From T-Works comes this range of clamping style two ended servo horns. Made from 7075-T6 aluminium, each horn has been black anodised and has machined chamfers on the edges. They come in two versions and with two different spline types. There is the standard flat version and one that is 1.5mm taller on one end and there is the 23 and 25 tooth spline version of each. The screw down clamp on the collar ensures that servo horn doesn’t slip under heavy work loads. The horns come complete with mounting hardware as well as bushings for the mounting holes.
