I started a Great Planes Rapture 40 yesterday. I am to the point of gluing in the shear webs. The plans show the webs on the front of the spar. The way I have everything pinned down it would be easier to putthem on the back of the spar. It seems that either location should be fine but I thought I'd ask.

It will be fine. different kits have them on either the front, back, or centeered between the spars.

Yep, you'll be fine with them on the back of the spar.

My vote is the back of the spars as it is easier and does not require very precise cuts as the between the spar type shear webs. There is a significantly more glue contact surface when placing them on the front or back of the spars as well. Be sure to run the grain vertically. Running the grain horizontally will cause the webs to spit along the grain just as soon as there is a significant load placed upon the wing panel...
