Camera Gimbal jerks up and down

I am using a Skyrover Mini Camera Gimbal that has two Hitec HS-5245MG servos plugged into the Naza F1 and F2 on my F550. It was working fine for a few weeks but now it jerks up and down repeatably. When on the ground in idle it is stable but as soon as I lift off it starts going up and down, almost its full length of tilt. Anyone know what might be causing this?
