Allen, I only added 5 in total. "I added right at five inches (the space between the 3rd and 4th rib on both sides is +-2.5 inches). I made a copy of both wing sections and taped the third rib on one down over the forth rib on the other." I added one rib on both side and placed it at the location of the #4 rib (pushing the #4 rib out). That added the space of aprox. 2.5 in to each panel. That is about the same as what you added I think. five inches is about 12.5 cm. I left the tale and boom the same. In fact I change the wings on the same fuse from the short to the long depending on the day, wind, and lift. I used a little less dihedral than the plans called for by mistake. I did not have the wing tips set high enough when I glued the halfs together. --- In BugHLG@y..., Allan Wright <aew@m...> wrote: > > I did it with out recalculation.
