The Futaba FU1K17201 is an RC-scale replacement horn sold as a single unit and provided without mounting screws or packaging. The TYPE-L small-circle pattern referenced in Futaba materials lines up with the mounting layout of the specified Futaba servo models, allowing a compact installation in confined servo bays.
This item is made for direct fitment to the listed models; confirm spline count and bore size on your servo before installation. Common applications include precise steering and throttle/brake linkages on scale electric and nitro vehicles where fine adjustments and reliable geometry are important.
Fitting advice: isolate power before removing or fitting horns, centre the servo at neutral, fully engage the horn on the spline, and fasten with the correct screw from your servo or a suitable hardware set. After fitting, check full travel and subtrim settings to avoid any binding. Consider this a precision accessory for scale RC setups.
