I have a team asociated 8.0 mgt monster truck(nitro). The steering servo needs to be replaced.The Original unit(s2008MG) is $125 . I'm wondering if I'm able to swap in an equivalent unit(like a s1903MG,only $10)or is the steering servo that different from other servos? Any info would be helpful. I'm going to call "Team Asociated"and ask them too.
