Default Information on CG for Vern Zundel design -1911 Deperdussin

Dear builders, I am currently scratch building the 1911 Deperdussin designed by Vern Zundel in 1970. The CG position was not indicated in the plans. Does anyone know where is the recommended CG position?

I tried to email Vern but his email address is no longer valid.

Many thanks and best regards

That plane has a constant chord wing which means that the Mean Aerodynamic Chord of the wing is the chord. Put the CG at 30% of the chord measured from the leading edge of the wing for a safe first flight. Dan.
