Fw 190 FACT
The FW 190 was designed with a wide landing
gear which gave it better ground handling on
the rough landing fi elds used during the war.
The landing gear was also raised and lowered
electrically, whereas most fi ghters of that period
used hydraulic systems.
MOUNT THE RETRACTS
Install the left retract fi rst.
❏ ❏
1. Trim the axle that is included with the Robart
retracts to 1-5/8" [41mm] long. File a fl at spot at the end
of the axle. Insert the axle through the included 5-1/4"
[133mm] wheel. Slide the 4mm thick wheel spacer
onto the axle. Insert the axle into the retract. Apply
a drop of threadlocker to the 10-32 x 3/16" [4.8mm]
set screw, included with the retract, and tighten the
set screw onto the fl at of the axle. Make sure that the
wheel rotates freely.
❏ ❏
2. Test fi t the retract unit with the wheel into the
wing. Position the retract so the wheel is centered in
the wheel well. Adjust the strut position in the retract
body as necessary to achieve the correct spacing all
the way around the wheel.
❏ ❏
3. Temporarily attach the retract to the wing with
two 6-32 x 3/4" [19mm] machine screws. Extend the
retract. View the wheel from directly above. Rotate
the strut so that the wheel is parallel to the root of the
wing. Lock the strut in position by applying a drop of
threadlocker to the threads and securely tightening the
bolt at the top of the strut.
❏ ❏
4. Double check that the wheel will fully retract into
the wing. Extend the retract to make sure it does not
interfere with any part of the wing and that the retract
is operating smoothly.
❏ ❏
5. Cut an 18" [457mm] piece of red pressure tubing
and a 23" [584mm] piece of purple pressure tubing from
the tubing included with the Robart Air Control Kit (not
included). Connect the red tube to the front of the air
cylinder and the purple to the back of the air cylinder.
❏ ❏
6. Connect both pressure tubes to the string in
the retract bay. Guide the pressure tubing through the
ribs and out the hole in the top of the wing. Tape the
pressure tubing to the top of the wing.
