I did just like the manual says - I put a piece of tape under the top wing on each side of the cabane, 5 1/4'' back from the LE. Then, with my fingers centered on the edge of the tape, I lifted it up and she sat perfectly level (Tank Empty).
Mike,
Jack up the tail of the plane until it sits level. Tie a nut onto a piece of string and drape it over the leading edge of the top wing, and allow the nut to nearly touch the table surface. Now tie a nut to the other end of the string and drape it over the trailing edge of both wings, allowing it to nearly touch the table. What is the distance on the table between these 2 nuts? Plan on balancing the Waco at about 28 to 30% of the Mean Average Chord, which is the measurement that you made.
