrangement named in Futaba documentation to match the mounting pattern on the listed Futaba servos, keeping the installation footprint compact for tight linkages and confined servo bays.
The part is intended for direct fit to the listed servo models; confirm spline count and bore compatibility on your specific servo before installation. Typical uses include steering and throttle or brake linkages on scale electric and nitro models where small throw adjustments and consistent geometry are required.
Installation notes: remove power from the system before swapping horns, centre the servo horn with the servo at neutral, seat the horn fully onto the spline, and secure with the appropriate screw type supplied with your servo or a hardware kit. After mounting, check end-to-end travel and adjust subtrim to avoid binding. Treat this component as a scale RC accessory during setup and tuning.
