Re: Re: F3J Flight Matrix Calculations
Yes maybe. It's an opportunity to shape the event. As a rulebook event it would possibly gain participants in new venues.
It's a great event, and part of evolution, which we need. Rob Glover On Sep 29, 2011, at 19:55, "Jim Monaco" <jimsoars@earthlink.net> wrote: > No I haven’t Rob – but that should be possible.
