Title: My Wing - not LLog but similiar
Post by: frank williams on April 15, 2025, 06:46:03 PM

I have a wing build system that I have used successfully for several years.  Its not quite a Lincoln log wing, but similar, and better I think.  The wing is built on 1x2’s with the leading and trailing edges projected over the 1x2.  The wing parts are all indexed with notches that make the alignment of parts automatic, no need to build over plans.  The wing is sturdy with L beam spars capped with 1/16x1/4 spruce.  The airfoil is excellent and produces the best hourglass 3rd corner ever done.  I have .dxf files if you wish to cut your own.  Email me too large to publish here.

I am building one of Frank's wings.  It is GREAT!   With the cutouts/notches, it is super easy to put together.

 ..... without tips, just squared off, and 3x2 full span flaps ..... its about 680 in**2

choose your favorite cutter .... it requires about (10)  3x36x1/16 balsa .... I cut them into 18 in lengths for smaller cutters ....
