Sullivan 1-1/8in Horns Left/Right RC Aircraft Control Horn - SUL557

The Sullivan SUL557 control horns are 1-1/8 inch RC aircraft control horns supplied in both left and right orientations, designed for use in fixed-wing RC plane linkage setups. Control horns are the small but critical fittings that connect your pushrods and clevises to the control surfaces — ailerons, elevator, and rudder — transferring servo movement into precise surface deflection. Sullivan is a well-established name in RC aircraft hardware, and the SUL557 offers a reliable option for builders fitting or replacing control horns during construction or repair.
