I'm curious if there are any NACA/NASA/other reports out there regarding the inverted-V style of ventral fin vs a single vertically-oriented ventral fin... anybody ever see one?  As mentioned countless times here, anecdotal evidence ("He developed it for the garrett conversion and said it was quite effective") is nice but a well-documented aerodynamic test series would be better.  Not casting aspersions or throwing stones, just curious.

Berni,
I have not converted to a turbine. However, you can buy a ventral fin
kit from Mike Custard at www.advancedaviationinc.com . He developed it for
the garrett conversion and said it was quite effective.
