This thread is about canards, but it might lend some insight into what happens as the airplane layout changes.
The two pictures show that max performance occurs with roughly 30-35% tail area(as a % to total area).
I've only tried that big a tail on one plane, and it was a profile carrier.

Phil,

according to Fraser´s article, the tailplane size can be chosen freely, adapting the CG.
Equation (13) gives the location of the neutral point. The CG should be 8% of x12 ahead of that neutral point.

It works, even for tandem airplanes.

Regards,

Wolfgang.
