The Higley Hamilton Heavy Hub arrived. I substituted a steel washer for the aluminum washer for the prop hub, then used two Higley heavy brass nuts and the Hamilton Heavy Hub. The engine and cowl have been moved forward about a quarter inch. (because of the repaired firewall). This get the CG to 122mm. I have flown the plane at 120mm which was ok, so this is close. With the big stabilizers and elevator, this should be ok. Total empty weight is 18.5 lbs. Hope to fly the plane today or tomorrow.
