Promptly delivered, retract works now.
One landing gear retract motor was intermittent since new in May 2017. The gear retract motor was easily replaced and now both landing gear legs retract. Vertigo sent out the part promptly.
I suggest a T-handle or palm drive for the tiny Phillips screw attaching the carbon fiber leg to the motor. It requires a very high twisting efforts to unseat so my jewelers / standard screw drivers slipped in my fingers. I used a 1/4" ratchet drive and socket bit but If I did this size screw often I would purchase an appropriate set of drivers.
