Yes Dick, that is the leading edge of the stab, I am raising it 1/4'' which will make it 2 degees positive. Acording to what I have read, having positive in the stab along with positive in the wing provides longitudinal stability for the airplane, (sometimes refered to as longitudinal dihedral), which will be a plus.
The airplane is NOT nose heavy, that is the first consideration, I had to add 1 1/4 lbs of lead and it is ballanced perfectly!
balance at about 25% of chord and adjust stab for minimum elevator trim at desired cruise speed. and -rig both wings as closely as possible to same true operating angles
