Sabre XLT Airfoil Templates
JAN 2014
If you read Mike Oser's Lancer blog referenced above you will know that the specially designed airfoils are a major part of the Lancer's performance. I tried to follow exactly the airfoil contours when building the Sabre wings.
Mike provided full size CAD drawings printable on 8.5 x 11" tiled paper.
Tiled airfoil patterns cut and taped together, then cut to rough shape, and sprayed with removable spray mount adhesive
Patterns laminated to 1/4" birch plywood blanks
Patterns cut out on band saw
Templates sanded smooth with sanding bar
Hot wire run off guides installed into the leading and trailing edges of the templates.
1/16" holes were drilled into trailing edge and into top and bottom of leading edges, parallel to the center line of the templates.
Then pieces of 1/16" music wire are inserted and thin CA glued into the holes leaving about 2-3" sticking out.
