Hi Ron,

My Az rotor is a ham type (pedigree unknown), but the elevation rotor is a simple Alliance U-110.  I think I paid something like $5.00 for a pair of them.  As you scan see in the pictures, it handles quite a lot, as long as the balance is kind of close.  If it matters, I chose to put a simple screw into the horizontal shaft where the Elevation rotor drives it, so it's not super stiff at that joint.  Gives the motor a little "give" when starting.
