I'm using a semi ducted setup:

I've got a duct with a vacuum formed intake lip midway into the fuse.
The duct intake lip has a 5mm radius.
The intake tube is heavy photo paper and the efflux cone is cut transparency sheet.

Lining the walls of the fuse and also acting as structural supports for the top fuse is a funnel of sorts. Time will tell if this setup works, but it allowed me to quickly and painlessly duct this plane.

Pic One is the vacformed intake ring
Pic Two is the thrust cone
Pic Three shows the psuedo ducting
