HPI Savage Servo Issue
 

Ok so I'm having an issue with the throttle servo on my Savage 21, as soon as I turn on the power to it the servo it opens the throttle about 3/4 of the way...if you turn the power back off it will go back to the idle position or if you turn on the radio and push the trigger to engage the brake it will also return to the idle position. Anyone else ever have this issue or have any idea what might be wrong? They are the stock HPI servos.
