Revo steering center problem

[Childresshunt]

I have a revo 5309 running the two steering servo setup and its running ppp servos. steering is great servos move tires on ground setting still no problem but when your running it the center is constantly messing up. Would a glitch buster fix this issue

had similar problem after i bought a cheap radio and receivers .the steering would never find center making it hard to control .At first i was thinking defective servo however it did it on all 3 cars (the radio was able to be used on up to 10 cars) i even replaced the steering servo on one of my cars and had the same result
