That sounds like a Chuck Cunningham article. He wrote the same article half a dozen times. Pretty basic stuff from the 60's or 70's. His numbers were something like:

a wing with an aspect ratio of 5 or 6 to 1

Ailerons about 6% of the wing area

Fuselage length about 75% of the wingspan

Horizontal tail of 22-25% of the wing
Elevator about 20% of the horizontal

Vertical tail about a third the area of the horizontal
Rudder about 30% of the vertical

Balance at about 25%
