Guys,
As I am shopping for an UL and I am seeing many direct-drive and reduction-drive choices.
I'm hearing about B-Boxes - C-Boxes, etc.

If it's not too much trouble can someone give me the skinny on all this, and why I might
want or not want these features?

I'm just a Cessna guy here and trying to learn all I can before I choose a plane.
Thanks
John - Columbus Ohio
