501F USERS GROUP

The 501F Users Group dodged the Covid-19 bullet last year, completing its 2020 conference just days before the pandemic forced the cancellation of in-person industry meetings. This year’s conference, which began February 15, was the organization’s first virtual event and included content also of interest to owner/operators of 501G and H frames, plus the V engines. Users responsible for all four frames were encouraged to participate.

What follows is a summary of 501F content broadcast during seven days over a two-week period. Sessions began at 10 a.m. Eastern all days and concluded by 4:30. Visit the 501F Users Group’s website (https://forum.501fusers.org) to access presentations made available to the organization’s membership.
