This is a 25T aluminum clamping throttle servo horn from Tekno RC. Eliminate the possibility of your servo horn stripping, coming off, or your brake and throttle going out of adjustment and causing a runaway. Not only is this laser-etched servo horn made from aluminum and inherently much less likely to strip or flex, but it also clamps and grips the servo output shaft tightly to help prevent it from falling off or losing adjustment. In addition, this new servo horn is designed with a slight angle between the brake and throttle lever, which provides a more consistent braking force through the servo’s rotation. The aluminum horn is a direct replacement for the stock composite horn (TKR9392), uses the same 5x8x2.5mm bearings and brake linkage, and is for use on the 2.0 series of nitro vehicles.
