5. Working with the left wing first, make a mark on the
flap LE directly behind the side opposite the hole in each
servo bay cover. This is the side the pushrod will be on.
❏ ❏
6. Hold a small control horn over the mark you made
with the pushrod holes directly over the hinge line. Drill two
3/8" [9.5mm] deep holes using a 1/16" [1.6mm] drill bit.
❏ ❏
7. Install the control horn using two #2 x 3/8" [9.5mm]
sheetmetal screws.
❏ ❏
8. Prepare a 6" [152mm] pushrod the same way you
prepared the aileron servos using one nylon clevis and a
silicone clevis retainer.
❏ ❏
9. Attach the clevis to the outermost hole in the flap
control horn. Extend the pushrod forward and mark the point
that you will make the first 90° bend.
❏ ❏
10. Bend the pushrod 90°. Insert the bent portion
under the hump of the nylon strap. Make a mark at the point
you will make the second 90° bend.
❏ ❏
11. Remove the pushrod and make the second 90°
bend so that it is vertical as shown.
❏ ❏
12. Remove the nylon strap and reinstall the pushrod.
Make any adjustments to the length of the pushrod by
tightening or loosening the clevis until the flap is set in the
retracted position.
