The best answer I've heard is that they won't fly with without them. Why? Good question! I guess it depends on who you ask.
with an eye towards the answer of Heiner also:

A bit late but never too late:
I heard from Alphons Gabsch that he did some experiments in the past with smoke etc. lead through the ducted fans. It appeared that the smoke then coming out of the exhaust, was going underneath the wing, sucked back into the air-intake, creating all kinds of turbulence.

The solution seems to be to place a stand in front of the opening. In the HoIV of CPDUDE, I am building one 1/2 cm thick, 1 cm depth, in the opening-middle of the intake.
It then creates a kind of turbulence, that even make the internal rudders obsolete.

Peter,

You mean my Ho IX? The one that Uwe designed?? Please post pictures of what you are planning...or at least send the pictures to me. We don't want to let everyone else know what you are up to.

Brian
