I looking for some information on the spar cross section on a RV7 and RV9. I'm not trying to build one, I just looking for some information to make some comparisons. I have a zenith 601xl and as some of you may know the wings have been coming off in flight. Will someone please share some dimensions on the cross section of the spar for a 7 and 9. I'm specifically interested in the height of the spar and the number and size of the upper and lower spar caps as well as rivet spacing and size. A picture would also be appreciated
Thanks,
Mike
