The original Yokomo horn puts the servo link at a such big angle, which in my opinion makes the steering uneffective.
I am going to try a TLR aluminum horn for the 22. It seems to have a similar off set tot the OEM Yokomo plastic horn. I had to drill and tap it for the 3mm ball stud however. I also ordered a 20mm Kyosho turnbuckle from AMain I plan to use between the ball cups. The manual says to screw the cups together but I don't like the angle of the servo like that, I like th servo to point straight up for straight ahead wheels. I plan to add 5mm of a gap with the new turnbuckle and the cups.
