RE: FASST FLIERS UNITE
My gosh, is the sky falling again?
All you need to do is have someone bring one (1) new Rx that has never been bound to this "meeting" and see if YOUR Tx controls it. If it does you have a ZGUID Tx. If it doesn't you are fine. You don't need to operate a bunch of TX's at the same time or place to test. And if you keep a ZGUID Rx available at the field (or other place) then you can test WHENEVER you feel the need or when an untested unit shows up.
