ok so i ordered the direct drive from clermont and put it in and everthing, then the clip that help the gear in place came out so i had to retake it apart and put it back in, then i go out to drive it and the servos are being weird, when i stop sometimes the throttle doesnt want to go, i have to turn the wheels to get the throttle to move, then i took it inside and when i would turn the wheels the throttle servo would twitch and stuff. does anybody know what this would be, do i have to upgrade the servos or what.
