  Step 8
Support the fuselage so the wing is not resting on the
work surface. Adjust the strut end so it aligns with the
wing strut mount. Attach the wing struts using two
4-40 x 1/2" socket head bolts and two 4-40 locking
nuts. Once attached, tighten the 4-40 nuts on the strut to
prevent the end from rotating when the wing is removed
for storage.
 Step 9
Repeat Steps 1 through 8 to install the remaining wing
panel and strut.
 Step 10
Install the fuselage hatch using four #2 x 3/8" screws.
Note: When removing the wing, simply
disconnect the bolts holding the strut to the
fuselage. This will make things much easier
when installing the wing at the field.
Note: The struts on the J-3 Cub are
functional, so be sure all bolts and nuts
are tight before flying. Failure to do so
could result in wing failure.
 Step 1
Completely read the instructions included with your
engine and follow the recommended break-in procedure.
 Step 2
At the field, adjust the engine to a slightly rich setting at
full throttle and adjust the idle and low-speed needle so
that a consistent idle is achieved.
 Step 3
Before you fly, be sure that your engine idles reliably,
transitions and runs at all throttle settings. Only
when this is achieved should any plane be considered
ready for flight.
