The controller came with its own stepper motor in the kit, but the scanner motor was geared down which allowed the motor to run faster avoiding a jerking image. The kit has been dropped from their latest catalogue, but some branches still have stock. Ocean Controls have the K179 kit which is a stand alone which will work up to 35volts. I was using a 9v transistor radio battery, but have ordered an 11.1 volt rechargeable LiPo. The little battery was able to pull my 40 kg 8" Skywatcher collapsible dob quite easily. As long as you find the centre of gravity of the scope and its mount and design the bearing runner radii to suit, there is very little load on the motor geared for minimum speed and maximum torque. Pix wil follow but the thing is in bits at the moment while I fool around with the design.
