Wing-support for Duo one-person assembly

It's heavy, but mostly it is awkward.


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 ?


Then for the person at the tip, the height is very high given the dihedral.
When Julie and I rig, the tip is at about shoulder height for her.

I have similar issues with the DG-1000.
Mark Mocho where are you? Are you listening?

What brand rigging aid are you currently using ?

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.

Hi!

Enstroj makes what you are looking for,

I have used this rigging aid and it great.

We've used an Udo rigger that was made for an ASW-20 on our DG-505 Orion quite successfully simply by making the trailing edge clamp longer to deal with the greater chord. I've got one for my 15b and like it better than the others I've seen. I actually prefer the mechanical jack to the gas spring setup on some riggers. I think what really makes the Udos work well though is how good a job he did making the wing saddle - very substantial and fits nice and snug to the contour of the wing.
