I recently greased my 5955 with White Lithium grease. Then today i read on Hitec's website that this type of grease produces a gas the may put a film on the motor brushes. So now my servo motor will not stop running. The only thing i can get it to do is run in the opposite direction by turning the wheel on my radio, but once i release the wheel, the motor goes back to the other direction. When i do this with the gears/case installed, the servo will max out and stop spinning unless i turn the wheel. Would the film on the brushes cause the servo to do this? And if so what should i do to fix it.

Nevermind, i just lost the white plastic piece that works the centering mechanism. Now i need to find one.

What plastic piece are you referring to?
