The following information came from "Unofficial Guide for building the Hot Spot" PDF file I received from Bob W.

Technical information.

from the vertical fin. Place a ruler along the wing leading edge and butted up against the
vertical fin. Measure down the leading edge from the vertical fin and make marks at 7
and 7 1/2 inches. Lift the plane by placing your finger at each location and balance. At 7
inches makes a easy flying plane and 7 1/2 livens it up a little. Make sure the plane is
also balanced from side to side.
