6. Hold the retract in the wing. Using the mounting
holes as a guide, drill 7/64" [2.8mm] pilot holes into
the retract rails.
Caution:
Do not inadvertently drill
into the electric actuator when you get to the middle
hole. Mount the retracts with fi ve #6 x 3/4" [19.1mm]
sheet metal screws, one in each corner and one in the
middle as shown. Use one #6 x 1/2" [12.7mm] sheet
metal screw in the hole over the electric actuator.
❏
7. Remove the six screws and retract and apply a
couple of drops of thin CA in the holes. Attach a 12"
Actuator Extension to the retract. If installing pneumatic
retracts, attach the airline to the retracts.
❏
8. Connect the actuator extension or air lines to the
string in the retract bay. Guide the extension or air lines
through the front of the retract bay, through the fl ap
bay and out the hole in the top of the wing. Also pull
the aileron servo lead out the hole. Tape the actuator
extension or air lines and aileron servo extension to
the top of the wing. Remount the retract in the wing.
❏ ❏
9. Set the retract cover over the retract and drill
a 1/16" [1.6mm] pilot hole using the holes in the cover
as a guide.
❏ ❏
10. Mount the retract cover to the wing with fi ve
#2 x 3/8" [9.5mm] fl at head sheet metal screws.

11. Cut two of the landing gear door drill guides
from the back of the manual. Place the drill guides
in the rectangle recesses of the landing gear door.
Place the landing gear door on a piece of scrap wood
and drill a 1/8" [3.2mm] hole through the door at the
marked hole location.
❏ ❏
12. Adjust the position of the two landing gear
door mounts so that they align with the fl ats on the
landing gear door when the door is positioned in the
landing gear opening.
❏ ❏
13. Install a #4 fl at washer on 4-40 x 3/8" [9.5mm]
machine screw. Insert the machine screw through
one of the holes in the gear door and thread it into the
landing gear door mount. Note that it tightens against
the landing gear strut before it tightens against the
gear door. Install the second machine screw to hold
the gear door in position. Check to make sure that the
gear door is fl ush with the bottom of the wing. 1.5mm
thick rectangular plywood spacers have been included
to space the gear doors out if needed. Both screws
will need to be shortened, a little at a time, so that they
tighten against both the landing gear strut and the
gear door. Be sure to use threadlocker on the screws.

14. Return to step 1 and mount the retract in the
right wing.
The P-47 was manufactured by Republic Aircraft
Corporation, which at one time was named
Seversky Aircraft Corporation, started by two fellow
Russians, Alexander De Seversky and Alexander
Kartveli.
