RV 7 Rear spar Trim Detail

I have QB RV7 wings. There is a trim detail for the aft spar of the RV7 on DWG 38. I am trying to confirm this still needs to be done on a QB.

Thanks!

RV-7 QB Wing Rear Spar Trimming

It had to be done on my RV-7 QB wings. I completed this a few months ago.

I did it gradually to avoid initially removing too much material on the spar, cutting outside the lines at first, checking the fit and trimming more as necessary in a couple of iterations. This did require slipping the wings out of the fuselage a few times.

For my QB wings, it ended up at the dimensions shown on the plans.

Just finished the trim on my QB wings. Take it very slow. There isn't much extra material to allow still maintaining edge distance. I had to go slightly more than the template in order to get the sweep right, but it took 3 tries of wings on/off to get it right.
