Anyone know the leveling datum for the Duster? Plans indicate to weigh once the bottom of the wing is level.

The Duster has a flat bottom airfoil, place level with top against the bottom rear of center wing with bubble sticking out on the rear side. Raise tail till you get bubble centered.

Thanks, that is what we did. The glider seems very tail heavy (195 lb min pilot weight). I guess that is somewhat standard (tail heavy) from what I hear.
