DD 1 Notice there is a "right" and a "left" torque rod Twist
each rod to match the sketch above (to allow the correct flap

D D 2 Starting 3/8 from the root of one wing panel, draw a
line on the back edge of the sub TE is 5/32 away from the
bottom edge of the sub TE and 2-5/8" long Draw a line using the

D D 3 Cut a 5/32 square strip out of the sub TE using the
lines you just drew Test fit the torque rod into this groove to make
sure the groove is long and deep enough The torque rod nylon
bearing should be flush with both the back and the bottom edge
of the sub TE You can make the slot longer or deeper if needed
to allow the torque rod to operate freely

with coarse sandpaper Apply a small amount of vaseline around
the ends of the bearing to keep glue from seeping in and glue it
in place Make sure the bearing is centered on the torque rod and
