If one motor is sufficient to power the pitch axis you can use this conversion kit to replace the already existing double pitch drive. In doing to so you will replace the two iPower GBM4006-150T motors with one iPower GBM4006-150T motor and one swivel joint.
Comparing the single pitch drive to the double pitch drive you will find that the former is characterized by a slightly lower weight and power consumption. However, this drive is only suitable for you if the camera you are using is perfectly balanced in relation to the center of gravity and the camera weight resembles that of a Sony Nex-5/7.
