Rêve D aluminium adjustable servo horn

This lightweight and super rigid split servo horn from Rêve D can adjust the distance from the centre of the servo horn to the rod end ball steplessly from 19mm to 23mm with just one screw. It is possible to instantly adjust the lever ratio according to the servo speed and counter timing. There are two types of spline fitting, 25T (for servos such as Futaba and Rêve D) and 23T (for servos such as Sanwa and KO) so that you can choose according to the servo manufacturer you are using. A secure clamp method is used for mounting the horn and can be firmly fixed.
