I am new here and I have been researching this whole site trying to learn all I can. I used to have a Benson but sold it a few years back kicking myself ever since.
What I would like to know is what is the difference between a two place and a single place rotor head? say like a Parsons and a Benson? and what would be the difference in hub bars? I got a million questions just wanting to spill out but maybe later. Thanks
 
Dan,

Typically two things. The heavier machines usually have double bearings, although some singles do, too. The teeter towers are taller because there is more undersling with longer blades and greater weight.
