I'm just starting to look into EDF systems... and I haven't seen as nearly
as much info as standard props+motors.

What are popular motors for various amounts of thrust? What is an
ideal range of KV? Popular fan units? Does anyone make a fan unit
that has lower pitch-mph for higher static pressure? What is the
expected pitch-mph efficiency for EDF? Is there a handy pounds-of-
thrust vs wattage required estimation?
