23% back from the leading edge a few inches out from the wing root.
Just a ball-parky figure.
Here is a thread on what I believe is the same plans (by Bert Baker). You might want to message TLH101 and see if he still has the plans.

Here is a caculator http://adamone.rchomepage.com/cg_calc.htm
Here is another where you can enter where on the mean aerodynamic cord you want the CG. For a test flight I would start at 25%. http://www.nasascale.org/howtos/cg-calculator.htm

RE: CG on P-39
I've only built one model of the P-39 and found that you wanted to error on the side of being nose heavy as this platform seemed to tip stall at the drop of a hat.
