Progress on the extended wings

7 posts in this topic

Posted

Jack and I have been making some good progress on my new extended wings.  Lift struts are extended and clecoed for now until I am sure everything fits.  Wings extended and inserts, lift strut brackets in place, glued and riveted and ribs glued.  Will work on wing tips with a few teaks next.

Thanks guys, it feels good to see them finally taking shape.  It will be good to compare performance against my stock HH wings when I get them done so others will know if it is worth the effort.

Jack and I accomplished a major milestone last weekend; We hung the new extended wings on the Avid+ and got the mounting holes all drilled!!! (even though it looks like we did nothing with the old wing back on the plane and new ones back on the sawhorses.)  The extended lift struts fit great and the dihedral checked out at about 2 degrees for both wings.  The jury struts still fit good with only a bit of shortening required at the spar bracket ends.  One thing I had not counted on in reducing the wing washout to 3/4" was that the tanks have the washout built into them for the standard 2" washout; but after a bit of head scratching I was able to take most of that out pretty easily with some adjustment to the rear lift strut lengths and since I had clecoed them together and not welded them just in case there needed to be some adjustments made, it was an easy fix.  At 3/4" washout the angle between the spars is 1.2 degrees; at 2" washout the angle is 3.45 degrees.  I was able to get the washout angle at the extended spar tips to 1.7 degrees so I am pretty satisfied with that! 

One tool that proved very useful for changing and positioning the wings was a sheet rock jack; I highly recommend it to those don't wing removal and replacement.

Here's the proof!

How long are those wings Randy?  Same as Catalina or Magnum?   I will be interested in hearing how 2 degrees of dihedral makes it fly compared to the 1 degree that Kitfox (and Avid?) uses.  The Birddog L-19 had about 3.5 degrees of dihedral if I remember right - more than C-170.  Good post.   EDMO
