June 8, 2024Application(s): Hi IV had this servo for about 15 years Iv only just got back into racing and bought a 1/10 touring car and thought ill use my 2123 servo It works perfectly but I can't find any servo horns that fit Iv tried a lot of different sizes and nothing fits I bought a 25t servo saver but still to small.
