Hi gang
Question is: how is critical for speed models ( like F5D/F5B ) vertical tail volume coeff. over 0,02? Calculated value now is 0,027. Any suggestion welcome...
Regards
V.

If you want to reduce the drag with area, you could reduce the tail volume coeff. down to 0.02 and get by with handling quality. Otherwise, the tail volume coeff. of 0.027 is just fine.

Thanks, Ollie
I thinking about turn behavior, drag is not problem on this project...
