i had using savox 1257TG for drift for 1 month now. i have setting the end point carefully so that the the extreme/maximum turning doesn't touch with any part and nothing blocks its movement, but still every turning of the servo produce sound (sounds like frequency distortion from the servo). If turn back neutral point the sound's away. What's the problem and does anyone experience this situation before?
Also, i would like to know what is the maximum life span of using this servo?? I drift almost everyday.
