What is the advantage of the upside down V tail? How does it work?

Well first it protects the prop. There is a coupling effect with the
rudder and roll. Right rudder will cause the aircraft to roll to the
right which is what we do with the controls. I still
think they use ailerons however.

Paul /Jim,

reduces drag over traditional T tail ie. less wetted area = less drag.
However, the upright V tail cause some wallowing in some aircraft - this is
not evident in the inverted V, apparantly. However I could be completely
wrong
but it sounds plausible.

BTW Paul in your article (which is very good) I understand most of it, so I
must
be paying some attention.
If I might add my '2 bobs' worth without offending !
1. Typo - line 5, P.8 "This consist" ie. They consist or This consists.
2. P.8 Last Paragraph - I just dont get it at all !?
Should that read " large radius must be used on the cowling" !?
Perhaps it's just me not understanding what your getting at !

Is this the paragraph from "How to Cool Your Wankel" ?

If an opening is at the bottom or edge of the firewall a large
radius must be used on the firewall just before the opening in
the cowl. This minimizes the energy loss of the high speed
cooling air exiting the cowling. This has been well known for at
least 70 years.
