Install The Radio System - GREAT PLANES Ju-87 Stuka Instruction Manual

17. Attach a 6" servo extension to the flap servo. Apply
tape or a piece of heat shrink tubing to the connection to be
sure that the extension cannot come unplugged from the
servo wire. Remove the tape from the string inside of the flap
servo bay. Tie the string to the end of the flap servo
extension. Then pull the servo lead through the wing from
the end of the string at the top of the wing center-section.
Leave the string attached to the servo lead until you have
completed the servo installation instructions.
18. Place the flap servo onto the servo mount in the
wing. Drill a 1/16" [1.5mm] pilot hole through each of the
servo mounting holes and into the wing. After drilling the
holes, screw the servo in place with the hardware provided
by the radio manufacturer.
19. Center the servo and then install a servo arm onto
the servo. Use a felt-tip marker to draw a reference line from
the servo arm to the flap.
20. Install a small nylon control horn to the flap the
same way you installed the aileron control horns.
21. Locate one of the 2-56 x 6" [152mm] wire pushrods.
Install a nylon clevis and clevis retainer onto the threaded
end of the wire. The clevis should be screwed onto the wire
approximately 25 turns. Snap the clevis onto the control
horn. Be sure the flap is in the neutral position. Then make
a mark on the pushrod wire at the point that it is over the
hole in the servo horn. Important: Be sure that the servo
has remained centered as you have handled the servo. If it
has moved, repeat the centering procedure before marking
the wire.
22. On the mark on the wire make a 90° bend. Cut the
excess wire off 1/2" [13mm] above the bend.

23. Enlarge the hole in the servo arm to 1/8", slide the
wire into the hole and attach a nylon FasLink.
24. Repeat steps 16 to 23 for the flap in the left wing.
