Thanks Art,

This exercise has been a bit enlightening. Neither of the paper plans for the wings are straight. The distances between the ribs are neither consistent on the same plan nor between the plans. Then Ilooked at the manual and this particular kit uses a laser cut 1-piece main spar shear web and same for the rear spar shear web. Next time (uh huh) I will make sure that things are square irrespective of whether they match the plans or not.

Sometimes brain damage just happens ....

Cheers,
