MOUNT THE CEDAR LONGERONS USING A STRAIGHT BAR

NOTE:I BUILT MY PROTOTYPE TO RESEMBLE THE FULL-SIZE ASK 13 I-PLOQ IN THE ABOVE PHOTO,

RESTORED IN ITALY.THIS GLIDER HAS THE COCKPIT AREA COMPLETELY COVERED WITH PLYWOOD.

I HAVE CHOSEN THIS VERSION TO HAVE A BETTER GRIP DURING TRANSPORTATION,BUT AFTER SOME TESTS, I NOW BELIEVE THAT THE ORIGINAL VERSION WITH THE PLYWOOD ONLY ON THE NOSE PORTION SHOULD BE BETTER.

SEE DRAWING AND NOTES TO PAGE 62, 86 AND 94.

THE PICTURES ARE OF THE PROTOTYPE, PLEASE NOTE WE MADE SOME IMPROVEMENTS IN THE PRODUCTION VERSION.
