Am building an old Don Lien 190. Have noticed that according to the plans the wing chord is 450mm. Measuring the finished wing, chord is 470mm.
My question is what CG to use? Plans say 125mm back from LE, but if you figure the difference in plans vs actual chord, the CG is 131cm back. Not much of a difference, but 131 is aft of rear CG shown on the plans.

did you gain the extra chord length forward of the main spar or rearward of it?

Are you including the wheel wells? I think they project forward of the leading edge at the root. That would not be included in the aerodynamic chord of the wing.

Well, looks like we brought this one back from the dead...
