Not sure exactly how the DE does the 1/8" spar web, if it is 1 piece or multiple. The joints of the Legal Eagle are just butt joined centered over a 3/4" x 3/4" intercostal (the vertical "spacers" in the spar) every 3rd main rib. Where there are no joints in the spar, yes, they are 1/4" x 3/4".....ALL rib spacings should be 15" (PLUS the 1-3/4" at the root and at the tip) OR that's they way they are on the LEU... .. giving a total wing panel length of 139" out to out. NOTE: the 1-3/4" is center to center of the outer two ribs each end (root & tip)... or 2" out to center.THUS you have: 2" + (9 x 15") + 2" = 139" total wing panel length.
Thanks for the info on making sure there is enough material left after the taper and bevel. I made a rough drawing and measured, and you are right. You need to add about 7/32" to maintain the 1/4" at the tip.I guess that leads to the question: What is the purpose of the taper on the last 46" of the spar caps? Is it for weight? Does it change the flexibility at the tips?Leonard, can you answer why there is a taper on the ends of the spar caps?Thanks
Hi Steve,The taper is for lightnes and is onthe bottom of the top spar cap and the top of the bottom spar cap. There should be plenty of room for the angle cut as the tip is 1/4" thick.
