I have a matrix buggy. Started out as RTR, now its at least an FRE. I have gotten into experimenting with new servos. During this process I noticed that my steering is tight, too tight, almost binding. If I manually operate the knuckles back and forth by hand it is too tight. I recently put new CNC steering knuckles on it. it SEEMS as though the little collars that sit in the hub carriers and the mounting hardware for the knuckles cause the knuckles to bind when tightened correctly. If I loosen the upper and lower mounting hardware for the steering knuckles it is much better but if that hardware is that loose it will most certainly fall out under the vibration of running.. Have any of you had this happen adn if so what can I do about it...? THANKS!
