There is a lot of weight on the trailing edge once you rotate flat.



That means the hinge-point for the wing-saddle is incorrectly

positioned. If the rigging aid is properly designed, there should

be almost no rotation force once the wing is ~level.

Which unit is this one ?


Sorry, conflated statements. I was purely speaking to the balance of the Duo wing when manually assembling the glider. The CG is aft of the spar a bit. I also have to make sure when you have extra helpers that they don't lift on the leading edge or on the leading edge side of the handle at the tip. Nothing like trying to manage the root of the wing and then have another 20lbs of torque applied.

The reason I would buy the XC version of the wing rigger was in order to ensure proper balance on the rigger. It doesn't meet your requirement for being able to easily adjust the height without going under the wing or crouching.
