Pair of Falcon 500 v1 motors, purchased fall 2019, put in a mechanism which got a few hours of practice for a competition Spring 2020 (actual games were cancelled). Never had further use; in storage since then. These 2 have modified 8mm diam., 30mm long shafts, with flats for 2 set screws, to secure gear or pulley. Some scratches on case ends, otherwise like new. Bench tested to full speed -- all normal. Sold AS IS, as pair only.
More detailed mechanical history available on request.
