Section 8: Wing Installation Step 6Slide the wing tube into the wing panel. Slide the tube andpanel into position on the fuselage. Step 8Support the fuselage so the wing is not resting on thework surface. Adjust the strut end so it aligns with thewing strut mount. Attach the wing struts using two4-40 x 1/2" socket head bolts and two 4-40 lockingnuts. Once attached, tighten the 4-40 nuts on the strut toprevent the end from rotating when the wing is removedfor storage. Step 7Secure the wing panel using a 1/4-20 x 2" nylon bolt. Step 9Repeat Steps 1 through 8 to install the remaining wingpanel and strut. Step 10Install the fuselage hatch using four #2 x 3/8" screws.Note: The struts on the J-3 Cub arefunctional, so be sure all bolts and nutsare tight before flying. Failure to do socould result in wing failure.Note: When removing the wing, simplydisconnect the bolts holding the strut to thefuselage. This will make things much easierwhen installing the wing at the field.30
