Questair Venture vertical tail?

[addaon]

Anyone have vertical tail volume coefficient or vertical tail area for the Questair Venture?

Vertical;
Area = 9sqft
Span = 4.13ft
Arm = 7.76ft (just 28% of span!!)
Coefficient = 0.036

And the horizontal for the sake of it
Area = 12.56
span = 8.66
Arm = 7.91 (3.1x MAC)
Coefficient = 0.557

Source is a 3-view from a NACA report that was then scaled to the correct dimensions then measured. So the above are likely off by a bit but should be ballpark.
