User Manual
❏❏R4. Cut a 21" [530mm] piece of red air line
tubing and a 16" [400mm] piece of purple air line
tubing from the tubing included with the Robart Air
Control Kit (not included). Connect the red line to the
outer fitting on the air cylinder and connect the
purple line to the inner fitting (the one directly on the
end) on the air cylinder.
❏❏R5. Use a piece of music wire with a hook bent
on the end or something similar to pull the air lines
through the wing. Note that the purple line goes
through the same hole that the air cylinder fits
through, and the red line goes through the round
hole behind it.
❏❏R6. Guide the air lines out the front hole in the
top of the wing and guide the servo wires out the
other hole.
❏❏R7. Mount the retract in the wing. Use a small
screwdriver to move the end of the pushrod coming
from the air cylinder in the retracted (up) position so
the gear doesn’t flop around while joining the wings.
Install the hatch.
❏ R8. Hook up the air lines in the right wing panel
the same way.
Join the wing
Note: Keep the retracts (if installed) in the retracted
(up) position so they do not extend and retract as
you handle the wing.
Because the angle of wing joiner and the angle
of the ribs on the end of the wing panels is
factory-set, checking the dihedral, as would be
done on a built-up kit, is not necessary. However,
for those who insist on checking the dihedral
anyway, this may be done by test fitting the
wings together with the wing joiner. Tightly tape
the wing halves together. The joining ribs on the
end of both panels should fit well with no gap. If
the wing halves do not fit well, remove any glue
blobs or other obstructions that may be
interfering. Once the joining ribs of the two wing
halves fit well, lay the wing upside-down on your
workbench. Measure the distance between the
top of the wing and the workbench at the leading
edge. Also measure the distance from the top of
the wing and the workbench at the trailing edge.
The sum of these two distances should be
5-3/16" [130mm] plus or minus 1/2" [13mm].
