Seba, for your Edge horizontals, are you using the SG planform (Root chord = 3.25",Tip chord = 1.625", sweep = 0.625", half span = 6.875") or are you using another?

Can you post the planform measurements (Root and tip length, sweep and span)?

It looks to be a linear taper so could we use the online simple MAC calculators (like this one: http://www.geistware.com/rcmodeling/cg_calc.htm) to get the distance from the leading edge of the horizontal for mounting the pivot for the v mount or is it too inaccurate a method?

Using the Super Gee planform, I got the following from the listed calculator:
Calculated Results
Mean Aerodynamic Chord (MAC) = 2.53" length tip to trailing edge

MAC distance from root chord (d) = 3.06"

25% MAC as measured from the root chord = 0.91"
30% MAC as measured from the root chord = 1.04"
35% MAC as measured from the root chord = 1.16"

Not sure if this applies to Seba's horizontal or not though
