9. Attach the ESC to the ESC mount with four #4 x
½" sheet metal screws and #4 fl at washers.
During speed run testing of early production
P-47s, test pilots attained a level fl ight speed of
over 400 mph.

AIR RETRACT CONTROLS
Pneumatic retracts only. Electrics skip to INSTALL
THE TAIL GEAR COVER.
❏
1. Test fi t the retract servo tray in the fuselage. It
should fi t between the rudder and throttle servo. Drill
a 1/16" (1.6 mm) pilot hole in the servo tray using the
four mounting holes in the retract servo tray as guides.
Attach the retract servo tray with #2 x 3/8" (9.5 mm)
sheet metal screws and #2 fl at washers.
❏
2. Install the retract control valve servo in the retract
servo tray and plug it into the receiver.
❏
3. Assemble the retract control valve mount and
install the retract control valve. Install a .080 ball link
ball and .080 nut on the valve. Be sure to use a drop
of threadlocker on the threads of the ball link ball.
❏
4. Glue the retract control valve mount on the
retract servo tray.
❏
5. Cut off ½" (12.7 mm) from the threaded end of the
2-56 x 6" (152 mm) metal pushrod. Thread the nylon
ball socket on the pushrod. Snap the ball socket onto
the ball link ball on the retract control valve. Mark the
pushrod where it crosses the servo arm and make a
90 degree bend at the mark. Install the pushrod in the
servo arm and install a nylon Faslink. Cut the pushrod
1/8" ( 3 mm) past the top of the Faslink.
❏
6. Install a fi ll valve in the fuselage side in a
convenient location. Refer to the air retracts instructions.
Connect the pressure tank, fi ll valve and control valve
to a T-fi tting. Connect the two air lines coming from the
tail gear retract to separate T-fi ttings. Then, connect
the T-fi ttings to the control valve. Finally connect
the quick connects to the T-fi ttings. Make sure the
quick connectors correspond to the quick connectors
installed in the wing. Electrical tape or nylon tie wraps
can be used to wrap the air lines together to clean up
the installation.
