Mick,
The GoTo is made by ME
I used the Motor assemblies and hand controller from a LXD-75 Mount. I modified the brackets to accomodate the motors and boards. I also custom fabbed a panel to hold the original LXD-75 Power panel. I would rate the conversion a 7 on a scale of 1-10.

Any more questions let me know
